Enabling DMA on DVD drive in Windows ME

[Chatterjee]

Hi guys,

I recently read the Ace's Hardware posting on how enabling DMA on the DVD drive enhances performance a LOT when using software decoding. The question I have is this: A while ago, I tried enabling DMA on a Plextor burner I had and then restarted the computer only to finded that upon loading up Windows Explorer after the computer had restarted, the Plextor burner didn't show up as a drive at all! Because there was no drive showing up anymore, I couldn't "disable" DMA because the drive didn't show up under Device Manager anymore.

Since I didn't know how to get it back, I ended up having to reinstall windows. (Is there a way to get it back?) So I'm kind of reluctant to enable DMA only because I don't know how to rewind back to where I started in case anything goes wrong...

any suggestions?

There's a registry key that tells it to use DMA or not. I have it written down at home, I'll try to post it later if I remember and no one else beats me to it.

Or if you are in a hurry, just search your registry using regedit for "DMA" - there's a ton of keys with that string in it but it's pretty obvious which one it is if you are fairly familiar with that sort of thing.
