I dont want to disturb you with newbie things, but this is a way to start
I am trying to monitor the boot process of a computer, mainly BIOS POST
codes and linux kernel boot process. I know how to do it for the linux
kernel using a serial port, but I am not able to imagine how to monitor the
BIOS POST codes.
I know that almost every BIOS sends them to the ISA I/O address 0080h, but,
how can I get that codes using another computer? I mean, without POST
ISA/PCI card, using another computer connected to it via SMBUS, LPC or
Is there any way to convert LPC to serial and monitor that port?
I want to do this with a VIA P700 motherboard, is this board supported by
the coreboot v3?
Could be easy to redirect BIOS POST codes to a serial port using a coreboot
Thanks in advance,
