The DMA for your DVD drive is not related to the GF2 at all, it's a factor of your IDE controller. If the DVD-Drive DMA option is greyed out in Device Manager then:

Check the IDE section of your BIOS, see if you can manually set the DMA mode for the drive here (UDMA/PIO 4-5).
Make sure you have the correct Hard Disk Controller drivers loaded (If you have a VIA chipset make sure you have installed the 4in1 drivers (www.viahardware.com has them and lots of useful info). If you do have the correct drivers installed try just removing them and rebooting, they will be redetected (This worked for me once, without loading anything new I got the DMA opton back).
Make sure there are no DOS cd-rom drivers loading (rename your Autoexe.bat and Config.sys to be safe).
Try the drive as the only device on the cable (set as master).

If none of those steps work please post more info about your motherboard/chipset etc.

If you could tell us what motherboard it is, that would be helpful.

Could someone postup the different PIO modes and corresponding data rates.
Please include anything that is the same ie ATA, EIDE, ATAPI (16Mbits isn't it?)
It would be very helpful.

Also, does "Sync Data transfer" help? I think, when i enabled it on my AOpen DVD 1640 Pro it would spinup and spin-down the disc everytime I accessed it. It annoyed the fluck oput of me cos it's not exactly the quietest of drives.
