Don't recall if you bought a SCSI system or just the controller. The

If you bought a drive from me then it has a nitros9 directory in the
root with the version you are running below it. Inside of that
directory is a script and bootlist directory that builds the boot
disks for you. If you didn't then you are probably finding out that
$25 isn't to bad for a drive and a free installation. :)
If you have HDB-DOS then you will be able to boot directly from the
hard drive at powerup.
Get to the current version of NitrOS-9,SuperDriver and HDB-DOS and
you will have no problems. If not enjoy the challenge.
