NixOS profiles covering hardware quirks.
|
||||||
|
|
||||||
|
## Setup
|
||||||
|
|
||||||
|
Add and update `nixos-hardware` channel:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
|
||||||
|
$ sudo nix-channel --update nixos-hardware
|
||||||
|
```
|
||||||
|
|
||||||
|
Then import an appropriate profile path from the table below. For example, to
|
||||||
|
enable ThinkPad X220 profile, your `imports` in `/etc/nixos/configuration.nix`
|
||||||
|
should look like:
|
||||||
|
|
||||||
|
```
|
||||||
|
imports = [
|
||||||
|
<nixos-hardware/lenovo/thinkpad/x220>
|
||||||
|
./hardware-configuration.nix
|
||||||
|
];
|
||||||
|
```
|
||||||
|
|
||||||

# 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!
|
||||||
|
|
||||||
|
Documentation: https://mrchromebox.tech/#fwscript
|
||||||
|
|
||||||
|
## 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 `/`.
