I tried to upgrade bios from 1001 to 1003. I finished and all was ok except my cd-rw and dvd were not detected by bios/windows. I then tried to flash to German beta 1004.003.
Same thing. So I flashed back to 1001 and now I have my drives back. Did I miss something? Seems strange when eveything else was detected (hard drives, video,ect). Any help is appreciated.

Win 98 SE
Geforce 3
Iomega cd-rw 12x10x32
Pioneer DVD
