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 serial?
There are some POST cards which convert the POST codes to serial, but they are really expensive (>50 EUR).
Is there any way to convert LPC to serial and monitor that port?
You can convert LPC to usb-serial (a virtual serial device which appears once you plug in the USB side into the monitoring computer) with the Artec FlexyIce (formerly known as the Artec Dongle). The FlexyIce is also usable as LPC/FWH ROM emulator and ideal for firmware/coreboot development.
Could be easy to redirect BIOS POST codes to a serial port using a coreboot implementation?
If you have coreboot, you don't need POST codes because you get detailed messages (similar to Linux kernel messages) from coreboot on the serial port.
