5.4.3 8041 to 5TO-8105 Scancodes and Commands
The keyboard (emulated by the 8041 ) sends scancodes and commands to STD-BIOS driver
system. The scancodes/commands are read from the 8041 Data port (Input Port 60H). Table
5.22 lists the keyboard codes returned by the keyboard. As with the controller commands, some
of these codes are initiated by 8041 interface driver and not the physical keyboard on the HP-HIL
link.
