Possible to program something simular with arduino?

I just realized that I have an arduino laying around, and I have some trouble with my motherboard and was thinking to buy a LPC debug card (ASUS LPC Debug Card｜Motherboards｜ASUS Philippines).

But I started thinking if I could do something simular with the arduino.

I have very little knowledge of arduino, but it would be a fun project, could anyone here help me in the right direction? I have no clue where to start. I just plugged the pins in to the digital ports (the com_debug has five). And I just read them as digitalRead, I see the values changes when I boot up the computer. Dunno if it is just a coincidence.

Given there are only five pins, I can only read five digits, which seems strange because the error codes can go up to 99 in decimal.

Have a look at these IMAGES

Once you identify the pinout - there seem to be several types, you can figure out what signals are on the ribbon.

I’m guessing an Arduino can do exactly what you want, but unless you have the protocol, you may spend a few hours reverse engineering the data.
