RE: [LinuxBIOS] Asking help for serial output

[Dave Ashley]

CompUSA sells BIOS Post code cards for $50, we bought one and it was
very useful during a certain stage of development. It'd help you before
serial output is working.

They have a 2 digit LED display, it's a little pci card that plugs into
any pci slot. Within linuxbios and all bios' in general during the bootup
process different codes are displayed. You can put in debug statements like
post_code(0xda);
to cause a specific code to show up. So you can tell how far it gets before
something goes wrong or whatever.

Have you tried all the serial ports? Maybe linuxbios is bringing up a different
serial port as the console output one.
Most MB's have more than one.
