Scancode Set 3 Mapping Table



OVERVIEW

Enables a PS/2 keyboard with scancode set 3.

Caution: this package is not necessary for most usual keyboards. In
particular you don't need it as long as you're using your keyboard
flawlessly. If you've got an unusual keyboard (e.g. HP UNIX keyboard)
which doesn't work well, you may better try this.



REQUIREMENTS

o BeOS R4.5/R5 x86
o PS/2 keyboard with scancode set 3

Following keyboards are supported.

o US 101 keyboard
o European 102 keyboard
o Japanese 106 keyboard
o HP A2880A Japanese UNIX keyboard



INSTALLATION

Copy AT_Keyboard_Info to ~/config/settings and reboot. Note that
HP A2880A requires a custom keymap.

HP keyboards may not generate break codes by default and the system
may behave as if keys once pressed would remain pressed (e.g. all
alphabet keys you press will turn into control codes after you once
press the Ctrl key). To solve this problem you need to write in
UserBootscript as follows:

	poke > /dev/null << END
	outb 60 fa
	inb 60
	quit
	END



CAVEATS

Following keys are ineffective.

o SysReq (Alt+PrintScreen), Break (Ctrl+Pause)
o henkan, muhenkan and hiragana keys on Japanese 106/109 keyboard
o left/right Windows keys and Application (Menu) key
o power management keys (Power, Sleep, WakeUp)
o other exotic keys ("multimedia" keys, "Internet" keys etc.)

Following keys show unusual behavior.

o F9 eats the next key (because its translated break code is 0xE0).
o Keypad "-" acts as SysReq (because its translated make code is
0x54). That is, Keypad "-" + "d" invites you to the kernel debugger.
