    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:

    menuentry 'Load Operating System (incl. fully encrypted disks)  [o]' --hotkey='o' {
    
            if [ "${grub_scan_disk}" != "ata" ]; then
    
    		search_grub ahci
    
    	fi
    
    	if [ "${grub_scan_disk}" != "ahci" ]; then
    
    		search_grub ata
    
    	fi
    
            # grub device enumeration is very slow, so checks are hardcoded
    
            # TODO: add more strings, based on what distros set up when
    
    	# the user select auto-partitioning on those installers
    
    	lvmvol="lvm/matrix-bootvol lvm/matrix-rootvol"
    
            raidvol="md/0 md/1 md/2 md/3 md/4 md/5 md/6 md/7 md/8 md/9"
    
            # in practise, doing multiple redundant checks is perfectly fast and
    
    	# TODO: optimize grub itself, and use */? here for everything
    
            for vol in ${lvmvol} ${raidvol} ; do
    
    		try_user_config "${vol}"
    
    	done
    
            unset ahcidev
    
    	unset atadev
    
    	for i in 11 10 9 8 7 6 5 4 3 2 1 0; do
    
    		for part in 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1; do
    
    			if [ "${grub_scan_disk}" != "ata" ]; then
    
    				ahcidev="(ahci${i},${part}) ${ahcidev}"
    
    			fi
    
    			if [ "${grub_scan_disk}" != "ahci" ]; then
    
    				atadev="(ata${i},${part}) ${atadev}"
    
    			fi
    
    		done
    
    	done
    
            set pager=0
    
    	echo -n "Attempting to unlock encrypted volumes"
    
    	for dev in ${ahcidev} ${atadev} ${lvmvol} ${raidvol}; do

    	set pager=1

            # after cryptomount, lvm volumes might be available
    
    	for vol in ${lvmvol}; do
    
    		try_user_config "${vol}"
    
    	done
    
            search_grub crypto
    
            if [ "${grub_scan_disk}" != "ata" ]; then
    
    		# Last resort, if all else fails
    
    		set root=ahci0,1
    
    		for p in / /boot/; do
    
    			if [ -f "${p}vmlinuz" ]; then
    
    				linux ${p}vmlinuz root=/dev/sda1 rw
    
    				if [ -f "${p}initrd.img" ]; then

    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:

    1. Boot with kernel parameter iomem=relaxed
    2. 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
    
    1. 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?


  • You wrote the correct command $ ./build roms t440plibremrc_12mb , but I want to understand how I can check the ROM before flashing the firmware, is everything okay, are the blobs embedded so that I can boot my laptop, this was the command before:

    ./cbfstool grub_t440pmrc_12mb_libgfxinit_corebootfb_usqwerty.rom print

    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
