How to install GnuBoot?
- Anmelden oder Registrieren um Kommentare zu schreiben
Hello everyone. I wanted to create an important topic here so that we can share our experience of installing GnuBoot on our computers, help each other.
Waiting for my T400 package to start installing Gnuboot.
Useful links information on Gnuboot:
gnuboot-0.1-rc3 => https://ftp.gnu.org/gnu/gnuboot/gnuboot-0.1-rc3/roms/
https://savannah.gnu.org/projects/gnuboot
irc channel #gnuboot
I am a translator!
I suggest using https://www.gnu.org/software/gnuboot/web/docs/install/install.html as start page.
All necessary pieces of information are there but not at all in order, which can be confusing.
If I had to list steps, it would be:
1. Check your flash size (flashrom -p internal)
2. Decide which payload you want (SeaBIOS is like legacy BIOS, well documented in all distros, so easiest to use)
3. Download the rom for your flash size, the selected payload and your keyboard layout
4. Get the source and build ich9utils (this is for T400, X200 and similar)
5. Use ich9gen to set the MAC address to your current MAC address
For internal flashing (if you have an old Libreboot):
6. Reboot with iomem=relaxed as kernel parameter (by editing the start command in GRUB menu)
7. Save your current ROM
8. Flash
9. If it says success, ask to switch off, then boot
One difficulty I had was to get the GPG key that was used to sign the things to download. Maybe I got it from pgp.mit.edu, but I cannot remember well.
Hello Avron .
Thank you very much for your instructions and feedback.
I wanted to clarify with you about step 4, do I understand correctly that the ich9utils utility is needed to change the mac address?

Do I understand correctly that the ich9utils utility is needed to change the mac address?
Yes. As explained in https://www.gnu.org/software/gnuboot/web/docs/install/ich9utils.html, you need to run "ich9gen –macaddress 00:1f:16:80:80:80" (replace 00:1f:16:80:80:80 with your actual ethernet controller MAC address) to generate a flash descriptor with your MAC address and then run a dd command to add what was generated to the rom you want to flash.
I am not sure whether the roms ready to download have no descriptor/address at all (and then, if you flash them without doing these steps, ethernet will not work) or have one with a fixed address (then ethernet may work but you may have some problems).

Thank you for your answer. I couldn’t figure out where to download this program on the site https://www.gnu.org/software/gnuboot/web/docs/install/ich9utils.html, I found this solution:
$ git clone https://notabug.org/libreboot/ich9utils
$ cd ich9utils
$ make

And the program is ready to work)

I got it from https://ftp.gnu.org/gnu/gnuboot/gnuboot-0.1-rc3/gnuboot-0.1-rc3_src.tar.xz (the source package).
Avron, thank you very much for the link, I downloaded the archive and found the program there.
Avron, if you don’t mind, I would like to describe in a little more detail the installation process that you wrote, so that the instructions are saved here for other users who want to install GnuBoot and look for answers through a search engine.
I'll try to write later with commands and photos...
