I have built LinuxBIOS for the amd/serenade target and I get about 600 lines of good output to the serial port, which ends with
Initializing devices...

PCI: 00:18.3 init
NB: Function 3 Misc Control.. done.

POST: 0x00
POST: 0x00
The last line "POST: 0x00" repeats forever. PC80/keyboard.c is trying to initialize the keyboard. The code that is running is
/* empty input buffer or any other command/data will be lost */
while ((inb(0x64) & 0x02))
post_code(0);
The inb(0x64) reads 0xff forever. I heard that the keyboard initialization may not be needed.
How can I fix this? Thanks.
