Yeah, I'd have liked to avoid that too, but some compilers will complain
about pointer arithmetic logic, unless you specifically use uintptr_t.
But, considering your other very valid point, let me see if I can work
something better here, that

Initial support for sector size >512
This set of patches add some support for sector size >512.
Currently it fixes extlinux, MBR for GPT and ext partitions.
Other code is unaffected.
This set of patches has been tested on a read Dell machine running a beta
firmware.

unload memdisk+FreeDOS => local boot
.... The memdisk 'TSR' can
then restore those vectors later, along with fields from the BIOS Data
Area. This effectively restores the machine to its previous state and
allows one to boot from local media.
additions to memdisk/setup.c
----------------------------
I added 4 data fields to the patch_area struct that is set up for the
memdisk TSR.
1. the BIOS_EQUIP word from the BIOS Data Area
2. the BIOS_HD_COUNT byte from the BIOS Data Area
3. a copy of the first 128 interrupt vectors (0-7Fh)
4. a checksum on the upper 128 interrupt vectors (80h-FFh) to validate
that they are unchanged when we...
