Well, it's probably not an old BOIS, since the machine is less than 3 months old. I checked the BIOS after the system locked up, and it was enabled. I disabled it, and still couldn't boot until I used the generic kernel. Right now, the BIOS DMA is off, but the ata_dma sysctl variable is still setting to 1. I'll check this out for a while, and see if it works. If not, I'll call Dell for a new HD and cable. Thanks.
