RedHat's installer (at least for RH 6.1 and earlier) won't install on a
disk > 8GB unless you make /boot a seperate partition.  This has to do
with an old limitation in LILO where it uses the BIOS representation of
the disk geometry, which only could access the first 8GB. If the partition
where /boot lived was larger than that 8GB, LILO couldn't boot it.

This limitation has since been removed from LILO, but the limitation in
the installer remains in at least RH <= 6.1 and I think 6.2 too but I'm
not sure.
