BIOS upgrade for Dell Dimension XPS T500

February 12, 2011 at 17:08:08
Specs: Windows 2000, P3 575MB

I have previously seen on the Dell website an upgrade BIOS from Version 5 to Version 9 but can't find any mention on the current Dell website. Any ideas where I can download a new BIOS. The computer is working fine except for occasional lockups but a BIOS upgrade may help.

A bios update and a bios upgrade are two different things.
See the last part of response 28:

Dell does not have bios upgrades.

"The computer is working fine except for occasional lockups but a BIOS upgrade may help."

Then you DO NOT update the bios !
Flashing the bios is NOT a fix-all !
It's the riskiest thing you can do with a computer !

Agreed. If you machine is locking up, it's highly unlikely that it's due to the BIOS. As Tubesandwires mentions, you can turn your PC into a doorstop rather quickly. You need to investigate further into the cause of the lockups...

Hi again

Thanks for all your advice which of course is perfectly correct i.e. don't do it unless you have to. I once turned a DVD player into the aforementioned doorstop by attempting to upgrade the firmware. I have since found all the BIOS versions and more and so I can compare them. They are all listed as optional so there is probably nothing to be gained by flashing to a later one.
Mickliq has found a link to take you direct to Dell and I thank him for that. Searching for "BIOS for Dell Dimension XPS T500" failed to find what I was looking for but a search for "Dell Dimension XPS T500" did and then drilling down through the information got me to where I wanted to be. "Be Careful How You Use a Search Engine" seems to be the lesson. Thanks for all your advice, sometimes you just need another opinion or a push in the right direction.

I now consider this topic to be closed but I will look in from time to time to see if there are any other comments I should be aware of.

Thanks again

It makes absolutely no sense at all to flash your bios if your computer worked fine AT ANY TIME with the same bios version and cpu previously.

If the release notes for the bios versions that are newer than the mboard presently has do not mention a problem that is fixed by flashing the bios that is definitely your case, it's extremely unlikely flashing the bios is going to solve your problem(s).

Generally, brand name bios updates have very little if anything for release notes, in comparison to what retail desktop mboards generally have for their bios updates.

Usually a newer bios update includes all the previous fixes, unless there was a problem with something that was changed.

In most cases, the only legitimate reason for flashing the bios is if you want to install a cpu in the future that the mboard supports for sure that present bios version does not support recognizing, and the confirmed info about that is not likely to be found for brand name systems, unless that's mentioned in release notes.

Retail desktop mboard models generally have a CPU support list on the manufacturer's web site with the minimum bios version required stated on the same line as each cpu. There are even some web sites where you can look up the cpus for many mboard manufacturers retail models in one place that often show the minimum bios version required too - e.g.
If a brand name system has a retail or OEM mboard model that is on the mboard manufacturer's web site, that of course has a brand name system bios version, there's no certainty that the brand name system bios versions support the same cpus as the mboard manufacturer's versions

When it's a Dell computer...
Go here for how to find the Service tag "number":

Then you use that Service tag number to find the exact support for your model and configuration (e.g. the cards that may come with a desktop system vary), or as close as you can to that, on the Dell web site.
