Well, there are workarounds (various BIOS extensions). But usually, it
is wise to stay bellow 8 gigs on partition you boot from, because INT13
is standard way for boot loaders to comunicate with BIOS. Some older
software (ancient software?) have even more serious limitations (like
~500MB). I know that LILO has option to use LBA32 addressing (if BIOS
supports it), but I'm not sure about Grub.
