DMA Disable

[Guest]

I am running a CD/DVD record program (Roxio) and continually get buffer underrun errors. I tried slowing my recording speed, disabling all other programs, etc... and the error msg says to try disabling DMA. How can I do that?

Thanks in advance
John

To disable DMA right click My Computer, click manage. In the window that
opens, click device manager in the right pane. Expand the IDE ATA/ATAPI
controllers listing, right click on Primary IDE Channel click properties, in
the properties window that opens click on the advanced settings tab and
change the Transfer mode option for each device listed, click ok. Rinse
lather and repeat the above steps for your secondary IDE channel as well.

It is not *usually* a good idea - more often you need to enable it.
But Control Panel - System - Hardware - Device Manager and in IDE
ATA/ATAPI Device Controllers, look for either Primary Channel or
Secondary, depending on where your drive is connected; double click, and
in the Advanced page - Transfer pane for the device, select PIO only.

Do *not* put Primary - Device 0 into PIO; that is the main Hard drive
and doing so will slow it down.

More to the point, have your hard disk well defragmented so that the
heads do not waste time dancing around to find bits of files.
