To the best of my knowledge, disk-based Syslinux expects INTerrupt 0x13 
to be available.  I don't understand why your strategy would not be to 
implement it.  (Or hook it.)  An operating system such as Windows (on 
BIOS) can't really be booted without INT 0x13.

If you want to make a hook without completely starting from scratch, you 
could (perhaps) derive from MEMDISK, which includes dealing with El 
Torito emulation.

Good luck!
