When the rescue disk runs, it finds your current installation and mounts it 
under /mnt/sysimage

type 
#chroot /mnt/sysimage
then
#grub-install /dev/sda1 
(assuming your master drive is the first SCSI drive)(run fdisk -l first to 
check what drives can be seen.  Check the contents of /etc/grub.conf to see 
if that gives you the clues.)

However, this assumes that all that has happened is that the boot record has 
somehow been corrupted.  I'm not to certain this is the problem.  However, I 
don't *think* you can do too much damage here, since the command would 
normally just write a new boot record to the boot disk.  The worst that can 
happen is your grub.conf wouldn't match with your current partitions.

Others may correct me here. <grin>
