I also suspect What Jean-Marc said is the problem. I'd recommend completely disabling everything in the old ATA section to ensure it doesn't attempt to control any devices, while building the PATA driver into the kernel and using root=/dev/sdXN in the grub parameters. The module approach should also work, but I always get a little suspicious that it might build something else into the kernel unnecessarily that causes problems. > My next step is to completely rebuild the kernel, using the config built > into the distributed kernel source, making only the necessary mods for > the box's hardware needs.

If the pciutils version on the CD is too old, `pcimodules` might work instead. -- Thanks, Donnie Donnie Berkholz Desktop project lead Gentoo Linux Blog: http://dberkholz.com
