Upgraded T7500 CPU on a Toshiba L500

Hi guys, I succesfully upgraded a T7500 on my Toshiba L500. It works perfectly but, after the bios screen, it shows me the list of the installed hardware and at the end "FB No microcode update loaded for alternate processor"; I have to press F1 and Windows 8.1 starts properly. I hope you can help me.

- I've attached the installed Bios v 2.1 and the CPUID screenshot.
- CPU spec code: SLAF8
