How to install OpenBSD on a libreboot system

+ This section relates to preparing, booting and installing a + OpenBSD distribution on your libreboot system, using nothing more than a USB flash drive (and dd). They've only been tested on a Lenovo ThinkPad x200. +

+ +

+ This section is only for the GRUB payload. For depthcharge (used on CrOS devices in libreboot), instructions + have yet to be written in the libreboot documentation. +

+ +

Prepare the USB drive (in OpenBSD)

+ +

+ Connect the USB drive. Check dmesg:
+ $ dmesg | tail
+ + Check to confirm which drive it is, for example, if you think its sd3:
+ $ disklabel sd3 +

+ +

+ Check that it wasn't automatically mounted. If it was, unmount it. For example:
+ $ doas umount /dev/sd3i
+

+ +

+ dmesg told you what device it is. Overwrite the drive, writing the OpenBSD installer to it with dd. For example:
+ $ doas dd if=install60.fs of=/dev/rsdXc bs=1M; sync
+

+ +

+ You should now be able to boot the installer from your USB drive. Continue reading, for + information about how to do that. +

+ +

+ +

Installing OpenBSD without full disk encryption

+ +

+ Press C in GRUB to access the command line: +

+ grub> kopenbsd (usb0,openbsd1)/6.0/amd64/bsd.rd +

+ It will start booting into the OpenBSD installer. Follow the normal process for installing OpenBSD. +

+ +

+ Back to top of page. +

+ +

Installing OpenBSD with full disk encryption

+ +

+ Not working. You can modify the above procedure (installation w/o encryption) to install OpenBSD using full disk encryption, and it appears to work, except that its not yet clear how to actually boot an OpenBSD+FDE installation using libreboot+Grub2. If you get it working, please let us know. +

+ +

+ +

Booting

+ +

+ Press C in GRUB to access the command line: +

+ grub> kopenbsd -r sd0a (ahci0,openbsd1)/bsd +

+ OpenBSD will start booting. Yay! +

+ +

+ Back to top of page. +

+ +

Configuring Grub

+ +

+ If you don't want to drop to the GRUB command line and type in a command to boot OpenBSD every time, you can create a GRUB configuration that's aware of your OpenBSD installation and that will automatically be used by libreboot. +

+ On your OpenBSD root partition, create the /grub directory and add the file libreboot_grub.cfg to it. Inside the libreboot_grub.cfg add these lines: +

+ default=0 + timeout=3 + menuentry "OpenBSD" {
+ kopenbsd -r sd0a (ahci0,openbsd1)/bsd
+ }
+

The next time you boot, you'll see the old Grub menu for a few seconds, then you'll see the a new menu with only OpenBSD on the list. After 3 seconds OpenBSD will boot, or you can hit enter to boot. +

+ Back to top of page. +

+ +

Troubleshooting

+ +

+ 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 OpenBSD distributions + it can be problematic when they are trying to switch to a framebuffer because it doesn't exist. +

+ +

+ In most cases, you should use the vesafb ROM images. Example filename: libreboot_ukdvorak_vesafb.rom. +

+ +

won't boot...something about file not found

+ You device names (i.e. usb0, usb1, sd0, sd1, wd0, ahci0, hd0, etc) and numbers may differ. Use TAB completion. +
