2000 set CD/DVD DMA Unattended

[Joe User 99]

We are deploying some new Dell GX620's with DVD's on Windows 2000.

The problem is that Windows 2000 defaults the DVD to PIO mode rather than DMA.

This causes audio issues.

Anybody know of a way to enable the DMA for the DVD (Or all IDE controllers) without requiring user interaction? I know how to turn it on, but I need it done during the unattended install somehow.

Either a script, or commandline utility, or something.

Any suggestions are appreciated.

TIA
