Does processor upgrade require bios upgrade

Metaphilos, updating the BIOS would be a good idea.  Just about every BIOS version released after version A01 had some sort of improvement related to processors.  Since Dell BIOS upgrades are cumulative, you only need to install the latest version which should be done prior installing the new processor.  You can click here for the A09 version Dell has in its File Library.   Just follow these directions for using that download.....

Once the file is downloaded to your hard drive just run the file.  The program will then prompt you into creating a bootable BIOS upgrade floppy disk so have a "good" blank one available.  Once the floppy is created just leave the floppy in the drive and reboot your system.  The BIOS upgrade program will then prompt you into updating the BIOS.  If the floppy fails to boot then check your system's boot order and make sure the floppy drive is before the hard drive in the boot sequence.  Once the BIOS upgrade is successfully done just remove the floppy disk and reboot the system.

If you encounter problems then try another download of the file and use another blank floppy disk.  If either of those two items are bad it will prevent a successful BIOS update. 

The actual time it takes the new BIOS code to be written is less than 30 seconds.  While the upgrade is in progress do not interrupt the upgrade or do the upgrade when weather conditions might indicate a possible power failure such as doing the upgrade during a thunderstorm.  An interrupted BIOS upgrade may corrupt the currently installed BIOS and thus require a motherboard replacement.

Thanks very much for the fast reply.  The advise and instructions was right-on. The upgrade

was completed like a charm. I am awaiting my processor and it installs as successfuly.

Thanks again.
