provide a fast, simple, and more secure computing experience for users who spend most of their time online.
Key Benets
• Speed
• Simplicity
• Security
• Updatability
• Syncronisability
• High power at low cost
• Easy to learn and use
Software 15
Page 16
• Documents, calendar, e-mail, contacts, and tasks available online and oine, and all securely backed-up and synchronised in the cloud.
• Access to the Chrome web app store
• Killer web apps
• The latest Intel Core processors
• Fun games
• Built-in support for popular le types and external devices
For more information about the Chrome OS, please visit the Chrome OS training page.
Veried Boot
Read Only rmware veries the integrity of Read/Write (R/W) rmware. R/W rmware veries the active Linux kernel. During run time,
the kernel veries each block read from disk.
If a verication step fails and there is no backup option, the machine enters recovery mode.
The Developer Mode switch turns o veried boot (at the Kernel stage) to enable users to run Chromium OS (or other OS). The BIOS is
always veried.
Software
16
Page 17
Disk Partition Map
There are two copies of Chrome OS on disk: an active copy and a backup copy. Each copy consists of a kernel partition and a root le
system. The backup copy is updated automatically in the background. Users only need to reboot. The partition contains encrypted user
data and is also used in the factory for storing test software.
Software

Developer and Recovery mode
Table 20. Developer and Recovery mode
Developer Mode Recovery Mode
• Used to boot without verication.
• Can be turned on via key combination during boot.
• Stateful partition is wiped during transitions.
• Used in the factory to boot test image.
• Allows a user to reinstall the Chrome OS from a USB key or SD
card.
• Recovery mode is entered if veried boot fails.
• A user can force recovery mode via a key combination during
boot.
Coreboot and U-boot Custom Firmware
Coreboot (x86 only)
• Memory and chipset initialization
• Open-source, except for MRC binary from Intel.
U-Boot
• Performs veried boot
• Handles recovery and Developer Mode
• Open source code
Normal boot is very fast, as it takes less than 1 second to start loading kernel. Chromebook does not boot other operating systems such as
Windows or OS X.
