I have a new Dell Optiplex 240 running Win2k. 2gig CPU with Intel 82801 chipset.

What is the correct IDE mode for a CD-writer in this setup?

In the windows device manager, the properties for the IDE channel connected to the Cd-writer shows the transfer mode as PIO. The Cd-writer is the only device connected to the secondary IDE channel.

It seems like the mode should be Ultra DMA (like the Primary channel which connects to the HDD).

Are the high speed ATA modes supported by Cd-writers or is that just reserved for HDD's

thanks in advance...

What mode, depends on the CD-RW drive itself, and the software you are using.

Many CD and CD-RW drives support UDMA-33 mode.

You may need to manually set the DMA mode in BIOS settings in order to enable it for the CD-RW drive.
Then, you can enable DMA mode in device manager.

Be sure to check which mode your CD writer software recommends that the drive be set for.

1. Make sure that the CDRW jumper is correct for its connection on the IDE cable. Dont use Cable select.
2. Go into Bios and enable IDE = auto on all columns for IDE #2.
3. Reboot, go into Bios again and see what Bios detected. This is usually right.
4. Use same settings in 2k as in Bios.
