Default motherboard help. Compaq Presario 5700T Motherboard

I brought this motherboard on ebay with out a book. I need to know how to
set
up the pin's or wire for the power led and keys. I don't want to burn the
motherboard from just guesting at it. If anybody could help me that would
be
great. This is what I have.
This is my personal Compaq Presario 5700T Motherboard (136109-102) with
the
Processor and memory still installed. The processor is Pentium III 700mhz
and
there are 3 - 128mb Pc100/133 modules.

You aren't going to burn the motherboard by guessing at it. Power and reset
are momentary contact. Either they are connected, or they aren't. You
can't "short" it in reverse.

The LEDs connections can be reversed. Three things will happen if you
guess:
1) Nothing (wrong pins)
2) Nothing (right pins, but reversed wires)
3) LEDs work correctly

Having said that, you shouldn't have to guess. Most mainboards are marked
somehow, though the print is microscopic and often abbreviated, such as
2-point type reading "pwr_led" with little + and - signs. That would be the
Power light on the front of the case, and the +/- shows which way to connect
the wires. At worst, if the wires aren't marked, you've got a 50/50 shot at
it, so you'll get it right in 2 tries or less. -Dave
