I'm using WinXP (not XPe) with a Cyrix cx5530 / NS Geode SBC. I took out most of the unecessary programs and stopped a lot of services with XP Lite, so XP is running fairly smooth.
Unfortunately, even though I've selected "DMA if possible", the primary IDE channel always reverts to PIO mode. I've tried uninstalling and reinstalling the channel. I've also tried deleting the MasterIdDataChecksum and SlaveIdDataChecksum registry keys. I've also tried changing the cable and removing unecessary hardware, but it's still in PIO mode. Has anyone fixed this before? Is there another cx5530 UDMA driver I can use?
