Solved! Thinkpad T61p midleton bios instal

[Hristomir Hristov]

I have a thinkpad t61p laptop.
My bios version is 2.30.
I want to install Middleton Bios.
Do I need to install official version 2.29 or Middleton version 2.29 directly?

The info file of the 2.30 official BIOS says:
"If you update to the BIOS version 2.07-1.08 or later, you are not able to get
back to the older BIOS versions."
So therefore you will have to try the modified BIOS 2.29-1.08 directly, but you could get an error, that it´s prohibited to downgrade the current bios version.

You can try forcing to upgrade by editing the PHLASH.INI -> ForceUpdate=1.

Thank you very much!
I did everything as it was in the video clip.
Middleton bios installed successfully.
Do you know if I can install another version of Middleton bios later?
Because there are low voltage versions that I may need.

with the force flash method, you schould be able to downgrade the BIOS to a previous version
