[REQUEST] Toshiba Satelite Pro L450 & L455 - CPU Upgrade

[Indianatone]

I have a Toshiba Laptop model L455-S5980 which had a low performance T3000 Celeron 1.8 Ghz CPU which was castrated by Intel. I replaced it fot a T7700 2.4 GHZ Core 2 duo which the machine runs at the correct speed, the virtualization and speed step functions are enabled in the BIOS. The machine is working OK except on every boot I get the dreaded message
02F0CPU ID :FA No Microcode Update Loaded for Alternate Processor
Pressing F1 to resume boots and everything is fine.
How do I fix this? The machines are capable of running a 2.2 Pentium T4400. The machine identifies the CPU. I am using the latest bios version 1.50.
If someone gives me a tutorial I could follow it and work it out as I would be interested in what needs doing.
Thanks.

PS I tried to post a copy of the bios and nothing happened. Also it took ages for me to be able to log in.

Please replace original bios that has the same name then try to flash it.
If it can't update within windows environment,please visit this thread and try flash bios by phlash16 on dos environment.

OK followed the tutorial and used the Windows Flash and the BIOS was replaced with no issues. It works perfectly. Thank you so much.
It is important to use the tools in the tutorial and not the Toshiba tool as it will refuse to update the BIOS as the versions are the same.
Thank you so much.

Hello, hopefully someone can assist me.

I have successfully upgraded my Toshiba L450 from a T5870 to a T7800 cpu. 

It works fine but on boot up it states "No microcode update loaded for alternate processor" press F1, 
when I do this W10 boots up fine

I have updated the Bios from V1.2 to V1.5 but the problem persists 

I've attached the installed Bios v 1.5 and the CPUID screenshot.

CPU Spec Code - SLAF6

Thanks in advance!

Hello friend!!
Your t7800's stepping is g0,i have tried to inject micro code into it.
Here is download link

Please replace original bios file then try to flash it.(BIOS_V150_WIN.exe can be uncompress some file that contain flash utility and bios file,run setup.exe or setup64.exe to start updating i think. If your os is x64,please run setupx64.exe.)
If it can't correct flash,please refer to this thread to learn how to flash phoenix bios.

Try to flash my mod of BIOS.

[Hernanccs]

Hello, today i tried your file following instructions from
https://www.bios-mods.com/bios-update/

i created the DOS boot drive and downloaded phlash16 from the link the i boot the computer in DOS using the USB drive.
But when i run the command PH1614 bios.rom it starts and then gets stuck at the first step with the status on the botton saying "identifying flash memory part type"

Any suggestion?
Thanks for help

Hello

I was able to complete the BIOS update with the new microcode using the phlash16.exe that is included on
Phoenix Crisis Tool/
after the update was completed the computer shutdown itself and when i turner it back on it completed the post without any msg/error and boot Windows 10 x64 without any problem.

So i can confirm that the Intel Core 2 Duo T7700 works on this Toshiba Satellite L455-S5975

Thanks for the Help
