Thank you =)
I talked to a friend and he said
==================================================
Uninstall:
1) Turn it off, and pull all the power!
2) open the case
3) Ground yourself, and stay grounded the whole time.
4) Unsecure the fan via the attahment clips
5) Find the processor, lift the lever, pull it off
6) Put the 300MHz Proc in a static free bag
7) that's it.
=================================================
In between necessities:
1) Change the FSB to 100
According to the link you supplied to the motherboard picture/info:
Change SW1 to On, Off, Off On, Off, Off
2) Change the clock multiplier to 5.0
According to the link you supplied to the motherboard picture/info:
Change SW2 to Off, On, On
3) Change the CPU core voltage to the appropriate amount. I dont know what the core voltage for that CPU is, you need to find that out before installing.
4) I'm not sure about this one... I would try to leave it as is, then if it didn't boot, I would change the jumper to 2-3.
JPX1
1-2 ---- AMD K6S-300
2-3 *# CPU Type --- Other CPUs
5) Also, what is this set to right now?
SW3(B3, B4)
============================================
Install:
1) Hopefully you still have it unplugged, the power pulled, the case open, and you are grounded.
2) With the lever upright, Place the 500MHz proc in the socket, making sure the pins all line up.
3) Hold you hand on the proc, to make sure it stays seated, and press the lever down.
4) Attach the heatsink onto the 500 MHz proc. Preferably with a thin layer of thermal paste between. My roommate is running his 550MHz K6-2 without thermal paste, and is not having problems. So you can leave that out, it's just better to have it.
5) replace the case cover, plug the power back up.
6) PRAY
7) Hit the power switch.
==================================================
does that all sound okay?
