Enabling DMA on W2K?

Just curious, how in the world do you enable dma on a cdrom drive in windows 2000? I go to properties in the device manager but there is no dma enable or disable there.... I know that it is there in win98 but not in windows 2000. ANy helpful hints?

Thanks
 
it should be under your controler (in device mananager). If it's a via controller, you might have to enable it when you install your drivers.
 
Yes it is a via controller. I did go to the device manager now and I see that I can select under adnvanced settings the type of transfer mode. It displays Transfer mode as DMA if Avaliable for device 0, and then for device 1 is shows device type, auto detection and dma if avaliable also...... However in the Device 0 it shows the current transfer mode as PIO mode....

???
 
anyone else have any knowledge about this?? I just got my TDK 12x10x32x cdrw installed and wanting to set it up right so that it is the fastest it can be...

thanks
 
I have this problem all the time with my Plextor. To fix it:

Enter Device Manager
Uninstall the "Secondary IDE Channel" (my plextor is on the secondary IDE channel)
Restart
Enable the DMA mode in device manager.
Restart again.
Now you should have DMA.

It's a b*tch, but it works. You may lose DMA once in a while...just repeat the steps above. I think TDK drives are made by plextor.
 
I read the article, still no luck.... Someone has an answer to this problem. I emailed TDK, hoepfully I will get a response from them. Just about ready to install 98 back on, but I like w2k so much better!

uuuuuuuuuuuurrrrrrrrrr
 
Isnt the TDK the same as the Plextor/ZIP? If it is, could have to do with the other AT'ers are saying about moving a jumper on the drive to enable udma? In win9x, it doesnt seem to matter in regards to setting DMA in the OS, but I wonder if it matter in 2000.
