Dear Philip, First of all, please respect the netiquette and do not top post. It makes replying much harder. Please use the interleaved style in the future.

Second, I really think this not a SeaBIOS issue, but a hard drive issue. But it seems functional, as SeaBIOS is listing it in the boot menu, and you can access it from the live installation. > I managed to get some feedback from Kevin, on IRC, which was set debug to > 8... > I began the adventure, by taking advantage of a pureos script > https://code.puri.sm/kakaroto/coreboot-files/raw/master/build_coreboot.sh > > I had to make a few modifications > megadl ' > https://mega.nz/#!fA03xADA!5uqZiKwNZIP1J27xHzIKVQPQaNfqxdtzKjPRxxwZMc8' > mv Intel\ CSME\ 11.0\ Firmware\ Repository\ Pack\ r50.rar > coreboot/me_11_repository.rar > comment out lines 226 and 227 > cd coreboot/flashrom && CFLAGS="-Wno-error=deprecated-declarations" > make; cd - > update the librem15v3 coreboot config file, setting seabios debug from > -1 to 8 > comment out the attempt to check the sha256 of the coreboot (since > debug changes sha) > the script created a coreboot rom file and claimed that it flashed the > rom > > However, when I rebooted, I didn't see any extra output on the screen and > it is still hung on the Booting from Hard disk... message > > Any thoughts on how I can get the debug output? 1. You need to capture the coreboot and SeaBIOS messages. Does the device have ports which can be used for debugging? As it’s a laptop, that is probably not the case. You could see if the messages are preserved during reboot. So, plug in the device with the live distribution, try to boot from the drive, get the error, and (warm) reboot, and select the distribution. Build `cbmem`, by getting the coreboot source code [1], and then do `make -C util/cbmem`. Or start a Linux kernel with `CONFIG_GOOGLE_MEMCONSOLE_COREBOOT` and look into `/sys/firmware/log`. 2. See if the option *SPI Flash console output* (`CONFIG_CONSOLE_SPI_FLASH`) is supported on your board. The Puri.sm folks should know and help you with that. > Send coreboot debug output to the SPI Flash in the FMAP CONSOLE area > > This option can cause premature wear on the SPI flash and should not > be used as a normal means of debugging.

Hello biosers, I managed to get some feedback from Kevin, on IRC, which was set debug to 8... I began the adventure, by taking advantage of a pureos script https://code.puri.sm/kakaroto/coreboot-files/raw/master/build_coreboot.sh I had to make a few modifications megadl ' https://mega.nz/#!fA03xADA!5uqZiKwNZIP1J27xHzIKVQPQaNfqxdtzKjPRxxwZMc8' mv Intel\ CSME\ 11.0\ Firmware\ Repository\ Pack\ r50.rar coreboot/me_11_repository.rar comment out lines 226 and 227 cd coreboot/flashrom && CFLAGS="-Wno-error=deprecated-declarations" make; cd - update the librem15v3 coreboot config file, setting seabios debug from -1 to 8 comment out the attempt to check the sha256 of the coreboot (since debug changes sha) the script created a coreboot rom file and claimed that it flashed the rom However, when I rebooted, I didn't see any extra output on the screen and it is still hung on the Booting from Hard disk... message Any thoughts on how I can get the debug output?

Librem 15v3 hangs at Booting from Hard Disk...

Hello everyone! I've been having some issues with a laptop recently. My Librem 15v3 was bouncing along, until one day I ran into an apt-get upgrade issue. I attempted to fix the affected script by pointing it to the base directory busybox lived. The upgrade completed without any apparent issue. But, now no matter what I do, unattended boots hang on SeaBIOS (version rel-1.11.0-0-g63451fc) Booting from Hard Disk... _ I have tried reinstalling the OS, using their live boot ISO. Each time, no matter which disk I configure (/dev/sda or /dev/nvme0n1), the install fails with the message Installation failed Failed to run update-initramfs on the target The exit code was 2 I have upgraded coreboot, no joy. I have also tried manually running grub, from the installer, ie 1. mkdir /mnt/root 2. cryptsetup luksOpen /dev/sda3 root 3. mount /dev/mapper/root /mnt/root 4. mount /dev/sda1 /mnt/root/boot 5. grub-install --boot-directory=/mnt/root/boot /dev/sda 6. update-grub2 The folks at purism/librem seem to be as confused as I am. Does anyone here have any insight into how I can fix this problem? Thanks!
