Right click My Computer, Select Properties, Select Hardware Tab, Click Device Manager button. Click on the (+) next to IDE ATA/ATAPI controllers. Right click on Primary IDE Channel, Select Properties, Click on Advanced Settings Tab, Click on the Pull down arrow, Select PIO only.

Um yeah I know how to change thax but it goes right back after reboot. theres a reason and i cant remember

Some have succeeded by using the Intel controller drivers rather than Windows.

I think its not chipset specific. But this is on a VIA board.

I think, but am not positive, that you can set a VIA based board through the bios depending on which VIA IDE drivers you are using.

The bios sees it as udma5 but xp forces slowwwwwwwwww pio mode

Look at this article. The author claims that it is the only way to change it when XP/2K stubbornly won't - http://www.networking.tzo.com/net/howto/win2k/default.asp
