Enligtenment: The grub files need to be <1024 or NewBios else grub is not loaded by the bios, does not run, the end. Once grub is loaded then grub can boot a kernel anywhere.
So grub is loaded by the bios and grub files are typically in /boot/grub which must be <1024 or subject to extension-rules.

RH9 builds a default /boot under 1024, warns you that the bios may not support booting when you overide, uses grub. I've had a motherboad and disk that wont boot (using /boot < 1024 does work), same disk new motherboard does boot. I don't understand! I appologise if my experiences are contary to known science, and confused the issue.
