Not sure if it's EFI as well, but Chrome OS implements this as "verified boot"[1]. If the OS doesn't check out, it falls back on a backup copy on the SSD (and if that one's bad too, it asks for a recovery SD card). Google mandates a "devmode" switch to bypass it, enabling it wipes all data and adds a warning screen at boot (to avoid malicious rooting), but you have full control after hitting the switch.

- sp332 15y agoYeah, it's EFI. But you can't boot Linux on it because the EFI is "stripped down" and is missing some functions that Linux needs to boot.
- trobertson 15y agoThat's not entirely true, at least on the cr-48. Here is the install guide to get ubuntu on a cr-48[1]. The docs do say, however, that the cr-48 lacks initrd, so you have to modify the ubuntu kernel to get it to boot.

- sp332 15y agoInteresting, that seems like a lot of work :) I've seen a simpler hack that rewrites the EFI firmware to emulate a normal BIOS and then installs vanilla Ubuntu or even Windows on it. http://corey.degrandchamp.com/2011/04/10/flash-google-cr-48-bios-without-luigi-or-ubuntu/ http://corey.degrandchamp.com/2011/04/10/flash-google-cr-48-...
- ConstantineXVI 15y agoI'd like to point out that your counter to doing "a lot of work" involves totally disassembling the Cr-48.
- sp332 15y agoWell, you just have to take the bottom off but it is a lot of screws. Still, I bet it's faster and less hassle.
