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.
now that's a cool idea, Eric, I didn't know you knew morse code!
Not very well. The idea originally came from Alan Cox with respect to the kernel. I have simply been mulling it over for a while. With the realization a couple of days ago that the PIT is easily accessible makes it that much more attractive.
I think morse code would actually tie in better with the post code infrastructure than general console traffic. That would keep the volume of data low enough so as to be meaningful. Even if you did not know morse code.
How about for the failure case: ... --- ...
:)
Except that usually the failure case does not print a message.
But a boot sequence that when like ----- .---- ..--- ...-- ....- ..... -..... --... ---.. But never got to ----.
Could be pretty telling.
