Then the same will work in your grub.conf file, but you have to "setup"
grub onto the MBR where the BIOS will read it.
To do things in the usual way on a multi-disk system, you'll have to:
a: Work out what disk the computer will boot up to, and "setup" grub on
that one's MBR so the BIOS boots up grub, and grub takes over.
If you have a multi-disk system where some of the drives are
removable ones, you may have to set grub up on more than one drive.
b: Work out what the computer thinks will be the boot partition
(whether it's hd0,0 or hd1,0, etc.), which is *grub's* "root", and
you'll set that parameter while doing grub setup, which grub
uses to load its files to start booting an OS.
e.g. In the grub shell:
Command to tell grub where /boot is: root (hd0,0)
Command to setup the MBR: setup (hd0)
Command to write the changes: quit
(That's an *example* of how it *could* be set, adjust the actual
drive parameters to suit your own system.)
Read the grub documentation, ignore the scanty man file there's much
more information elsewhere. Look at the info file, or their website.
