    I've read several articles but I'm still somewhat confused about this DMA feature in device manager under Disk Drives.

    I checked the DMA box under properties and couldn't reboot, had to scanreg/restore to boot. Bios option for UDMA is enabled. But what else do I have to do to set up for this? My BIOS may need an update. Would this make a diff?

    AMD k6-II @500MHZ
    98SE
    Fixed FAT32
    Generic IDE Type 47

    Thanks

    your hard disk is already set to UDMA so if you try to make it DMA you will have to disable the UDMA (ultra DMA)

    Thanks for the response. So does that mean my Hdd was already utilizing DMA? I'm not sure I understand. What is the difference betwen DMA and UDMA?

    Thanks
