Optiplex 320 "system does not support installed processor" message...

Hi everyone, my name is BillyRay and i installed the Intel Pentium 4 641 "Cedar Mill" processor and get the following message "system does not support installed processor" before system successfully boots into XP. I updated to latest Bios.This processor is H/T capable and turned on in bios.It seems to be working fine and pretty fast too.So how do i get rid of this message at start up.It dont bother me but may bother future buyers? Any ideas?

This has happened in other models, with CPU's that will work. The Dimension E510/5150 models can be upgraded to a D945 CPU.  However, as there were several different Dell motherboard part numbers used over the production of these models all the motherboards except one part number board will give the same Incompatible CPU at boot up and F1 must be pressed to continue with the bootup.  

It's an inconvenience but one that must be tolerated if a compatible upgraded CPU is used in these models.

Fortunately, its not prompting for F1 to continue at boot. I read where the Optiplex 330 and 745 did the same and Dell made a patch in a bios upgrade.Why didnt they do the same for this model? Does anyone know if you could flash the 320 with a 330 bios to fix that error message? Would be interesting to find out!
