Motherboard specs

I'm looking for tech specs for a Dell motherboard the type and rev are SE440BX3; rev A01; AA number 722394-110 and board number E139761 with all this information it should be quite easy, however I've searched Intel and Dell as well as some other sites. The closest I've been able to find is Intel's SE440BX2. This is very close however the board I have only has one ISA slot, one seriel out, and the pins for LEDs and switches are not in line, but there is a block covering pin holes 1-8

There is also another barcoded number on the board000535T-12464-9A6-0159. Unfortunately I do not know where to hook up the power and reset switches.

If someone can help I would appreciate it.
