CD-ROM drives usually show in BIOS using their factory names such as:
TSS corp CD/DVD device
And similar...
In some other BIOS editions it will simply say CD-ROM or something similar...It really depends on the BIOS.
Are you sure that there isn't absolutely ANYTHING what would point to the CD-ROM drive?
Also is your CD-ROM device working properly in Windows and is it connected properly to the motherboard (power cable and data cable)?
