Subject: Using GRUB2 with CoreBoot (formerly known as LinuxBIOS) 2/4: Keyboard controller
Date: Sat, 12 Jan 2008 17:53:42 +0000 (UTC)	[thread overview]
Message-ID: <fmaur6$kp5$2@ger.gmane.org> (raw)

Hi,

second installement of my mini-series:

The AT keyboard driver assumes that the keyboard is set to scancode set 
#1. It seems like many keyboards use set #2 (or even #3) by default now, 
and some 8042-emulating chipsets don't enable translation (to #1) by 
default. The BIOS then enables it to support the legacy compatibility the 
PC architecture is famous for - but CoreBoot doesn't.

http://osdever.net/ has some information on programming the 8042 (without 
BIOS calls), incl. how to configure the scancode set you want to have.

Also, 0x01 is the scancode for ESC. I didn't look if there's a special 
case for escapes, but a simple "\e" instead of "\0" at that code point 
might help.

Regards,
Patrick
