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
