Nova 32 bits on older Pentium 4 computer.

[Paul Dufresne]

Ah no, I think I can guess (all my understanding is rather fuzzy).
This 0-1000 thing, is my old real mode interrupt table (256 entries,
of 4 bytes each).

Well, I am surprised to see how this x86emu can be coded in user mode.
But I find strange that so much assembler seems to need to be
emulated, I was expecting that vm86 mode would make all that
unnecessary.
