You can find the source in the Chromium OS coreboot git tree and the Chromium OS u-boot git tree in the firmware-parrot-2685.B branches. This device uses coreboot and Das U-Boot to boot the system. That's to prevent a remote attacker from tricking your machine into dev-mode without your knowledge. There's no way to enter Dev-mode programmatically, and just seeing the Recovery screen isn't enough - you have to use the three-finger salute which hard-resets the machine first. If you want to leave Dev-mode programmatically, you can run crossystem disable_dev_request=1 reboot from a root shell. To leave Dev-mode and go back to normal mode, just follow the instructions at the scary boot screen. It predates the launch of that feature and it is not feasible to produce updates of devices in the field. Sorry, but this device does not support a legacy BIOS mode. Once you are in Dev-mode and have a root shell, you can run:Īnd reboot once to boot from USB drives with Ctrl-U. USB Bootīy default, USB booting is disabled. It will ask you to confirm, then reboot into dev-mode.ĭev-mode works the same as always: It will show the scary boot screen and you need to press Ctrl-D or wait 30 seconds to continue booting. To enter Dev-mode you first invoke Recovery, and at the Recovery screen press Ctrl-D (there's no prompt - you have to know to do it). To invoke Recovery mode, you hold down the ESC and Refresh (F3) keys and poke the Power button. Our partners don't really like physical switches - they cost money, take up space on the motherboard, and require holes in the case. ![]() On this device, both the recovery button and the dev-switch have been virtualized. Note: Switching between Developer and Normal (non-developer) modes will remove user accounts and their associated information from your Chromebook. If you want to browse in a safer, more secure way, leave Developer mode turned OFF. Note that Developer mode turns off some security features like verified boot and disabling the shell access. #INSTALL WINDOWS 7 ON ACER Q1VZC INSTALL#With Developer mode enabled you can do things like poke around on a command shell (as root if you want), install Chromium OS, or try other OS's. IntroductionĮnabling Developer mode is the first step to tinkering with your Chromebook. That's occasionally useful, but use it with care - it doesn't sync the disk or shut down politely, so there's a nonzero chance of trashing the contents of your stateful partition. #INSTALL WINDOWS 7 ON ACER Q1VZC SOFTWARE#Servo header: 1x50 header (now obsolete)Ĭaution: Modifications you make to the system are not supported by Google, may cause hardware, software or security issues and may void warranty.Īn unrelated note: Holding just Refresh and poking the Power button hard-resets the machine without entering Recovery.Power supply: 19V ( DC) 2.15A ( positive polarity tip).Disk: 320 GiB HD or 16 GiB SSD (might vary on specific model).RAM: 2 GiB or 4GiB DDR3 (might vary on specific model).Some later models shipped Ivy Bridge those will use the parrot_ivb board.CPU: Intel Sandy Bridge Celeron (might vary on specific model).For general information about getting started with developing on Chromium OS (the open-source version of the software on the Chrome Notebook), see the Chromium OS Developer Guide.
