-       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.
