RE: Promise PDC20262 in kernel 2.4.x

Hi,
and how about IRQ sharing? I wonder that Promise cards are little bit
selfish about their resources, because I spent a lot of time setting them up
to cooperate with rest of hardware (scsi controller, ide onboard
controllers, NIC etc.). Finally I discovered, that my Promise controller had
to have polished setup in BIOS to init&boot correctly:
1) PCI-IDE map to <PCI slot # of Promise card>
2) PCI-IRQ on <PCI slot # of Promise card> setup to some certain value, as
high as possible (not AUTO)
3)in PCI/PnP section of BIOS set this value as USED BY ISA (if I remember
well :)
4) of course setup your BIOS to "Not PnP OS (even if linux is PnP)"

I hope this can help.

Regards,
Petr
