GRUB, Savedefault & MBR

[lode leroy]

The first sector (512bytes) of the hard disk contains the stage1 image 
(400bytes) and the MBR (4x16 bytes).

The stage1 image contains a pointer (stage2_sector) to the first sector of 
stage2 (which resides in the filesystem, and can be ANYWHERE on the disk, so 
not necessarily on the first 100 sectors!)

The first sector of stage2 contains pointers (blocklist_default_start) to 
the other sectors of stage2.

The options are stored in the first (and second) sector of stage2.
