I would recommend checking the master/slave jumper settings. Is the
cdrom drive the only drive on the cable? On what positions does the bios
report the drive (primary/secondary channel, master/slave?). changing
DMA settings for the drive may help too. How does Linux recognize the
drive (dmesg + /proc on which, as which drive hda, hdb, hdc, hdd?)
