Thanks for the reply.
I agree about using google before asking. I have been google(ing) for days but haven't managed to find anything that seemed to help. I was hoping someone knew something that google hadn't found.
Initially, I tried the slackware 10.1 adaptec.s because the website description looked very promising:
adaptec.s: This bootdisk supports most Adaptec SCSI controllers, including these models: AHA-1510, AHA-1520, AHA-1522, AHA-1522, AHA-1740, and AHA-2825. The AIC7xxx models, which include the 274x EISA cards; 284x VLB cards; 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and motherboard based SCSI controllers from Adaptec. Adaptec's I2O based RAID controllers (including OEM Adaptec RAID controllers used by HP and Dell, Adaptec branded AAC964/5400 RAID controllers, and DPT SmartRaid V cards).
When this didn't seem to work I started with google. The best I came up is to install an IDE disk, load slackware, and build a new kernel with the appropriate SCSI support.
BUT, just now I'm not sure I can put an IDE disk into the server and I don't have a spare box to load slackware 10.1 on either.
Anyway, I'm not at the end of the road yet and thanks for your reply.
