; 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.
