Absolutely.  Fire up the installer, cpout /etc/fstab, change /dev/sd2a
to /dev/sd1a, and cpin it back.  Or better yet, remove the cdrom drive
from the SCSI chain, and rebuild /etc/fstab with the installer.  I had
no luck with my Toshiba 3501 cdrom or my 8mm tape drive on my SE/30;
you're probably better off leaving all non-hard disk devices off the
SCSI bus until you get everything working.  Then reconnect the cdrom
so you can play Myst when you aren't hacking :-)
