Default PIO - DMA HD Woes

I dual-boot 2k & XP.
One old IBM 22GXP connected to controller on motherboard runs as Ultra DMA
Mode in Windows 2000, but as PIO in XP.
440BX2 chipset Micron, Intel 82371AB/EB PCI Bus Master IDE controller,
latest (HA HA) BIOS.
ACPI Auto Detection both OS's, greyed (can't change).
How to get UDMA in XP?
TIA, Winnie

Go to www.google.com and type "Intel UDMA Driver" in the search window. See
what you can find!

I think you have to go to the Primary and secondary controller section of
device manager under IDE ATA/ATAPI controllers. Double click the primary and
secondary channels, Advanced settings, transfer mode. set to DMA if
available. you will get a warning, just click OK.

Also you can remove the controller and reboot to force a re-detection. XP
will automatically revert to PIO if there are errors detected.

Thanks Dan G, that worked!
Drive now at UDMA in both 2k & XP.
Transfer speeds 70 - 100% faster in XP, even beat 2k on one test!
Hope XP does not "detect errors" and slow it back down (knock on wood).
:-)
