	I have two Adaptec SCSI card in my box,
	1) 2940 UW  (Wide device attached Hardrive)
	2) 2910 CD  (Narrow devices attached, Scanner, CDRW)

	I had no problem with either 2.0.36 nor 2.2.10.
	The difference I see is that my 2910CD does not have an
on board BIOS, so there is no conflict at boot time. 
	I think you should disable the bios of one of the 2 cards
(you must keep the BIOS enabled on the card where your boot device
 is attached)

	Just a hint, I'm not an expert. :))
