Drives on Promise PDC20265 card not recognized (2.4.21-rc7, Compaq Deskpro 2000)

[Jurriaan]

I have a strange problem with my Promise PDC20265 udma-controller in a
Compaq Deskpro 2000 system.

Whatever drives I put on this card, linux doesn't see them.
Adding 'hde=59556,16,63' to lilo.conf only creates a message about a
non-ide drive in dmesg-output. The card itself is probed alright,
io-ports and interrupts seem to be OK.

I am convinced this stupid Compaq BIOS somehow works against me.
Unfortunately, I can't change that.

Has anybody seen something like this before, and found a solution?

even something as simple as hdparm -i /dev/hdg fails:

/dev/hdg:

Any hints?

Thanks,
