Utente Super Principiante Prova a Installare GNU BOOT: Varie domande.

Hello everyone, I am a new user.

I am not very knowledgeable about computers and electronics but I can follow the guides if they are clear. I joined because I am trying to install GNU BOOT on a T60 and I have several questions. There are many guides on the web but they all dictate slightly different commands and I don't know which ones are the most appropriate to install GNU BOOT in the safest/complete/effective way possible.

(1) First you need to update the bios and this I have done.

(2) As second thing one would need to install trisquel on the pc (no problem).

(3) As the third thing one would need to backup the bios with flashrom. I installed flashrom but I didn't understand what commands should be given....

(4) As fourth step you would need to install gnu boot rom using flashrom, here the guides give different directions and I don't know what commands to give.

(5) Which of the 5 RC versions is the most secure and stable? Is the corebootfb or txtmode version better?

(6) Of course, I also haven't figured out how to go back to the original bios in case I change my mind....

Does anyone have the patience to help me?
