OK. It seems you suffered from some brokem PCI-Bridge-Chip, not from SCSI !

I don't know, wether the Buslogic will do any better, when the problem is in the PCI-Bridge-Chip ?!

I've had meanwhile 3 486-Boards with VIP (VESA, ISA & PCI) - I also had the whole time SCSI-Host-Adapters ( It's been all the time an NCR 825S and an AHA2940W ). And I never had any troubles with them! (Except with the last Board, from SOYO. It's a 4SAW2. It supports only SDMS 3.06 (from 1993 !!! - And the board is brand new!) and alway make some funny things with my NCR. I have upgraded the BIOS of the NCR to SDMS 4.x, but the 4.x Driver for Win 3.11 for example claims, that it won't support such an old SDMS-Version. So I can't have 32-bit under Win 3.11. - But- I mostly use Linux, anyway! :-)))))))))
But with these 2 SCSI-Controllers in the same system, you will always have some wild *FUN* ;)
This is obvious when I install a new (complete) Distribution.
It works mostly the following way: I boot my machine under DOS and start the installation-Tool from CD. The boot-disk and the CD-ROM are connected to the NCR. So the newly booted Linux accepts them as /dev/sda1 and the CD-ROM is always OK [No need to mention further]. I apply the new distribution to one Partition at the Adaptec, which is known then as "/dev/sdc1" (/dev/sdb is at the NCR, too).
The Installationtool creates a "/etc/fstab" with these settings. - But when I try to boot Linux anew (loadlin...), Linux claims that the Disk at the Adaptec is "/dev/sda1" - Can you imagine how much fun I have, when I forget to fix the fstab, before rebooting ? - Especially, when you have (as I have) 4 disks and 2 or more swap-Partitions on different disks with different partition-Numbers ? X-[ - Yes, you could call it "Eraserhead" ;-] or "Russian Roulette".
