You need to check your superio and southbridge doc to enable serial port as early as possible. with the help of post_card, or HDT you could know which line is reached and if the pci conf register is set correctly.

Hi All,
I am a novice in LinuxBIOS. I am porting a system now. I see the linuxbios code with many "print_XXX" code. How can I see these messages during post stage?? It's hard for me to check the bug point using post_card and not efficiency.
Thanks for your help.
