I'm sorry, but I never could figure out GRUB so I use LILO.
I do see this:
Filesystem type is ext2fs
but mount reports /dev/sda1 (is that / on the sata drive?) is ext3,
so that must be the IDE drive it's attempting to boot. I think
that hd0,0 is the master drive on the primary controller, and
hd0,1 is the slave, etc. If so, then I don't know what will be
the designation for sata0 and sata1.
When I've installed the 2.4.26 kernel with my sata drive, it is
recognized at /dev/sda but when I installed 2.6.7 it was then
changed to /dev/hde so I couldn't get it to boot. Check out
