[syslinux] [PATCH 0/3] v2: mbr: Ctrl-key press forces load from first hard disk

[TJ]

Version 2 of these patches includes optimisations suggested by H Peter
Alvin to save bytes:

  * Use memory-mapped I/O register to read keyboard shift flags
  * Don't reload DX from memory; move immediate byte to register

Tested using mbr.bin.
