Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

Check dmesg:<br/> - <b>$ dmesg</b><br/> - - Check lsblk to confirm which drive it is:<br/> - <b>$ lsblk</b> - </p> - - <p> - Check that it wasn't automatically mounted. If it was, unmount it. For example:<br/> - <b>$ sudo umount /dev/sdb*</b><br/> - <b># umount /dev/sdb*</b> - </p> - - <p> - dmesg told you what device it is. Overwrite the drive, writing your distro ISO to it with dd. For example:<br/> - <b>$ sudo dd if=gnulinux.iso of=/dev/sdb bs=8M; sync</b><br/> - <b># dd if=gnulinux.iso of=/dev/sdb bs=8M; sync</b> - </p> - - <h2>Booting the USB drive (in GRUB)</h2> - - <p> - Boot it in GRUB using the <i>Parse ISOLINUX config (USB)</i> option (it's in default libreboot grub.cfg, at least). - - A new menu should appear in GRUB, showing the boot options for that distro; this is a GRUB menu, converted from the usual - ISOLINUX menu provided by that distro. - </p> - - <p> - If the ISOLINUX parser won't work, then press C to get to GRUB command line.<br/> - grub> <b>ls</b><br/> - - Get the device from above output, eg (usb0). Example:<br/> - grub> <b>cat (usb0)/isolinux/isolinux.cfg</b><br/> - - Either this will show the ISOLINUX menuentries for that ISO, or link to other .cfg files, for example /isolinux/foo.cfg.<br/> - - If it did that, then you do:<br/> - grub> <b>cat (usb0)/isolinux/foo.cfg</b><br/> - - And so on, until you find the correct menuentries for ISOLINUX. - </p> - - <p> - Now look at the ISOLINUX menuentry. It'll look like:<br/> - <b> - kernel /path/to/kernel<br/> - append PARAMETERS initrd=/path/to/initrd MAYBE_MORE_PARAMETERS<br/> - </b> - - GRUB works the same way, but in it's own way. Example GRUB commands:<br/> - grub> <b>linux (usb0)/path/to/kernel PARAMETERS MAYBE_MORE_PARAMETERS</b><br/> - grub> <b>initrd (usb0)/path/to/initrd</b><br/> - grub> <b>boot</b><br/> - - Of course this will vary from distro to distro. If you did all that correctly, it should now be booting the ISO - the way you specified. - </p> - - <h1>Troubleshooting</h1> - - <p> - Most of these issues occur when using libreboot with coreboot's 'text mode' instead of the coreboot framebuffer. - This mode is useful for booting payloads like memtest86+ which expect text-mode, but for GNU/Linux distributions - it can be problematic when they are trying to switch to a framebuffer because it doesn't exist. - </p> - - <p> - In most cases, you should use the vesafb ROM's. Example filename: libreboot_ukdvorak_vesafb.rom. - </p> - - <h2>parabola won't boot in text-mode</h2> - - <p> - Use one of the ROM images with vesafb in the filename (uses coreboot framebuffer instead of text-mode). - </p> - - <h2>debian-installer (trisquel net install) graphical corruption in text-mode</h2> - <p> - When using the ROM images that use coreboot's "text mode" instead of the coreboot framebuffer, - booting the Trisquel net installer results in graphical corruption because it is trying to switch to a framebuffer which doesn't - exist. Use that kernel parameter on the 'linux' line when booting it:<br/> - <b>vga=normal fb=false</b> - </p> - - <p> - Tested in Trisquel 6 (and 7). This forces debian-installer to start in text-mode, instead of trying to switch to a framebuffer. - </p> - - <p> - If selecting text-mode from a GRUB menu created using the ISOLINUX parser, you can press E on the menu entry to add this. - Or, if you are booting manually (from GRUB terminal) then just add the parameters. - </p> - - <p> - This workaround was found on the page: <a href="https://www.debian.org/releases/stable/i386/ch05s04.html">https://www.debian.org/releases/stable/i386/ch05s04.html</a>. - It should also work for gNewSense, Debian and any other apt-get distro that provides debian-installer (text mode) net install method. - </p> - -<hr/> - - <p> - Copyright © 2014 Francis Rowe <info@gluglug.org.uk><br/> - This document is released under the Creative Commons Attribution-ShareAlike 4.0 International Public License and all future versions. - A copy of the license can be found at <a href="../license.txt">../license.txt</a>. - </p> - - <p> - This document is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
