[K12OSN] SCSI RAID still not detected...

I had a similar problem but with different Adaptec SCSI controller.

Early in the install process you are able to point to cards that are not
detected. There are about 5 or 6 adaptec controllers in the list. One of
them might work for you. I ended up using the card as a regular
controller and then using the Fedora software raid.

FWIW: We have now used scsi hardware raid, a 3Ware ATA raid controller,
and now, scsi with software raid. All work very well.

One of these days I'd like to run bonnie++ or some other software to
compare the disk performance of each solution.

Try this one 


your chip is aic 7930w so 79xx should work but you will have to compile
it and
install it yourself. I'm not sure how to do it. You might want to ask
for help. Also you will have to disable RAID support in the bios as this
is for non RAID. I have the non RAID aic 7902 on my MB and it works fine
supplied driver from adaptec but I'm using 3.1.2 (RH9) Although kernel
2.6.5 and
above should have this by default. Again no hardware RAID. You could do
RAID with Kernel it's probably very comparable in terms of performance.
