I don't see that DMA error. After poking around my machine and the web, it seems the speed warning message is created because my machine doesn't appear to have an 80-wire IDE cable connecting the hard drive to the motherboard. Since both the drive and the hard drive are ATA133 compliant, and it's a laptop so the IDE cable will be about five inches long, isn't there some way I can make it think there's an 80 wire cable present? The bios isn't that helpful, and adding "ide0=ata66" to my GRUB command line doesn't do anything. Attempting to set the drive's speed above UDMA2 still results in the speed warning. The actual IDE controller is a SIS963. -- http://www.piku.org.uk - Outdoor Photos: http://www.piku.co.uk
