3; Common bootsector routines.
4;
5; This is just a bit file with common code that can be included at the end of
6; a bootsector2-xxx.asm file. Conventions (used elsewhere as well):
7; - _rm - real-mode function suffix.
8; - _r86 - common real and virtual 8086 mode suffix.
9; - _p16 - common 16-bit protected mode suffix.
10; - _p32 - common 32-bit protected mode suffix.
11; - _p64 - common 64-bit long mode suffix.
12; - _pe16 - 16-bit unpaged protected mode suffix.
13; - _pe32 - 32-bit unpaged protected mode suffix.
14; - _pev86 - v8086 unpaged protected mode suffix.
15; - _pp16 - 16-bit paged protected mode suffix.
16; - _pp32 - 32-bit paged protected mode suffix.
17; - _ppv86 - v8086 paged protected mode suffix.
18; - _pae16 - 16-bit pae protected mode suffix.
19; - _pae32 - 32-bit pae protected mode suffix.
20; - _paev86- v8086 pae protected mode suffix.
21; - _lm16 - 16-bit long mode suffix.
22; - _lm32 - 32-bit long mode suffix.
23; - _lm64 - 64-bit long mode suffix.
24;
25; The routines uses a custom register based calling convention for all cpu
26; modes so that the users can template multi mode code. To make life easy for
27; the programmer all registers are preserved with the exception of rflags and
28; any return registers that may be used. Routines that does not return
29; anything will only clobber eflags.
30;
31; The parameter register allocation order:
32; rax, rdx, rcx, rbx, rsi, rdi(, r8, r9, r10, r11)
33;
34; When pointers are passed by 16-bit code, segments registers are allocated in
35; the following order:
36; ds, es, fs, gs.
37;
38; The return register allocations are:
39; - edx:eax for 64-bit values in 16 and 32-bit mode,
40; - eax for 32-bit,
41; - ax for 16-bit,
42; - al for 8-bit.
43;
44; Routines may use other calling convensions will be named differently.
