grep for "int " in /usr/src/linux/arch/i386/boot/*.S
That'll give you a fairly comprehensive list - there's not a lot needed.
IIRC, int 10h for some display stuff
int 16h for keyboard
int 18h for memory test and copying above the 1Mb boundary.
and one or two more.
If you want drivers for Flash cards, give me a shout - I've got some filed
away somewhere for M-Systems (www.m-sys.com) ISA flash boards.
