- EDI bootstrap code (linear address, can be in high memory)

- 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.
