While ARCnet is still used in industrial environments, and cards are
still manufactured, it is unlikely anyone is still using it with ISA
and PCMCIA cards. Reduce future maintenance burden by removing all ISA
and PCMCIA ARCnet drivers and documentation related to them. Update
instructions for loading modules and passing parameters to work on
modern kernels and with the com20020_pci driver. Also take the
opportunity to document the rest of the module parameters, correct a
file path in Documentation/networking/arcnet.rst, and change a
reference to /etc/rc.inet1, which no longer exists, to refer to
ifconfig.

Setting the Jumpers
===================
-All ARCnet cards should have a total of four or five different settings:
-
- - the I/O address: this is the "port" your ARCnet card is on. Probed
- values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
- your card has additional ones, which is possible, please tell me.) This
- should not be the same as any other device on your system. According to
- a doc I got from Novell, MS Windows prefers values of 0x300 or more,
- eating net connections on my system (at least) otherwise. My guess is
- this may be because, if your card is at 0x2E0, probing for a serial port
- at 0x2E8 will reset the card and probably mess things up royally.
-
- - Avery's favourite: 0x300.
-
- - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
- on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
-
- Make sure this is different from any other card on your system. Note
- that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
- "cat /proc/interrupts" for a somewhat complete list of which ones are in
- use at any given time. Here is a list of common usages from Vojtech
- Pavlik <vojtech@suse.cz>:
-
- ("Not on bus" means there is no way for a card to generate this
- interrupt)
-
- ====== =========================================================
- IRQ 0 Timer 0 (Not on bus)
- IRQ 1 Keyboard (Not on bus)
- IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
- IRQ 3 COM2
- IRQ 4 COM1
- IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
- IRQ 6 Floppy disk controller
- IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
- IRQ 8 Realtime Clock Interrupt (Not on bus)
- IRQ 9 FREE (VGA vertical sync interrupt if enabled)
- IRQ 10 FREE
- IRQ 11 FREE
- IRQ 12 FREE
- IRQ 13 Numeric Coprocessor (Not on bus)
- IRQ 14 Fixed Disk Controller
- IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
- ====== =========================================================
-
-
- .. note::
-
- IRQ 9 is used on some video cards for the "vertical retrace"
- interrupt. This interrupt would have been handy for things like
- video games, as it occurs exactly once per screen refresh, but
- unfortunately IBM cancelled this feature starting with the original
- VGA and thus many VGA/SVGA cards do not support it. For this
- reason, no modern software uses this interrupt and it can almost
- always be safely disabled, if your video card supports it at all.
-
- If your card for some reason CANNOT disable this IRQ (usually there
- is a jumper), one solution would be to clip the printed circuit
- contact on the board: it's the fourth contact from the left on the
- back side. I take no responsibility if you try this.
-
- - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
-
- - the memory address: Unlike most cards, ARCnets use "shared memory" for
- copying buffers around. Make SURE it doesn't conflict with any other
- used memory in your system!
-
- ::
-
- A0000 - VGA graphics memory (ok if you don't have VGA)
- B0000 - Monochrome text mode
- C0000 \ One of these is your VGA BIOS - usually C0000.
- E0000 /
- F0000 - System BIOS
-
- Anything less than 0xA0000 is, well, a BAD idea since it isn't above
- 640k.
-
- - Avery's favourite: 0xD0000
-
- - the station address: Every ARCnet card has its own "unique" network
- address from 0 to 255. Unlike Ethernet, you can set this address
- yourself with a jumper or switch (or on some cards, with special
- software). Since it's only 8 bits, you can only have 254 ARCnet cards
- on a network. DON'T use 0 or 255, since these are reserved (although
- neat stuff will probably happen if you DO use them). By the way, if you
- haven't already guessed, don't set this the same as any other ARCnet on
- your network!
-
- - Avery's favourite: 3 and 4. Not that it matters.

-entry for more information.
-
-
-Setting the I/O Base Address

-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer requires 2K of a 16K block of RAM. The base of this
-16K block can be located in any of eight positions.
-Switches 4-6 of switch group S1 select the Base of the 16K block.
-Within that 16K address space, the buffer may be assigned any one of four
-positions, determined by the offset, switches 7 and 8 of group S1.

-
- *) To enable the 8K Boot PROM install the jumper ROM.
- The default is jumper ROM not installed.
-
-
-Setting the Timeouts and Interrupt
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The jumpers labeled EXT1 and EXT2 are used to determine the timeout
-parameters. These two jumpers are normally left open.
-
-To select a hardware interrupt level set one (only one!) of the jumpers
-IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
-
-
-Configuring the PC130E for Star or Bus Topology
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The single jumper labeled STAR is used to configure the PC130E board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
-^^^^^^^^^^^^^^^
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity::
-
- Green | Status Red | Status
- -------|------------------- ---------|-------------------
- on | normal activity flash/on | data transfer
- blink | reconfiguration off | no data transfer;
- off | defective board or | incorrect memory or
- | node ID is zero | I/O address
-
-
-PC500/PC550 Longboard (16-bit cards)
-------------------------------------
-
- - from Juergen Seifert <seifert@htwm.de>
-
-
- .. note::
-
- There is another Version of the PC500 called Short Version, which
- is different in hard- and software! The most important differences
- are:
-
- - The long board has no Shared memory.
- - On the long board the selection of the interrupt is done by binary
- coded switch, on the short board directly by jumper.
-
-[Avery's note: pay special attention to that: the long board HAS NO SHARED
-MEMORY. This means the current Linux-ARCnet driver can't use these cards.
-I have obtained a PC500Longboard and will be doing some experiments on it in
-the future, but don't hold your breath. Thanks again to Juergen Seifert for
-his advice about this!]

-
-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in group SW3 are used to set the node ID. Each node
-attached to the network must have an unique node ID which must be
-different from 0.
-Switch 1 serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Value
- -------|-------
- 1 | 1
- 2 | 2
- 3 | 4

-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The first six switches in switch group SW1 are used to select one
-of 32 possible I/O Base addresses using the following table::
-
- Switch | Hex I/O
- 6 5 4 3 2 1 | Address
- -------------|--------
- 0 1 0 0 0 0 | 200

-
-Setting the Interrupt
-^^^^^^^^^^^^^^^^^^^^^
-
-Switches seven through ten of switch group SW1 are used to select the
-interrupt level. The interrupt level is binary coded, so selections
-from 0 to 15 would be possible, but only the following eight values will
-be supported: 3, 4, 5, 7, 9, 10, 11, 12.
-
-::
-
- Switch | IRQ
- 10 9 8 7 |
- ---------|--------
- 0 0 1 1 | 3
- 0 1 0 0 | 4
- 0 1 0 1 | 5
- 0 1 1 1 | 7
- 1 0 0 1 | 9 (=2) (default)
- 1 0 1 0 | 10
- 1 0 1 1 | 11
- 1 1 0 0 | 12
-
-
-Setting the Timeouts
-^^^^^^^^^^^^^^^^^^^^
-
-The two jumpers JP2 (1-4) are used to determine the timeout parameters.
-These two jumpers are normally left open.
-Refer to the COM9026 Data Sheet for alternate configurations.
-
-
-Configuring the PC500 for Star or Bus Topology
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The single jumper labeled JP6 is used to configure the PC500 board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
-^^^^^^^^^^^^^^^
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity::
-
- Green | Status Red | Status
- -------|------------------- ---------|-------------------
- on | normal activity flash/on | data transfer
- blink | reconfiguration off | no data transfer;
- off | defective board or | incorrect memory or
- | node ID is zero | I/O address
-

-PC710 (8-bit card)
-------------------
-
- - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
-
-Note: this data is gathered by experimenting and looking at info of other
-cards. However, I'm sure I got 99% of the settings right.
-
-The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
-LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::
-

- |||||||||||||||||||||
-
-The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
-labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
-IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
-
-S1 and S2 perform the same function as on the PC270, only their numbers
-are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
-
-I know it works when connected to a PC110 type ARCnet board.

-LCS-8830(-T) (8 and 16-bit cards)
----------------------------------
-
- - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
- - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
- LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
- only (the JP0 jumper is hardwired), and BNC only.
-
-This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
-nowhere else, not even on the few Xeroxed sheets from the manual).

-PDI507 (8-bit card)
---------------------
-
- - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
- - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
- are mostly the same as this. PDI508Plus cards appear to be mainly
- software-configured.
-
-Jumpers:
-
- There is a jumper array at the bottom of the card, near the edge
- connector. This array is labelled J1. They control the IRQs and
- something else. Put only one jumper on the IRQ pins.
-
- ETS1, ETS2 are for timing on very long distance networks. See the
- more general information near the top of this file.
-
- There is a J2 jumper on two pins. A jumper should be put on them,
- since it was already there when I got the card. I don't know what
- this jumper is for though.
-
- There is a two-jumper array for J3. I don't know what it is for,
- but there were already two jumpers on it when I got the card. It's
- a six pin grid in a two-by-three fashion. The jumpers were
- configured as follows::
-
- .-------.
- o | o o |
- :-------: ------> Accessible end of card with connectors
- o | o o | in this direction ------->
- `-------'
-
-Carl de Billy <CARL@carainfo.com> explains J3 and J4:

-
- - If using coax cable in a bus topology the J4 jumper must be removed;
- place it on one pin.
-
- - If using bus topology with twisted pair wiring move the J3
- jumpers so they connect the middle pin and the pins closest to the RJ11
- Connectors. Also the J4 jumper must be removed; place it on one pin of
- J4 jumper for storage.
-
- - If using star topology with twisted pair wiring move the J3
- jumpers so they connect the middle pin and the pins closest to the RJ11
- connectors.
-
-
-DIP Switches:
-
- The DIP switches accessible on the accessible end of the card while
- it is installed, is used to set the ARCnet address. There are 8
- switches. Use an address from 1 to 254
-
- ========== =========================
- Switch No. ARCnet address
- 12345678
- ========== =========================
- 00000000 FF (Don't use this!)
- 00000001 FE
- 00000010 FD
- ...
- 11111101 2
- 11111110 1
- 11111111 0 (Don't use this!)
- ========== =========================
-
- There is another array of eight DIP switches at the top of the
- card. There are five labelled MS0-MS4 which seem to control the
- memory address, and another three labelled IO0-IO2 which seem to
- control the base I/O address of the card.
-
- This was difficult to test by trial and error, and the I/O addresses
- are in a weird order. This was tested by setting the DIP switches,
- rebooting the computer, and attempting to load ARCETHER at various
- addresses (mostly between 0x200 and 0x400). The address that caused
- the red transmit LED to blink, is the one that I thought works.
-
- Also, the address 0x3D0 seem to have a special meaning, since the
- ARCETHER packet driver loaded fine, but without the red LED
- blinking. I don't know what 0x3D0 is for though. I recommend using
- an address of 0x300 since Windows may not like addresses below
- 0x300.
-
- ============= ===========
- IO Switch No. I/O address
- 210
- ============= ===========
- 111 0x260
- 110 0x290
- 101 0x2E0
- 100 0x2F0
- 011 0x300
- 010 0x350
- 001 0x380
- 000 0x3E0
- ============= ===========
-
- The memory switches set a reserved address space of 0x1000 bytes
- (0x100 segment units, or 4k). For example if I set an address of
- 0xD000, it will use up addresses 0xD000 to 0xD100.
-
- The memory switches were tested by booting using QEMM386 stealth,
- and using LOADHI to see what address automatically became excluded
- from the upper memory regions, and then attempting to load ARCETHER
- using these addresses.
-
- I recommend using an ARCnet memory address of 0xD000, and putting
- the EMS page frame at 0xC000 while using QEMM stealth mode. That
- way, you get contiguous high memory from 0xD100 almost all the way
- the end of the megabyte.
-
- Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
- on my card. It could be malfunctioning on my card. Experiment with
- it ON first, and if it doesn't work, set it to OFF. (It may be a
- modifier for the 0x200 bit?)

-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must be different from 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:

-
-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the following table::
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260
- OFF ON ON | 290
- ON OFF ON | 2E0 (Manufacturer's default)
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 8K or memory base + 0x2000.
-Switches 1-5 of switch block SW1 select the Memory Base address.
-
-::
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
- *) To enable the Boot ROM install the jumper JP1
-
-.. note::
-
- Since the switches 1 and 2 are always set to ON it may be possible
- that they can be used to add an offset of 2K, 4K or 6K to the base
- address, but this feature is not documented in the manual and I
- haven't tested it yet.
-
-

-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must be different from 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2
- 3 | ID2 | 4
- 4 | ID3 | 8
- 5 | ID4 | 16

-
-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The first six switches in switch block SW1 are used to select the I/O Base
-address using the following table::
-
- Switch | Hex I/O
- 1 2 3 4 5 6 | Address
- ------------------------|--------
- OFF ON ON OFF OFF ON | 260
- OFF ON OFF ON ON OFF | 290
- OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)
- OFF ON OFF OFF OFF OFF | 2F0
- OFF OFF ON ON ON ON | 300
- OFF OFF ON OFF ON OFF | 350
- OFF OFF OFF ON ON ON | 380
- OFF OFF OFF OFF OFF ON | 3E0
-
-Note: Other IO-Base addresses seem to be selectable, but only the above
- combinations are documented.
-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The switches 7-10 of switch block SW1 are used to select the Memory
-Base address of the RAM (2K) and the PROM::
-
- Switch | Hex RAM | Hex ROM
- 7 8 9 10 | Address | Address
- ----------------|---------|-----------
- OFF OFF ON ON | C0000 | C8000
- OFF OFF ON OFF | D0000 | D8000 (Default)
- OFF OFF OFF ON | E0000 | E8000
-
-.. note::
-
- Other MEM-Base addresses seem to be selectable, but only the above
- combinations are documented.
-
-
-Setting the Interrupt Line
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To select a hardware interrupt level install one (only one!) of the jumpers
-JP3 through JP13 using the following table::
-
- Jumper | IRQ
- -------|-----------------
- 3 | 14
- 4 | 15
- 5 | 12
- 6 | 11
- 7 | 10
- 8 | 3
- 9 | 4
- 10 | 5
- 11 | 6
- 12 | 7
- 13 | 2 (=9) Default!
-
-.. note::
-
- - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
- Controller
- - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
- Hard Disk, it may conflict with their controllers
-
-
-Setting the Timeout Parameters
-------------------------------
-
-The jumpers labeled JP1 and JP2 are used to determine the timeout
-parameters. These two jumpers are normally left open.

-
-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must not be 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-Setting one of the switches to OFF means "1", ON means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Value
- -------|-------
- 1 | 1
- 2 | 2
- 3 | 4
- 4 | 8
- 5 | 16
- 6 | 32
- 7 | 64
- 8 | 128
-
-Don't set this to 0 or 255; these values are reserved.
-
-
-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The switches 1 to 6 of switch block SW1 are used to select one
-of 32 possible I/O Base addresses using the following tables::
-
- | Hex
- Switch | Value
- -------|-------
- 1 | 200
- 2 | 100
- 3 | 80
- 4 | 40
- 5 | 20
- 6 | 10
-
-The I/O address is sum of all switches set to "1". Remember that
-the I/O address space below 0x200 is RESERVED for mainboard, so
-switch 1 should be ALWAYS SET TO OFF.
-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of sixteen positions. However, the addresses below
-A0000 are likely to cause system hang because there's main RAM.
-
-Jumpers 7-10 of switch block SW1 select the Memory Base address::
-
- Switch | Hex RAM
- 7 8 9 10 | Address
- ----------------|---------
- OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
- OFF OFF OFF ON | E0000
- OFF OFF ON OFF | D0000
- OFF OFF ON ON | C0000 (conflicts with video BIOS)
- OFF ON OFF OFF | B0000 (conflicts with mono video)
- OFF ON OFF ON | A0000 (conflicts with graphics)
-
-
-Setting the Interrupt Line
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
-shorted, OFF means open::
-
- Jumper | IRQ
- 1 2 3 4 5 |
- ----------------------------
- ON OFF OFF OFF OFF | 7
- OFF ON OFF OFF OFF | 5
- OFF OFF ON OFF OFF | 4
- OFF OFF OFF ON OFF | 3
- OFF OFF OFF OFF ON | 2
-
-
-Unknown jumpers & sockets
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-I know nothing about these. I just guess that J16&J17 are timeout
-jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
-J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
-guess the purpose.

-
-There is a DIP-switch with 8 switches, used to set the shared memory address
-to be used. The first 6 switches set the address, the 7th doesn't have any
-function, and the 8th switch is used to select "compatible" or "enhanced".
-When I got my two cards, one of them had this switch set to "enhanced". That
-card didn't work at all, it wasn't even recognized by the driver. The other
-card had this switch set to "compatible" and it behaved absolutely normally. I
-guess that the switch on one of the cards, must have been changed accidentally
-when the card was taken out of its former host. The question remains
-unanswered, what is the purpose of the "enhanced" position?
-
-[Avery's note: "enhanced" probably either disables shared memory (use IO
-ports instead) or disables IO ports (use memory addresses instead). This
-varies by the type of card involved. I fail to see how either of these
-enhance anything. Send me more detailed information about this mode, or
-just use "compatible" mode instead.]

- - from Robert Michael Best <rmb117@cs.usask.ca>
-
-[Avery's note: these don't work with my driver for some reason. These cards
-SEEM to have settings similar to the PDI508Plus, which is
-software-configured and doesn't work with my driver either. The "Waterloo
-chip" is a boot PROM, probably designed specifically for the University of
-Waterloo. If you have any further information about this card, please
-e-mail me.]
-
-The probe has not been able to detect the card on any of the J2 settings,
-and I tried them again with the "Waterloo" chip removed.

-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in group SW1 are used to set the node ID.
-Each node attached to the network must have an unique node ID which
-must be different from 0.
-Switch 8 serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Value
- -------|-------
- 8 | 1
- 7 | 2
- 6 | 4
- 5 | 8
- 4 | 16
- 3 | 32

-
-
-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The first three switches in switch group SW2 are used to select one
-of eight possible I/O Base addresses using the following table::
-
- Switch | Hex I/O
- 1 2 3 | Address
- ------------|--------
- ON ON ON | 260
- ON ON OFF | 290
- ON OFF ON | 2E0 (Manufacturer's default)
- ON OFF OFF | 2F0
- OFF ON ON | 300
- OFF ON OFF | 350
- OFF OFF ON | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer requires 2K of a 16K block of RAM. The base of this
-16K block can be located in any of eight positions.
-Switches 4-6 of switch group SW2 select the Base of the 16K block.
-Within that 16K address space, the buffer may be assigned any one of four
-positions, determined by the offset, switches 7 and 8 of group SW2.
-
-::
-
- Switch | Hex RAM | Hex ROM
- 4 5 6 7 8 | Address | Address *)

-
- *) To enable the 8K Boot PROM install the jumper ROM.
- The default is jumper ROM not installed.
-
-
-Setting Interrupt Request Lines (IRQ)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To select a hardware interrupt level set one (only one!) of the jumpers
-IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
-
-
-Setting the Timeouts
-^^^^^^^^^^^^^^^^^^^^
-
-The two jumpers labeled ET1 and ET2 are used to determine the timeout
-parameters (response and reconfiguration time). Every node in a network
-must be set to the same timeout values.
-
-::
-
- ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
- --------|--------------------|--------------------------
- Off Off | 78 | 840 (Default)
- Off On | 285 | 1680
- On Off | 563 | 1680
- On On | 1130 | 1680
-
-On means jumper installed, Off means jumper not installed
-
-
-16-BIT ARCNET
--------------
-
-The manual of my 8-Bit NONAME ARCnet Card contains another description
-of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
-because there are missing two pages in the manual booklet. (The table
-of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
-the booklet there is a different way of counting ... 2-9, 2-10, A-1,
-(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
-Also the picture of the board layout is not as good as the picture of
-8-Bit card, because there isn't any letter like "SW1" written to the
-picture.
-
-Should somebody have such a board, please feel free to complete this
-description or to send a mail to me!

- 6-8: Base I/O Address Select
- SW2 1-8: Node ID Select (ID0-ID7)
- SW3 1-5: IRQ Select
- 6-7: Extra Timeout
- 8 : ROM Enable
- JP1 Led connector
- BNC Coax connector
-
-Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
-switches.
-
-Setting the jumpers to ON means connecting the upper two pins, off the bottom
-two - or - in case of IRQ setting, connecting none of them at all.
-
-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must not be 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-Setting one of the switches to Off means "1", On means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2
- 3 | ID2 | 4
- 4 | ID3 | 8

-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the following table::
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260
- OFF ON ON | 290
- ON OFF ON | 2E0 (Manufacturer's default)
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 0x2000.
-
-Jumpers 3-5 of jumper block SW1 select the Memory Base address.
-
-::
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
- *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
-
-The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
-
-Setting the Interrupt Line
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Jumpers 1-5 of the jumper block SW3 control the IRQ level::
-
- Jumper | IRQ
- 1 2 3 4 5 |
- ----------------------------
- ON OFF OFF OFF OFF | 2
- OFF ON OFF OFF OFF | 3
- OFF OFF ON OFF OFF | 4
- OFF OFF OFF ON OFF | 5
- OFF OFF OFF OFF ON | 7
-
-
-Setting the Timeout Parameters
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
-parameters. These two jumpers are normally left in the OFF position.

-SW1: Timeouts, Interrupt and ROM
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-To select a hardware interrupt level set one (only one!) of the dip switches
-up (on) SW1...(switches 1-5)
-IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
-
-The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
-are used to determine the timeout parameters. These two dip switches
-are normally left off (down).
-
- To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
- The default is jumper ROM not installed.
-
-
-Setting the I/O Base Address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The last three switches in switch group SW2 are used to select one
-of eight possible I/O Base addresses using the following table::
-
-
- Switch | Hex I/O
- 4 5 6 | Address
- -------|--------
- 0 0 0 | 260
- 0 0 1 | 290
- 0 1 0 | 2E0 (Manufacturer's default)
- 0 1 1 | 2F0
- 1 0 0 | 300
- 1 0 1 | 350
- 1 1 0 | 380
- 1 1 1 | 3E0
-
-
-Setting the Base Memory Address (RAM & ROM)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The memory buffer requires 2K of a 16K block of RAM. The base of this
-16K block can be located in any of eight positions.
-Switches 1-3 of switch group SW2 select the Base of the 16K block.
-(0 = DOWN, 1 = UP)
-I could, however, only verify two settings...
-
-
-::
-
- Switch| Hex RAM | Hex ROM
- 1 2 3 | Address | Address
- ------|---------|-----------
- 0 0 0 | E0000 | E2000
- 0 0 1 | D0000 | D2000 (Manufacturer's default)
- 0 1 0 | ????? | ?????
- 0 1 1 | ????? | ?????
- 1 0 0 | ????? | ?????
- 1 0 1 | ????? | ?????
- 1 1 0 | ????? | ?????
- 1 1 1 | ????? | ?????
-
-
-Setting the Node ID
-^^^^^^^^^^^^^^^^^^^
-
-The eight switches in group SW3 are used to set the node ID.
-Each node attached to the network must have an unique node ID which
-must be different from 0.
-Switch 1 serves as the least significant bit (LSB).
-switches in the DOWN position are OFF (0) and in the UP position are ON (1)
-
-The node ID is the sum of the values of all switches set to "1"
-These values are::
-
- Switch | Value
- -------|-------
- 1 | 1
- 2 | 2
- 3 | 4
- 4 | 8
- 5 | 16
- 6 | 32
- 7 | 64
- 8 | 128
-
-Some Examples::
-
- Switch# | Hex | Decimal

-Installing the Driver
----------------------
-All you will need to do in order to install the driver is::
+Supported Hardware
+------------------
- make config
- (be sure to choose ARCnet in the network devices
- and at least one chipset driver.)
- make clean
- make zImage
+Only PCI and PCI Express devices based on the COM20020 chipset are supported.
+This is the newest chipset from SMC with support for promiscuous mode (packet
+sniffing), extra diagnostic information, etc. These devices use the com20020_pci
+driver.
-If you obtained this ARCnet package as an upgrade to the ARCnet driver in
-your current kernel, you will need to first copy arcnet.c over the one in
-the linux/drivers/net directory.
+Support for older chipsets and ISA and PCMCIA devices was previously available
+but has been removed.
-You will know the driver is installed properly if you get some ARCnet
-messages when you reboot into the new Linux kernel.
-There are four chipset options:
-
- 1. Standard ARCnet COM90xx chipset.
-
-This is the normal ARCnet card, which you've probably got. This is the only
-chipset driver which will autoprobe if not told where the card is.
-It following options on the command line::
-
- com90xx=[<io>[,<irq>[,<shmem>]]][,<name>] | <name>
-
-If you load the chipset support as a module, the options are::
-
- io=<io> irq=<irq> shmem=<shmem> device=<name>
-
-To disable the autoprobe, just specify "com90xx=" on the kernel command line.
-To specify the name alone, but allow autoprobe, just put "com90xx=<name>"
-
- 2. ARCnet COM20020 chipset.
+Configuring the Driver
+----------------------
-This is the new chipset from SMC with support for promiscuous mode (packet
-sniffing), extra diagnostic information, etc. Unfortunately, there is no
-sensible method of autoprobing for these cards. You must specify the I/O
-address on the kernel command line.
+The COM20020 driver will be loaded automatically at boot if a supported card is
+detected.
-The command line options are::
+If the com20020_pci driver was compiled as a loadable module, the options are::
- com20020=<io>[,<irq>[,<node_ID>[,backplane[,CKP[,timeout]]]]][,name]
+ node=<node_ID> backplane=<backplane> clockp=<CKP> clockm=<CKM>
+ timeout=<timeout> device=<interface_name>
-If you load the chipset support as a module, the options are::
+If the driver was compiled into the kernel, the same options can be specified on
+the kernel command line by prefixing them with `com20020_pci.`, as in the
+following example::
- io=<io> irq=<irq> node=<node_ID> backplane=<backplane> clock=<CKP>
- timeout=<timeout> device=<name>
+ com20020_pci.device=eth1
The COM20020 chipset allows you to set the node ID in software, overriding the
default which is still set in DIP switches on the card. If you don't have the
-COM20020 data sheets, and you don't know what the other three options refer
+COM20020 data sheets, and you don't know what the other options refer
to, then they won't interest you - forget them.
- 3. ARCnet COM90xx chipset in IO-mapped mode.
-
-This will also work with the normal ARCnet cards, but doesn't use the shared
-memory. It performs less well than the above driver, but is provided in case
-you have a card which doesn't support shared memory, or (strangely) in case
-you have so many ARCnet cards in your machine that you run out of shmem slots.
-If you don't give the IO address on the kernel command line, then the driver
-will not find the card.
-
-The command line options are::
-
- com90io=<io>[,<irq>][,<name>]
-
-If you load the chipset support as a module, the options are:
- io=<io> irq=<irq> device=<name>
-
- 4. ARCnet RIM I cards.
-
-These are COM90xx chips which are _completely_ memory mapped. The support for
-these is not tested. If you have one, please mail the author with a success
-report. All options must be specified, except the device name.
-Command line options::
-
- arcrimi=<shmem>,<irq>,<node_ID>[,<name>]
-
-If you load the chipset support as a module, the options are::
-
- shmem=<shmem> irq=<irq> node=<node_ID> device=<name>
-
-
-Loadable Module Support
------------------------
-
-Configure and rebuild Linux. When asked, answer 'm' to "Generic ARCnet
-support" and to support for your ARCnet chipset if you want to use the
-loadable module. You can also say 'y' to "Generic ARCnet support" and 'm'
-to the chipset support if you wish.
-
-::
-
- make config
- make clean
- make zImage
- make modules
-
-If you're using a loadable module, you need to use insmod to load it, and
-you can specify various characteristics of your card on the command
-line. (In recent versions of the driver, autoprobing is much more reliable
-and works as a module, so most of this is now unnecessary.)
-
-For example::
-
- cd /usr/src/linux/modules
- insmod arcnet.o
- insmod com90xx.o
- insmod com20020.o io=0x2e0 device=eth1
-
-
-Using the Driver
-----------------
-
-If you build your kernel with ARCnet COM90xx support included, it should
-probe for your card automatically when you boot. If you use a different
-chipset driver complied into the kernel, you must give the necessary options
-on the kernel command line, as detailed above.
-
-Go read the NET-2-HOWTO and ETHERNET-HOWTO for Linux; they should be
-available where you picked up this driver. Think of your ARCnet as a
-souped-up (or down, as the case may be) Ethernet card.
-
-By the way, be sure to change all references from "eth0" to "arc0" in the
-HOWTOs. Remember that ARCnet isn't a "true" Ethernet, and the device name
-is DIFFERENT.
-
-
-Multiple Cards in One Computer
-------------------------------
-
-Linux has pretty good support for this now, but since I've been busy, the
-ARCnet driver has somewhat suffered in this respect. COM90xx support, if
-compiled into the kernel, will (try to) autodetect all the installed cards.
-
-If you have other cards, with support compiled into the kernel, then you can
-just repeat the options on the kernel command line, e.g.::
-
- LILO: linux com20020=0x2e0 com20020=0x380 com90io=0x260
-
-If you have the chipset support built as a loadable module, then you need to
-do something like this::
-
- insmod -o arc0 com90xx
- insmod -o arc1 com20020 io=0x2e0
- insmod -o arc2 com90xx
-
-The ARCnet drivers will now sort out their names automatically.
+Otherwise, ARCnet can be configured in a similar way to Ethernet, with the
+exception that ARCnet interface names begin with `arc`.
