[TUTORIAL] Fujitsu Esprimo LGA775 CPU Microcode Update

[tosiek]

I have tested this method on few different motherboard models.

You can run Intel Core2 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:
