Since this is a Dell computer, this is a Dell OEM board.  The manufacturer may be Intel or some other mobo manufacturer, but they have probably made modifications to it at Dell's request.  This would make it a non-standard board.
If this is an AT type board and case, you are better off purchasing a barebones system from a place like and scavenging whatever parts you can from the old system.  That may be the best idea anyway since this is an OEM board.
Find the board's FCC ID and look it up here:
Go here and enter the service tag number of your system. You will then be able to get more information on what your exact system is.

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Slink9 and jlauster both provide valid info but from what Dell says a limited upgrade should be possible. I believe this mainboard will support a PIII to 850mHz(8.5X100) and 768MB PC100 SDRAM(3slots).I hope this link works for you:

Thanks to all who helped.

You can easily identify a motherboard with Sisoft Sandra software.
You can download a trial version here :
or here :
But you have a xps T500 ..
You must have a intel motherboard, name of motherboard is SE440BX3. It's an oem version of intel SE440BX2.

It's a slot1 motherboard.
You can find found information here :

You need to buy a slot1/socket 370 adaptor. Soltek SL-02A++ adaptor is ok with this motherboard.

You can mount a pentium III processor with a 100Mhz fsb.
You can also mount a Pentium III processor with a FSB at 133Mhz but you need a software to overclock your BX chipset.
Cpucool is ok ...
ODA software CpuFsb does not with this motherboard.
Flash your bios :
You can't use intel bios file
You must use Dell bios files

Note :
I have a this model of Dell, but I replace motherboard and power supply because it's not a standart ATX power supply ( 2 connectors ...)
If you need more details don't hesitate ...
Don't buy new generation of Pentium III with a "Tualitin" core ...
