Dell Optiplex and Latitude BIOS
Keep your BIOS (basic input output system) current. Most people know to keep their operating system and programs up to date. Yet, most users overlook keeping the BIOS current.
What is BIOS?
BIOS is the software that runs the computer without using the operating systems or other programs.
What is my BIOS version?
When you start your computer, one of the first screens to appear is the BIOS screen. The BIOS version will be displayed on this page. Go to you computer manufacturer’s web site and find if your version is the most current. Most manufacture web sites have downloadable BIOS files with instructions for updating your BIOS.
Here is a list of Dell computers that I work with and their current BIOS version.

Is it possible to roll back to a previous Bios Version. I just upgraded to a PowerLeap Hyper Threading CPU and the latest Optiplex GX260 Bios Rev A09 will not recognize the HT technology in the chip.

Gary,
You can not “roll back” a BIOS update.
However, you can re-install any previous BIOS version. If you do not have the earlier BIOS disk/file, you can download the file at http://support.us.dell.com/support/downloads/format.aspx?releaseid=R86304 and create a new BIOS boot disk or download the executable file.
