SubjectRe: PROBLEM: dvd-drive no longer works (2.4.20)
Date
Help! I've still got the problem with my DVD drive that I posted a while ago, 
and I've recieved no reply for several days. Does anybody have even the
slightest clue what might be going on? I'm stumped, and any input would be
appreciated.

Regardless of any DMA setting, booting still complains with:
...
00) IDE UDMA133 controller on pci00:11.1
ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:DMA
hda: ST340016A, ATA DISK drive
hdb: ST310232A, ATA DISK drive
hdc: HITACHI DVD-ROM GD-2500, ATAPI CD/DVD-ROM drive
hdd: CREATIVE CD-RW RW8433E, ATAPI CD/DVD-ROM drive
hdd: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error }
hdd: set_drive_speed_status: error=0x04
ide1: Drive 1 didn't accept speed setting. Oh, well.
