Need some way to test if linuxbios is booting correctly. I am debugging and I have reason to believe that my problem is the super io... Does any one know how to get the pc speaker to beep in X second intervals, or some thing that simple, power LED blink... I would like to set up a "speaker beeper" as my payload.
I would also like to try to get the new VGA bios running... The graphics card is built on to the board, just to make life more of a pain. If any one is willing to give me a "How To" that would be of great help.
I would aim at the PC speaker if I could. Usually the PIT (programmable interval timer) which drives that speaker is on the south-bridge, so it should make a very good target for getting output if you are not certain about the super-IO. The keyboard LED is a lot more work, so I would not worry about that. And I would suggest that a payload is much later than you want that debugging to happen.
Unfortunately I don't believe we have an pc-speaker output coded for the LinuxBIOS case. I keep play with the idea of morse code console, using the pc-speaker :) You would not want full debugging on but it might be useful for your kind of scenario.
