IMHO, "root" just specifies the absolute path where to find the kernel
and initrd. You can remove this command if you already use absolute path for
kernel and initrd. It's not necessary and no way to specify in the grub 
config file where the grub (stage files) are installed. Because when grub
loading the config file, it's already running. :-)

The upper level boot loader (in your case, BIOS) should know where the grub 
(stage files) are installed.

Good luck,
