Enabling DMA in NT

[mithrandir2001]

I've got a Dell OptiPlex using NT Server as my work PC. I ran the Sandra drives benchmark and got a horrible score: 3700. The hard drive is a WD 100BB (7200rpm, ATA100), so this isn't right. Since the CPU usage was pegged during the test, I can guess that DMA is not enabled.

NT Server doesn't have a Device Manager window like Win98 does. I checked under the SCSI Adapters in Control Panel and found the IDE hard drive listed, but the properties window did not have a checkbox for DMA. There's gotta be a way to enable it! Anyone know how?

Try going here (link below) and obtain the dmacheck.exe utility from MS. It will check the current DMA status (which is disabled by default in NT 4.0)and allow you to specify the IDE channel to be enabled.

Hope this helps

Yup, the dmacheck.exe app did the trick...thanks!

Score went from 3700 to 21300!
