Using Post card to diagnose??

Trying to learn how to use a new Post card I just got. It appears to be a decent one. It has 8 LED lights and shows 4 codes such as 0061 Post code. The LED's are +12v, -12v, +5v, +3.3v, CLK, IRDY, FRAME, RESET. During boot all the LED's light but RESET. The IRDY & FRAME are intermittent. The RESET never lights. At end of boot RESET, IRDY & FRAME are out. Right now I'm more concerned with the codes as I'm troubleshooting an old XP machine that will not allow me to install Windows XP. It gets 2/3 installed and locks up everytime. After 6 boots with the card in the PCI slot I got 6 different codes at the end of the boot. I get quite a few during boot but I understand the only one I need to be concerned with is the final one or whenever the card code locks at any particular one code. Here are the codes and also can you explain why 4 code numbers and are the first 2 on left the only ones I need be concerned with. Any help would be appreciated as I'm new to POST cards usage.
0061, 0061, 00AA, 60A9, 6160, AAA8

Doesn't the manual say anything about the codes? You are in the computer business or just doing this for fun? I have built a few computers in my time but have never use the post card. My method is elimination by substitutions.

I'm just a guy who has taught myself through news groups and support forums how to work on computers. I'm actually quite computer savvy today but the post card is something new to me. The manual gives the bios codes but very little other information such as the card has 4 LCD windows showing the codes but the booklet only shows 2 digit codes so what do the other 2 on the card show? [] [] [] [] Consider the 4 previous brackets as each an LCD on the card. The 2 to the left I think show the code but what are the 2 on the right showing? Also the LED lights showing the voltages an such what do they mean and how do you read them. During boot some of them flash on and off and at end of boot 3 of them are unlit. The purpose of the Post card is to save yourself a lot of time while diagnosing your computer. Changing parts out until you find the problem is just more work so I want to learn how to properly use the Post card.
