Hope you'll settle for an answer from a simple lkml lurker and not the top
gun.
The address 0x78 points to the floppy disk drive parameter table
described here: http://www.xs4all.nl/~matrix/fdd_pt.html
A list of all the low memory ROM BIOS vectors and addresses can be
found here: http://www.cybertrails.com/~fys/rombios.htm
Cheers,
Sean
