- 8086 boot code
-
- Code in the following blocks assemble into a binary that is
- suitable to plug into Core words (B350) to achieve a fully
- functional Collapse OS. It is structured in a way that is
- very similar to Z80 boot code (B280) and requires the same
- constants to be pre-declared.
-
- RESERVED REGISTERS: SP is reserved for PSP, BP is for RSP and
- DX is for IP. Whenever you use these registers for another
- purpose, be sure to protect their initial value. Like with
- Z80, you can use SP freely in native code, but you have to make
- sure it goes back to its previous level before next is called.
