to enable DMA?
 

Is the below advice good for a PI PC?
I have a 3.68gb hdd.

"You can enable DMA by
going to Device Manager under System Properties. Under
the list, find the drive you want to enable for DMA.
Right click on the item and hit Properties. Click the
Settings tab and check the DMA box. In order to work,
your BIOS must support DMA and you must have the right
bus mastering drivers installed. These drivers usually
come with a new motherboard or machine."

how do i know which bus mastering drivers I have or if BIOS
supports DMA? The DMA box is not checked.

Check the box, restart. If everything works OK, and you go back and the
box is still checked, your drive, controller, and BIOS all support DMA.
Otherwise, Windows will uncheck the box on its own.

Hello,
In order to find out whether your PC accepts the bus mastering, all
you have to do is check out your motherboard and find out what chipset
it uses. Normally it's the circuit that says "PCIset". If this circuit
is Intel and has FX,HX, VX, or TX as its suffix (i.e., the one on most
extant motherboards), your PC can benefit from bus mastering.

The info is a smidge out of date. The Intel TX, VX, and HX chipsets were
circa 1997/98, and FX was 1995/96. Of those, only TX was capable of UDMA,
the others could do multiword DMA only. All modern chipsets (other brands
included) since then do bus mastering and UDMA of various speeds.
