Slow down.. Your missing a few important details. When you recompiled the
kernel, did you compile ISO9660 support, as well as SCSI CDROM support?
How did you install the new kernel? Are you using lilo? Which options
did you select for the adaptec during the kernel compile?

The defaults will work fine. Be absolutly sure you have termination
correct. Do you have any external devices? The 2940UW cannot use all
three interfaces at once. So, the Barraduca is on the 68-pin interface,
and the CDROM is on the 50-pin interface, correct? If so, you need to
disable Low Termination, and enable High, as well as terminate both the
CDROM and the hard disk.
Also, it was most likely not necessary to recompile the kernel. The stock
kernel has aic7xxx support, and CDROM support already compiled.
