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

Region 1: Memory at cfffb000 (32-bit, non-prefetchable) [size=4K]
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
