Google "Slippy" Chromebook Supported By Coreboot
Phoronix: Google "Slippy" Chromebook Supported By Coreboot
As of Saturday night the "Slippy" is the latest Google Chromebook to be supported by the open-source Coreboot firmware. As with supporting other Chromebooks, adding support for the codenamed Haswell mobile device added a great deal of new code...
The whining here is just amazing...
Well, Dev-Mode is ChromeOS Dev-Mode - if you want more than that (and avoid the 30 seconds wait time in particular), you'll have to open the box and tweak a screw (which serves as a jumper). Once.
Those 30 seconds (with scary splash screen) are part of the security model, the idea being that to open the box you'll need long enough, doing suspicious activity that you can't take over any ChromeOS device that's unsupervised for 5 minutes, while Dev Mode is the easy way for "light" modifications.
There are plenty of boards that don't allow you to override the flashing procedure at all, except by directly attaching to the chip with expensive equipment. Google makes it feasible with their boxes, documents it (eg. Acer C720: http://www.chromium.org/chromium-os/...720-chromebook see "write-protect screw") and you choose to - whine? Absolutely amazing.
http://johnlewis.ie/pre-built-corebo...r-chromebooks/ describes the process in great detail. It's possible to get rid of the 5 seconds delay he encountered, but I don't have his models around to fix things - but that's not "evil Google", it's a bug.
With some more effort, you can even get Windows to run natively on those boxes (I did).
tl;dr: On a chromebook there's regular ChromeOS mode, Dev Mode and tinkerer mode (opening the box required once). Somehow people forget about the last one.
