parport not detected

parport not detected

[Michael B. Allen]

The parallel port is not being detected on my ABIT KT7A KT133 w/ Athlon
900 running 2.2.17 w/ Hendricks IDE patches and RH 6.2. I tried most of
the settings in the bios.

BIOS options are:

728/IRQ5
378/IRQ7
3BC/IRQ7

with the possible modes:

Normal
EPP
	1.9 or 1.7
ECP
	DMA 3 or 1
ECP+EPP
	1.9 or 1.7 and DMA 3 or 1

Of the above what's optimal?

[miallen@nano /etc]$ cat conf.modules
alias eth0 3c59x
alias char-major-6 parport_pc
alias parport_lowlevel parport_pc

Also, the module is loading with depmod:

[miallen@nano 0]$ for i in /proc/parport/0/*; do echo $i; cat $i; done
/proc/parport/0/autoprobe
/proc/parport/0/devices
/proc/parport/0/hardware
base:   0x3bc
irq:    none
dma:    none
modes:  SPP
/proc/parport/0/irq
none

I also tried an options line in modules.conf. I believe it was:

options parport_pc io=0x3bc irq=7

That was reflected in /proc but no difference in actually "detecting"
the parallel port. I did see the light come on on the printer once
though. Also, if I build parpart into the kernel I get nothing but a
hard lockup on 'Starting kswapd v 1.5'.

Any ideas?

Thanks,
Mike

Also try comp.os.linux.hardware.

BIOS
----
278/irq5
378/irq7
EPP 1.9

.config
-------
CONFIG_PARPORT=y
CONFIG_PARPORT_PC=y
CONFIG_PNP=y

CONFIG_PRINTER=y
CONFIG_PRINTER_READBACK=y

kernal boot params
------------------
append="parport=0x378,7 parport=0x278,5"

options for /etc/rc.d/rc.local

/usr/sbin/tunelp /dev/lp0 -a on -o on -T on
/usr/sbin/tunelp /dev/lp1 -a on -o on -T on

looks like this (lp1 was powered down at boot time)

Yup!

nano kernel: parport0: PC-style at 0x378, irq 7 [SPP,PS2,EPP] 
nano kernel: parport0: Printer, Hewlett-Packard HP LaserJet 6L

I setup everything as you describe below. I don't remember having to
do all this stuff before(on other machines anyway). I guess I'm used to
RH's fluffed-up stock kernels.

Thanks,
Mike

Which stock kernel didn't work for you?

Need dmesg output to see what parport is being told and what is
finding out for itself.

But which one is it actually set to?

It depends what you're doing, really.

Take that out and see what happens.

I don't know what you mean really.  Are you saying that you can't
print, or just that the device ID probe (to get the printer name)
isn't working?

That's quite strange.

Which kernel version are you using?  Take a look at the
'troubleshooting' section of Documentation/parport.txt.
