Just out of curiosity, check to make sure you have the latest
firmware for the Teac drive. I recall encountering problems with a
Teac CD-ROM drive on a new motherboard with a fairly new chipset on
the market (this was a long time ago) until I updated the firmware in
the drive. I couldn't boot any OS off the drive, yet it worked fine
on other motherboards. It's worth a shot. You might have similar
problems with any OS on that motherboard and CD-ROM drive.
