LOL!

Yep, the BIOS can be uber dangerous, but I've used many BIOS' over the years on many different machines. I've messed up countless times, and thus learnt my lessons.

I'm very familiar with the Pheonix BIOS as it seems to be very common.

Yeah, I am lucky, I guess. I'm amazed you jumped right into hardware like that, and if I'm honest, I wouldn't recommend it at all, however, you built it, and it seems, successfully, so kudos! Understanding the software really, REALLY helps when it comes to understand the hardware.

Here's a tip: now, I don't personally do this, because I've never really needed to. I'm so used to settings and aaaall that shizz that it's second nature to me now, but until that happens, I really recommmend you write down all settings you make in the BIOS. Also, should anything go wrong (and it will) then there are a few ways of resetting the BIOS. Incase you don't know, here's some of those ways:

1. Some motherboards support the resetting of the BIOS with simply turning the computer on WHILST the Insert key is held down.

2. Moving the CMOS jumper over and then back. Do this while the computer is plugged in but switched off. I wouldn't do it with the OS booted.

3. Removing the CMOS battery, booting up, inserting the battery back in and saving the now reset settings.

4. Smashing your computer with a ruddy great big hammer until it showers you with beautifully colorful stars... and... um...

So, yeah! Hope that's of use.

EDIT:

Oh yeah! I knew there was another one. Some motherboards have a small button next to or located near the CMOS battery, and when pressed, it resets the BIOS. VERY useful.
