Contents 1 Firmware as kernel 1. Firmware as kernel The normal-mode boot process is roughly this: RO firmware verifies and launches the RW firmware, RW firmware verifies and launches the kernel, the kernel verifies the rootfs as it's read from the disk. Warning This has been known to work more or less , but it's pretty annoying and difficult to debug.

Google pushes frequent updates to the running Chrome OS system so that over time it just gets better. However, since the initial portion of the BIOS is read-only, only the read-write part of the BIOS can be updated and the requirement that it interoperate with the RW portion limits the amount of change that can be applied.

In addition, updating BIOS can be a scary proposition because uncaught bugs could require users to run the recovery process. As of this writing, there are three major BIOS designs in existence, and each type loads and runs the kernel in different ways.

Our kernel has to be specially modified to handle this difference. The purpose of this tiny executable is to Update the kernel cmdline to let the kernel find the correct rootfs partition. Obtain the memory map from the BIOS that the kernel will need. Switch CPU modes from bit to bit. Jump to the kernel entry point at 0x You can replace the bootloader stub with any other UEFI application such as grub2 , but it will be broken in two ways: The BIOS' console output functions are disabled, so you can't see any output.

Coreboot initializes the bare hardware, then invokes a "payload". The payload is U-Boot, configured and customized to boot using our verified boot process without delay. Coreboot and U-Boot are both bit executables, as is the kernel entry code even for bit kernels. U-Boot updates the kernel cmdline and zeropage table, before jumping directly to 0x Any "bootstub" code is ignored.

The two nice things about the coreboot BIOS are: U-Boot can decide at boot time to enable the console output if it needs to. The handoff from BIOS to kernel is a simple bit jump. No trampoline, no reliance on run-time-resident BIOS functions. The read-write firmware is also U-Boot. You will get an odd screen saying that OS verification is off.

Keep in mind this screen will happen every single time you boot up. Press Ctrl and D to restart successfully. This will technically perform a factory data reset and wipe the laptop clean.

As you can see from the steps required to disable it, an accidental press of the spacebar at the wrong time is all you need to lose all your data once again. Chromebooks boot up extremely fast, which is a feature you will lose when Developer mode is enabled.

Their OS is now used in schools and businesses all over the world. Before getting to the installation, you have to download the latest version of Chromium for your device. You will also need a program to work with the OS image.

Here are the links to software you should download to make things work:. You can find many websites that provide Chromium for free, but we advise you to get it from Arnold the Bat. Follow the on-site instructions and download the latest version.

When the download is completed, you will have to extract the image using 7-Zip.
