Bios Settings for P3 600mhz Optiplex 450L+

I would like to upgrade the Slim Optiplex GX1 450L+ P3 450mhz CPU to a P3 600mhz CPU.  Does anyone know what are the correct Bios settings to do this .. ie correct bios version, settings on the motherboard? Do I have to be concerned about the extra heat/voltage given off by the CPU and static electricity? What are the correct procedures to do remove the 450mhz and replace with the 600mhz?  I am running XP and my present bios is A07. Thanks.

Is it a 600/512 or 600/256 processor?

The 600/512 (Katmai core) should work with a bios up to A10, but the coppermine and tualatin processors require bios A07.

Stick with A07 for safety; there have been many cases of 600MHz processors not running above that - the detection is done by a timing loop in the bios not by working out the processor type.  You can go to 1GHz slot 1 PIIIs or 1.1 GHz Celeron socket 370 coppermines using a super slocket III adaptor if you haven't already got the processor - you're not limited to 600MHz...

Thank you. 
 
 Is there anything I have to change physically on the motherboard i.e. jumper settings, etc

set the speed jumper to 266mhz or remove the speed jumper.
