How is it failing? It may be that your update kernel is just in
a location your bios can't load. This used to be common in old bios
versions that couldn't go past 1024 cylinders and is probably
possible again with more exotic drive configurations.
It stops at the grub> prompt. And the board is brand new and not out
for that long that I'd call it old.
I also don't consider a SATA RAID on an nVidia controller as exotic.
Those things are on tons of mobos from at least a dozen vendors.
I did remove drives in order to get F7 to install at all and yes, I
added those drives on later, BUT even after doing that GRUB booted
fine. It is just that after updating the system the whole shebang
comes apart for no good reason. GRUB just ought to continue booting
from the same drive and same partition it booted from before...and
it just doesn't do that.
Also, I do not have plain simple IDE drives, but a RAID array on the
nVidia SATA controller that I want to use to boot from. In that
case, when I specify a hdx device it will write the boot loader to
only one of the drives of the mirror array, which doesn't do any good.
If bios sees the drives as separate things, then that's how you have
to install grub, since it has to call bios to load the kernel. On a
real hardware raid, bios will only see the array.
BIOS sees them as one drive. A working F7 sees them as two drives and
as one under the /mapper dir.
I could see this to be a BIOS problem if nothing loads, but GRUB does
load at least so far as that it gets to the grub> prompt. So it is not
that BIOS is confused. It is purely a GRUB issue.

Exactly. I am going to see if it is a kernel problem. Grub really
did work on FC6 and that might have been because it has a different
kernel. I have the last good old kernel still bootable on this f7 and
will try it later.
