Hello all, I've recently got a a DELL 09439 motherboard for a Pentium PRO system I'm building. I'm trying to find the manual/specs/schematics for this one so far I had no luck can anyone point me to right direction ?
attached are the tags found on the mobo as well as the mobo itself.
Thank you in advance
DO NOT PLUG INTO, your with ATX power supply, you need adapter cable first!
Needs ATX to DELL adapter cable, I bought couple while ago.
Tricky to find but I did find it again.

The AA sticker looks like an Intel board sticker. And appears to be the Intel 450KX chipset.
probably like this: https://theretroweb.com/motherboards/s/dell-d … mension-xps-pro___

Yea DELL is a giant throbbing knob-end for doing that ATX thing.
MANY MANY "oem" companies will rely on someone else to build their boards. Intel made motherboards for anyone and let them put their own coat of paint on it. ASUS made motherboards for HP for over a decade, as another example.
It is a mistake to think you can solve any major problems just with potatoes.
Thank you for your information, although I find it a bit strange on the front end connectors, that the board does not have a power on marking...it has a rest, led, speaker and sleep ? ....does anyone know ? I'm trying to find a manual or a diagram layout of sort...
The power connectors and fan connectors pinout for the Dell Poweredge 2100 look the same.
Looking at that connector. between the base OEM config and the dell... I would wager highly, if you were to move the ATX connector on the motherboard to the other side, it would likely be compatible with "standard" ATX power supplies.

Not all can do this soldering skill, if you are up to this, you can move the 20 pin power connector over and use standard ATX PSU.

That's.. exactly what I said?
Anyway, worst case scenario, 20- pin atx connectors are jelly-bean parts. So as gon as you don't mess the board up, you can try multiple times. Just take your time.

and how about this connector here ?
can it be ignored or is it required in order to work ?
When using Dell to ATX adapter cable, yes that is used with this, why did you not see this in this ebay link?

Other option but need soldering work, if you can or someone else do it for you.
If moved the 20 pin power connector over to ATX standard pin out then you can use standard ATX power supply without the 3.3v 6 pin connector.

That's what I was asking, since I live in europe, the adapter will cost about 30 bucks (customs and import taxes) where its price is about 9. So I think I'll go with the solution of moving the ATX power cables.

Are we 100% sure that these pinouts are the same with my motherboard ? is there a way to check my motherboard's pinouts ?
You could make your own adapter. Buy a 20 Pin Motherboard to 24 Pin ATX Power Adapter and rewire the 20 pin side using the 'staple method'.
That would cost about 5 or 6 euro.
Ok, cheapest way is get the motherboard to a electronic repair shop and have them move the connector. Old school shop is best and you will able to use standard ATX 20 + 4 pin power supply. Most of ATX power supplies have a 20 +4 connector that separates when you don't need the 4 pin connector.
Even you made the cable adapter, you need to get 6 pin connector too which is a hassle in your country.

Lucky for me I can get some and I do have a spare 6-pin connector from a fried old PSU.
Thank you
Perfect! Smart.

Yes there is a way ! Use a DVM set to ohms and check the pins on the ATX style connector to known voltage pins in the ISA and PCI slots. The Grounds, +5v, +12v, -5v and -12v should be easy.
https://old.pinouts.ru/Slots/ISA_pinout.shtml and https://pinoutguide.com/Slots/PCI_pinout.shtml
The 3.3v should also be fairly easy to trace.....they should be a few ohms or less for each.
