bios: stub calls interrupt number; simplified bios.ha main interface
Instead of having the bios.call stub calling a function, make it directly call an interrupt that is

Simplify the bios.ha interface and document it.
Next up: implementing a high level drive interface for the BIOS using BIOS interrupts
