Where do I enable DMA in ME?

[CrazyHelloDeli]

Im getting constant buffer underruns no matter what I try to burn with my Plextor 16/10/40 and the manual says that I need to enable DMA on my DVD and Plextor to stop the problem, but it doesnt give me the check box in Device manager! I have no way of telling if its enabled already of if I need to enable it, how I can.

Im using Adaptec software 4.0 that came with the drive if that matters at all, and no I dont have the money for Nero ATM...

It's in the same place as all the other Win 9x operating systems. If you have your CD-RW and DVD drives hooked up to a PCI IDE card or one of the extra 2 IDE connectors (High Point or Promise) on your motherboard instead of one of the IDE controllers that's integrated into your chipset then you might not get the DMA checkbox. I don't know how you'd tell if DMA was enabled if you don't see the box though...

Doesnt the Plextor have a jumper on the back to switch from PIO4 to DMA33? My TDK rebadged Plextor does... check your manual or look in the back. If you installed the VIA DMA drivers as "miniport" you wont see a DMA checkbox, you have to use "DMATool" to switch the modes per device. I recommend you install as VXD/VsD since miniport uses more CPU cycles.

The jumper trick is for the 12X plextor, I'm not sure if it works with the 16X (I think it's already UDMA33)...

This is on a P4 1.7Ghz and Asus P4T Mobo. And I still cant seem to find out if DMA for my CD ROM's are enabled.

What kind of sh!t is that? If you can't help you do not have to post!

by any chance did you install the intel storage drivers??

this comes up all the time

Once again: If your device(s) are hooked up to ANYTHING other than the legacy mobo IDE controller, and THE DRIVERS ARE PROPERLY LOADED for that ATA66/100/ (RAID), then you are IN DMA. ATA66/100 CANT BE ANYTHING ELSE BUT DMA BY DEFINITION. Windows will grey out your checkbox in this case, you have no choice.

The legacy mobo ide controller CAN BE SET to DMA ATA33, IF YOU WISH. In this case windows will allow the check box.

If your non HDD optical device has big problems on the ATA100 bus, then it may not be compatible with these transfers - like when you put CD/CDR on same cable. The answer is to move one/both to the legacy controller.

<<<cant afford Nero>>>

Nero has a trial 30 day vers on their website. Might be worth it to see if that solves it.

I assume that since Adaptec 4.0 came with your burner, its the last update 4.02 3XXX (from my memory)
