-AX=000Dh [2.08] Cleanup and replace bootstrap code
- Input: AX 000Dh
- DX derivative-specific flags (see previous function)
- EDI bootstrap code (linear address, can be in high memory)
- ECX bootstrap code length in bytes (must fit in low mem)
- EBX(!) initial value of EDX after bootstrap
- ESI initial value of ESI after bootstrap
- DS initial value of DS after bootstrap
- Output: Does not return
-
- This routine performs final cleanup, then takes a piece of
- code, copies it over the primary bootstrap at address 7C00h,
- and jumps to it. This can be used to chainload boot sectors,
- MBRs, bootstraps, etc.
-
- Normal boot sectors expect DL to contain the drive number,
- and, for hard drives (DL >= 80h) DS:SI to contain a pointer to
- the 16-byte partition table entry. The memory between
- 600h-7FFh is available to put the partition table entry in.
-
- For PXELINUX, if the PXE stack is not unloaded, all registers
- (except DS, ESI and EDX) and the stack will be set up as they
- were set up by the PXE ROM.
