Go into Device Manager and expand the IDE ATA/ATAPI controllers then look
at the properties for the Channel where your CD-ROM is attached.

Go to Control Panel - System - Hardware - Device Manager

Look in IDE ATA/ATAPI devices, in the Primary channel or Secondary
channel, depending on which it is connected to. Double click, look on
the Advanced page, and make sure that 'Use DMA if available' is selected
as the Transfer mode for each device

If it *is* selected but the drive is still showing Current Transfer mode
as PIO, then you need to highlight the master controller (immediately
above Primary Channel) and take Action - Remove. OK out, close down,
power off and reboot to let PnP start over. This can happen if there is
an error burst - the system falls back on the slow but safe PIO and
sticks there.

Note that all that is if you use standard MSoft drivers - if you use
third party ones, like VIA 4 in 1, or Intel Application Accelerator, the
information will not appear, but those will be assuming DMA anyway
unless it is turned off in the BIOS
 
Hi Alex,

I'm hoping you can help clarify something.

are you saying that if I have the VIA Master IDE
Controller installed, then even though in driver it seems
to have the standard MS driver isntalled, the VIA IDE
controller is doing DMA 5 on my hard drive, though mine
is stuck at DMA 2 according to Device Manager?

Thanks in advance.

or, if my VIA IDE Controller is installed, should I see
IT as the driver under 'Driver" in Device Manager? Is
that what you meant by "info will not appear, but..."???
Thanks again
