Minor issue with bootsect.s.
The single instance of the lds assembly instruction includes the comment of
! ds:si is source
...
seg fs
lds si,(bx) ! ds:si is source
...
Is this comment not in reverse order (i.e should be lds
dest,src)................

1. bootsect.S is the source file

2. This is not a comment of i386 mnemonics. This comments the role of
specific register in the following instructions.
BTW, linux-kernel readers: anybody is a volunteer for making the kernel size
counter 32-bit here? This would enable using the simple bootloader for
greater kernel loading... (current limit is sligtly below 1MB)
Possibly some 16/32-bit real mode code mixing would be necessary.

PLEASE don't go there. bootsect.S is fundamentally broken these days
(doesn't work on USB floppies, for example.) It should be killed
DEAD, DEAD, DEAD and not dragged along like a dead albatross.
