How hard would it be to add a kernel command line option? Something
like "scsi-order=aic7xxx,eata-dma"? I understand that if you reorder
some of the probes bad things will happen, but that could be checked
for. That way it doesn't matter which way the kernel default is, I
could put a line like the above in my lilo.conf and it would be
automatic.

I went through great pains trying to figure out how my Tomcat II
motherboard decided which SCSI adapter to boot from. It tries to boot
the same adapter it booted last time. I has installed the DPT first (to
set up the RAID), and then installed the Adaptec. The only way I could
figure out to make the system boot from the Adaptec was to remove the
DPT, boot up once, and reinstall the DPT. Is there any way to tell
which SCSI adapter booted the system?
