OK, two things: I did not change any BIOS mapping or drive or boot sequence. I install F7, GRUB installs fine, GRUB boots fine, I install updates => GRUB is broken beyond repair.

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.

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.

Les you have bios on the brain. My 1994 bios works fine with 2007 hard drives. You are trying to protect the grub people I think. It isn't grub but it could be a kernel problem. I might boot to my old kernel and see....
