[TUTORIAL] Fujitsu Esprimo LGA775 CPU Microcode Update

[tosiek]

I have tested this method on few different motherboard models.

You can run Intel® Core™2 Duo Processor E8400 on Fujitsu d2840 A1 motherboard for example.

1. You have to just find another similar motherboard which support your new CPU. I choose D2950.
   
2. Download bios for both motherboards from: http://support.ts.fujitsu.com/IndexDownload.asp
   
3. Copy two files from newer MB: P6_INTEL.ALL and P6_INTEL.TXT and replace in your correct bios.
   
4. Flash the bios with switch /p6
   bioflash.exe /p6

Other switches for bioflash:
