I’m still using my chromebook with coreboot as a portable thinclient. Due to small built-in storage (only 16GB), i’m also using microSD card as a secondary storage for larger files and project. However i was strugeling with microSD card not being mounted at boot (waiting for device), my solution was to just physically eject and insert the card at boot, but it is pretty inconvient and is probably destroying the card pins.

In this post i will focus on replacing the ChromeOS with Linux. Before i was running Eupnea on my chromebook, it was working alright, but the boot splashscreen was quite annoying (and recently i encourage a ‘softbrick’ after kernel update). If you want to dualboot linux+chromeos i would sugest to stick with Eupnea on external storage, like fast SD card or USB stick. What do i need? Some patience Two USB drives - one with UEFI compatible linux of your choice - I will install EndeavourOS via Ventoy because i’m too lazy to configure a decent looking arch desktop on my own, and a second one to backup stock firmware.

UPDATE 2023-08-07: Eupnea Project has been discontinued, new install of Depthboot are not recommended, if you can, just use UEFI + audio fixes. Also their Discord and Github was compromised. If you are currenty using Depthboot it is recommended to remove their repository from package manager list. Let me start with that - second-hand chromebooks are awesome value for cheap, long-lasting battery, portable Netflix and SSH machine. I’ve got my Chromebook about a year ago for 55 USD, it is a HP Chromebook 11a G6.
