HDD and DMA

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

DMA of my hard disk is disabled i.e. it's in PIO mode.
It used to be DMA now even if i select DMA if available it stays in PIO mode.

Event Viewer:

Event Type: Warning
Event Source: atapi
Event Category: None
Event ID: 26

The driver has detected that device \Device\Ide\IdePort0 has old or out-of-date firmware. Reduced performance may result.

It went to PIO mode when recently I connected my HD on another PC running Win98 and now in my PC (WinXP) the DMA has went out although While booting my motherboard i.e. BOIS shows UDMA, mode 2 for both my HDD and CD-ROM.

The funny thing is that, When my HDD was on DMA mode, i tried many times to set DMA for CD-ROM but nothing worked.
Now when my HDD can't use DMA mode my CD-ROM got UDMA, mode 2...

Can anybody help??

HDD is PrimaryMaster and CDROM is Secondary Master
