Hi,

my name is Hans-Günter Lütke Uphues. I have a question about the
BIOS for the adaptec 2940 SCSI-controler:

I used two SCSI-controlers (Buslogic 130 and Adaptec 2940) for nearly
5 years within my PPro-system without any problems. Some weeks ago I
bought a low-cost ECS-K7S5A board from Elitegroup. Everythings worked
very fine until I installed both SCSI-controlers: The system hangs
after initializing the Buslogic-BIOS without initializing the Adaptec
BIOS.

So I decided to remove the BIOS-chip (release 1.23) from my 2940. Now
I can use both adapters and all connected scsi-devices with my linux
box. Is it ok to remove the BIOS, or are there situations where
the linux driver needs the buildin BIOS? At the moment I use the
following aic7xxx-parameters:

aic7xxx=pci_parity,verbose,aic7xxx=override_term:0x1

'lspci -vv' output:
00:11.0 SCSI storage controller: Adaptec AHA-294x / AIC-7871

        Expansion ROM at cffc0000 [disabled] [size=64K]

The lspci output lists all Expansion ROMs on my PCI/AGP-cards as 'disabled'.

Thanks and a happy new year
Hans-Günter
