I'm not sure what you mean by "checking the ROM"...
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I’m not sure what you mean by “checking the ROM”…
Hello . I mean, how do I know that there are blob objects embedded in the ROM, without which my laptop won’t turn on, I mean mrc.bin
Previously I could check this using the command:
./cbfstool grub_t440pmrc_12mb_libgfxinit_corebootfb_usqwerty.rom print
Oh you can still do that. The path changed to elf/cbfstool/[TREE]/cbfstool
(replace [TREE]
with the tree concerened). Note that since the switch to the libre RAM init code, mrc.bin
is not included anymore
I installed the updated version 20240612 everything worked as you said. Checking nothing as in the previous instructions does not give anything, as you wrote: after switching to the libre RAM initialization code mrc.bin no longer turns on
.
Now i need to edit grub.cfg
because I get an error with searching for the achi1 disk
$ ./build roms t440plibremrc_12mb
Thanks for your answer and help. I understand you correctly that after I executed the command
$ ./build roms t440plibremrc_12mb
Then I can update my ROM (for example, I now have 2023.06.25) by running the commands:
- Boot with kernel parameter
iomem=relaxed
- Download and install ** flashprog** since flashrom will not work (for me it shows the chip size as 8Mb instead of 12Mb)
$ git clone https://github.com/SourceArcade/flashprog.git
$ cd flashprog
$ make
$ sudo make install
- Check for errors with the command:
$ sudo flashprog -p internal
4 Flash
$ sudo flashprog -p internal -w seabios_withgrub_t440plibremrc_12mb_libgfxinit_corebootfb_ukqwerty_grubfirst.rom
And can I be sure that after turning on my computer I will see Grub Libreboot?
Yeah, that's basically right. I believe flashprog is also included in libreboot, have a look in the elf/
directory. After that, it should work as expected

Thank you, kind person)) I installed it, but after installation my screen is too bright
and this happens every time, so for now I will use the latest test version, it works well.
I have another question, please tell me how, in your opinion, I can edit grub.cgf correctly so as not to get an error with searching for disk "ahci1"
I inserted these lines:
...........
echo # Insert newline
}
menuentry 'Load GNU/Linux-Libre (LTS)' {
cryptomount -a
set root='lvm/matrix-rootvol'
linux /boot/vmlinuz-linux-libre-lts root=/dev/mapper/matrix-rootvol cryptdevice=/dev/sda1:lvm
initrd /boot/initramfs-linux-libre-lts.img
}
menuentry 'Load Operating System (incl. fully encrypted disks) [o]' --hotkey='o' {
and deleted these ones since I don't use raid
:

Hmm, I'm not sure... I must admit, I only use SeaBIOS, not GRUB, so I wouldn't know how to configure it
How to install Libreboot in 2024?
That’s an oddly specific question. When else but now? Did you arrive by time machine?

Yes, I was looking for you and I want to take you to my planet called GnuBoot, will you come with me? ))
ok, thanks
