Here is the relevant compatibility code relating to boot-compat.b. The sole
difference between boot-compat.b and boot.b is that boot-compat.b is produced
with BROKEN_BIOS_COMPATIBILITY defined (so it won't boot NT4).
_main:
#ifndef BROKEN_BIOS_COMPATIBILITY
cli ! NT 4 blows up if this is missing
#endif
I expect that your MBR boots NT4 and as I believe that the problem is the
laptop can not use a boot loader that works with NT4 I think it's likely that
your code will not work with it. However I don't know for sure as I can not
spare the time required to read the code at the moment.

Another option that probably hasn't been considered. Boot up dos and run
"fdisk /mbr" to put the DOS MBR on it. I'm certain that no-one has released
a PC which is unable to boot DOS... If LILO is then installed to /dev/hda2
and /dev/hda2 is marked as active in the partition table then DOS should load
up LILO and things should be fine.
