; Common bootsector routines.
;
; This is just a bit file with common code that can be included at the end of
; a bootsector2-xxx.asm file.  Conventions (used elsewhere as well):
;    - _rm    - real-mode function suffix.
;    - _r86   - common real and virtual 8086 mode suffix.
;    - _p16   - common 16-bit protected mode suffix.
;    - _p32   - common 32-bit protected mode suffix.
;    - _p64   - common 64-bit long mode suffix.
;    - _pe16  - 16-bit unpaged protected mode suffix.
;    - _pe32  - 32-bit unpaged protected mode suffix.
;    - _pev86 - v8086 unpaged protected mode suffix.
;    - _pp16  - 16-bit paged protected mode suffix.
;    - _pp32  - 32-bit paged protected mode suffix.
;    - _ppv86 - v8086 paged protected mode suffix.
;    - _pae16 - 16-bit pae protected mode suffix.
;    - _pae32 - 32-bit pae protected mode suffix.
;    - _paev86- v8086 pae protected mode suffix.
;    - _lm16  - 16-bit long mode suffix.
;    - _lm32  - 32-bit long mode suffix.
;    - _lm64  - 64-bit long mode suffix.
;
; The routines uses a custom register based calling convention for all cpu
; modes so that the users can template multi mode code.  To make life easy for
; the programmer all registers are preserved with the exception of rflags and
; any return registers that may be used.  Routines that does not return
; anything will only clobber eflags.
;
; The parameter register allocation order:
;       rax, rdx, rcx, rbx, rsi, rdi(, r8, r9, r10, r11)
;
; When pointers are passed by 16-bit code, segments registers are allocated in
; the following order:
;       ds, es, fs, gs.
;
; The return register allocations are:
;       - edx:eax for 64-bit values in 16 and 32-bit mode,
;       - eax for 32-bit,
;       - ax for 16-bit,
;       - al for 8-bit.
;
; Routines may use other calling convensions will be named differently.
