Thanks for the reference. Its main claim to fame seems to be that it
is prepared to boot a wide variety of operating systems, using a variety
of techniques that depend on circumstances.
As far as dealing with BIOS limits:
- it still goes through the BIOS for I/O, so it still can't read past
the 8.4 Gb point on any given disk
- within the 8.4 Gb limit, it always uses logical block addresses for
everything internally, mapping those to whatever C/H/S scheme the
current BIOS provides. This means you can move a disk from one
machine to another and have it work, which is not true for bootloaders
that work in terms of CHS addresses directly.
