Promise Ultra/66

[Simon Piette <spiette@generation.net>]

Hi,

I'm currently trying to get working a Promise Ultra/66 (BIOS v 1.14) on
a 2.2.12 kernel and/or a 2.2.15 kernel both from kernel.org, as Michael
Lanners used those. I would like to have it to work on a Umax J700/180
(the actual machine) and a StarMax 3200/240

For the former (2.2.12 kernel), I got the ide-2.2.12 patch form Andre
Hedrick (http://www.kernel.org/pub/linux/kernel/people/hedrick)
and applied the patch from Michael Lanners
(http://lists.linuxppc.org/listarcs/linuxppc-dev/199909/msg00146.html)

The patches applied without any hitch (no .rej). My config file got:
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_PDC202XX=y
CONFIG_BLK_DEV_IDE_PMAC=y
CONFIG_BLK_DEV_IDEDMA_PMAC=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_INITRD=y
CONFIG_BLK_DEV_IDE_MODES=y
CONFIG_BLK_DEV_SD=y
CONFIG_BLK_DEV_SR=y

And I can't built vmlinux:

I had to apply some patch from ML:
http://lists.linuxppc.org/listarcs/linuxppc-dev/199908/msg00096.html

then manually add:
--- pmac_setup.c.orig   Mon May 15 19:39:53 2000

And I got the same result than for 2.2.15...

For the latter (2.2.15), I took the ide.2.2.15.20000509.patch from A. Hedrick,
but I didn't applied Michael Lanners', since it looks as it's already
merged. Same .config, plus make oldconfig.

It build succesfully. I can boot with it (from a scsi drive). At boot,
it shows:

ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
PDC20262: IDE controller on PCI bus 01 dev 00
PDC20262: device not capable of full native PCI mode
PDC20262: device disabled (BIOS)

BTW, I've tried with "idebus=66" as kernel args, but I'm not sure if my
mobo would support that.


For the record, here's the lspci -vvx output:

Do I have to setup the card BIOS on a PC before getting it to work?

Should I enable PCI_QUIRKS? Put the Promise Card in bus 0 instead?

Do I need addtionnal patches?

Comments, suggestions, kernel args?

Cheers,

Simon Piette
