mystery motherboard

[lido]

i have a motherboard out of a huge gateway tower.(server?)
the case had no power supply when i got it. gateway's not sayin' anything about it
because i don't have the numbers off the case.
don't have a bios i.d. and here's why; i don't want to power the board up until i get more details
on whether or not i can try it with a 166mhz, 66mhz bus pentiun cpu.
need to know if it wants edo ram or regular 72 pin ram(parity or non-parity)
and what the jumpers located next to the board voltage jumpers are for.

here are the details:

>cpu socket---------------------------socket 7
>?board i.d. numbers,stenciling on the solder side--------L-9725-8 ml-1 94u_0
>other letters on the solder side-----"C E"
>pci chipset--------------------------430hx pci chipset
>?ram slots----------------------------four 72 pin, two 168 pin
>isa slots----------------------------three
>pci slots----------------------------four
>?cpu jumpers-------------------------50, 55, 60, 65, 70, 75m
>?cpu core voltage jumpers------------2.5, 2.8, 2.9, 3.2, 3.5v
>board voltage jumpers----------------3, 5v
>primary, secondary ide ports
>big chip i.d.'d as "burroughs"
>amibios 586
what i figure are the board i.d. numbers are hard to figure
because i have not been able to get any hits on anything like them.
i'll appreciate any tips i can get.

Here's some info that may help:

a little blurb on 430hx chipset:
http://www.motherboards.org/subpages/chipset-05.html

I have a Pentium 166 non-MMX. I used this chart
http://developer.intel.com/design/pentium/qit/database/SY037.htm

to find out the voltage, etc. From the numbers you have, it looks like it would work at the 3.5 cpu core voltage.

Good Luck http://www.sysopt.com/forum/smile.gif

If your 166 does not say MMX on it anywhere, it should run at 3.3v, if its an MMX, it should run at 2.8, if thats what you are asking. If in doubt, set it to 2.8v, and if it won't run, its not an MMX.
