Boot from Ultraplex or Plexwriter

I got 2 scsi units from plextor, I got an adaptec 29021 scsi controller, and I wanna know how to install the OS without an atapi drive, for example win2000. I got a bootable cd of win2000 or a bootable cd of win98.

The 2902 doesn’t have a BIOS to support booting from a SCSI drive. You need a 2940Ultra or other controller from Adaptec, Promise, or whatever that has a BIOS. The setup utility for the adapter will then allow you to enable booting from a CD.

So I need to boot froma an Atapi drive and then go on that way.
