Set up processor registers. Select least featured processor as the boot strap processor (BSP). 0Bh G Off G G Hook before the keyboard BAT command is issued. 0Ch G G Off Off Keyboard controller test: The keyboard controller input buffer is free. Next, issuing the BAT command to the keyboard controller. 0Eh G G G Off Init after keyboard test: The keyboard controller BAT command result has been verified. Next, performing any necessary initialization after the keyboard controller BAT command test. 0Fh G G G G Write command byte 8042: The initialization after the keyboard controller BAT command test is done. The keyboard command byte will be written next. 10h Off Off Off R Keyboard Init: The keyboard controller command byte is written.
