At times in the past there was a race between BIOS support for large 
disks and hard disk size, and BIOS boot code could not reach the far 
sectors of the disk. This even leaked into Linux sometimes, IIRC: LILO 
would use BIOS calls to load the kernel, and it would work on the 
original install because kernel was dropped on disk early on and end up 
in the low sectors, but would fail on kernel upgrade when the kernel 
blocks would end up in the filesystem areas beyond the BIOS reach.
