It was between 1.0A and 1.2, but when I'm not sure. The problem is
that the BIOS lies about what memory is available. The boot loader
tries to use the memory, and things blow up. Trying to figure out
what memory the boot loader can or cannot use is a hit-or-miss
proposition. What will work on one computer will not work on another.
The problem is compounded by FreeBSD's original boot loader design,
the 'BTX' junk, which tries to create a generic operating environment
(including changing the vector table) for the various boot loader
stages. The forth code doesn't help matters, either. It just makes
things even less understandable.
Can we not just adopt some other boot loader which doesn't make
such pathetic predictions ? Somehow, the idea of heuristical
decisions at boot stage are really not pleasing. :-)
