DMA Problem w/. WinXP.

[IceT]

My XP box has been running fine for months, however, I just noticed a problem last night. I couldn't turn DMA back on for my DVD ROM drive which is a secondary master along with my burner, secondary slave. Even though I selected "use DMA if available" for my DVD, after a restart, it's still PIO mode. However, my burner still have DMA enabled as well as my two HDs on primary master/slave.

I tried installing the latest ViA drive, still, no go. No DMA for my DVD.

Please advise.

try to enable it in the BIOS

My BIOS detects both drives as ATA/33.

Like I started noticing that the DMA wasn't on for my DVD. But before, the DMA was enabled for all drives no problem. I haven't added/removed any hardware lately.

in your bios try setting all the drives to none except for your boot drive...

I tried your method, setting UDMA disabled for my optical drives. Still, no DMA for my DVD but for my burner.

I don't know why, seems so strange to me.

Did you figure it out? I'm having the same problem right now with my burner

you could try removing that 2nd ide channel in device manager, reboot & windows should redetect/reinstall it with hopefully both drives using dma transfers!

are you using ata 100 or 133 cable's?

Try going into Bios under "Intergrated peripherals" and look for secondary master & secondary slave , then select ATA-33 or 66 (whatever the correct ATA speed is for your drives)rather then auto.

Yeah, got it figured out already. Did the same as Bacillus say. It works for me🙂

I'm using ata-133 rounded cables from svc. I tried unistalling the drive and rebooting, and disabling everything in bios. I don't have the option to set the transfer speed in bios, only to choose whether or not to detect dma. I still can't get this to work. Any other suggestions?
