Well no, but it can work around BIOS limitations.  A lot of IDE
controllers can do 48bit LBA even if the BIOS on the board doesn't do
it.  My Asus A7V used to be limited to 137GB with the onboard
controller, but a BIOS upgrade removed that limitation.

Well if the OS can work around it in your case, then as long as the root
(or /boot) filesystem is entirely within the first 137GB, then the rest
should work just fine too.
