Vern,

Don't recall if you bought a SCSI system or just the controller. The 
TCC512 is no longer supported because it is replaced with SuperDriver.

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.

Regards,

Mark
