my box: t-bird 900/asus a7v kt133/win me

my problem: can't set dma in windows me (when i tried it, my hdd disappeared from device manager)

what i did: i tried 4-in-1 drivers, but i can't get that "atapi vendor support" (or something like that) dialog. so i set the bios to udma4 and things seem to work, but i'm not sure (the hdd is still on device manager, at least...).

my hdd supports udma5, cause the bios auto-detects it. how can i enable it?

should i try IDE Busmaster (580_2150.exe )?

any help would be appreciated.

By default, windows will enable DMA support for all your compliant devices. If your bios is detecting your drive as UDMA 5 then it should be enabled, however, the difference between UDMA 4 and 5 is probably negligable considering IDE drives are only now starting to sustain 30 megs/s, but that's still only UDMA 2.
