Bios Mods -The Best BIOS Update and Modification Source

I have an OptiPlex 380 with a Phoenix bios that has SLIC 2.1, So no problem with win7. I need to get an OptiPlex without SLIC 2.1 updated. Is there a way to make use of the SLIC 2.1 bios to update the other? If not here is the info needed to do a mod.

Manufacturer: Dell OptiPlex 380
-Motherboard Model:R64DJ
-Bios revision:A07
-Bios Type: Phoenix BIOS
-Bios Download Link: ROM file attached as zip

Thanks in advance for any help you can give.[attachment=6389][attachment=6390]
