+# Toshiba Chromebook 2 `swanky`
+
+There might be a way to install NixOS without hardware modifications (via
+enabled developer mode and SeaBIOS boot on Ctrl+L), however I'd highly
+recommend replacing Google's Coreboot payload with Tianocore: that allows for
+proper virtualization, suspend, removes annoying developer mode screen, and
+generally just works much better.
+
+These instructions carry some risk of bricking your device, since you'll be
+reflashing BIOS. Risk is rather low, but please for the love of god make a BIOS
+backup and store it someplace safe. That's the only way to reinstall ChromeOS
+back after this procedure (BIOS image has licensing info), and it's much easier
+to use a known good state to unbrick the laptop if things go wrong.
+
+If you ever get unlucky, you can unbrick your device using Raspberry Pi,
+some cables and a SOIC clip, see:
+http://sicarul.com/how-to-un-brick-your-toshiba-chromebook-2-gandof-without-invoking-any-demons/
+
+## Enable developer mode
+
+This will wipe all user data and settings from the laptop.
+
+Power off, then hold ESC + Refresh (F3) and abruptly press power button. You
+should see "Chrome OS is missing or damaged" message. Press Ctrl+D. Press enter
+at the next screen, then press Ctrl+D again. Wait until the laptop boots into
+ChromeOS, then power it off.
+
+## Disable hardware-backed BIOS write protection
+
+Follow the first part of the guide at:
+https://github.com/brendenyule/NativeToshibaCB2Guide/wiki/Remove-Write-Protect
+
+Ignore SeaBIOS section. I also used some ductape over #5 to make sure that
+metallic motherboard shield would not re-enable write protection.
+
+## Flash Coreboot + Tianocore BIOS
+
+Prepare a FAT32-formatted flash drive for BIOS backup in advance.
+
+Go through ChromeOS installation dialogues until you have network access and
+are able to log into a guest session. Open Chrome, press Ctrl+Alt+T to open
+`crosh`, type in `shell` to get a real shell. Then, run:
+
+```
+$ cd ~
+$ curl -LO https://mrchromebox.tech/firmware-util.sh
+$ sudo bash firmware-util.sh
+```
+
+Choose "Install/Update Full ROM Firmware" option and follow instructions.
+Do not skip BIOS backup!

+
+## Enable hardware-backed BIOS write protection
+
+This is a cool security feature, so after flashing Coreboot + Tianocore BIOS
+and making sure new BIOS works, consider re-enabling BIOS protection. Just put
+in the missing screw #5.
+
+## Install NixOS
+
+`dd` an image on a flash drive, partition the drive, etc. On some later models,
+you can swap SSD with any other 2242 M.2 SATA SSD, but on `swanky`, you have
+to live with what you have (16GB eMMC). I recommend `256MB` for EFI partition,
+and the rest for `/`.
