Thanks for your advice, Bill.
I have followed what you wrote, but still it doesn't work. I
included the SCSI optinos in the kernel (not as modules), but I am
getting "unresolved symbol" errors in "/lib/aic7xxx.o", after I am
told that linux is Loading the module. Finally the kernel panics,
being "Unable to mount root fs" - which is understandable if it can't
load the SCSI driver.
