Forcing DMA transfer mode

[VeryTired]

Hi i was wondering how do i force my burner to switch to a DMA transfer mode because it keeps on sticking with PIO transfer mode. Also i was wondering where can i get the lastest files for ASPI to download?

thnx

Im probably being stupid here...but do you mean how do you change your burner to DMA mode?
"Start" , "Settings", "Control Panel", "System", "Device Manager", "CDRoms"......highlight the correct drive click on properties and check the DMA box.
May also depend on what OS you have.

i have Xp running,and i did try that...but no luck because it keeps on putting back to PIO...strange..

Set it in the bios.

This is probably your problem...unless you change XP's settings ...XP locks you out of certain abilities... check this out....

This may not relate to DMA settings but once I did this I never had a problem changing things in XP.

what is DMA and PIO?

Sorry for asking this in the middle of your thread very tired.

Windows has quite a large blacklist of devices that claim to support DMA but don't do it reliably. Almost all of them are CDROMs and burners.
Maybe that's your problem - what is the device?

The device is my cd-burner (cyberdrive 16x12x40)

o there are two different transfer mode for system hardwares to use. One is the PIO which is the old version for transfering data. And the Dma is the newer version for transferring data, which is supposely better.

DMA = Direct Memory Access, access w/o heavy CPU usage. Requires special drivers. Faster than PIO.

PIO = Programmed Input/Output, requires lots of CPU usage.

UDMA = Ultra DMA, faster than DMA.

To go along, I would check your BIOS to make sure the drive is able to run DMA. If it's set to PIO, then change it. You might wanna make sure your drive can actually do DMA as well.
