5 coreboot is a Free Software project aimed at replacing the proprietary BIOS
6 (firmware) found in most computers. coreboot performs a little bit of
7 hardware initialization and then executes additional boot logic, called a
10 With the separation of hardware initialization and later boot logic,
11 coreboot can scale from specialized applications that run directly
12 firmware, run operating systems in flash, load custom
13 bootloaders, or implement firmware standards, like PC BIOS services or
14 UEFI. This allows for systems to only include the features necessary
15 in the target application, reducing the amount of code and flash space
18 coreboot was formerly known as LinuxBIOS.
24 After the basic initialization of the hardware has been performed, any
25 desired "payload" can be started by coreboot.
27 See https://www.coreboot.org/Payloads for a list of supported payloads.
33 coreboot supports a wide range of chipsets, devices, and mainboards.

46 Because Linux distribution compilers tend to use lots of patches. coreboot
47 does lots of "unusual" things in its build system, some of which break due
48 to those patches, sometimes by gcc aborting, sometimes - and that's worse -
49 by generating broken object code.
50 Two options: use our toolchain (eg. make crosstools-i386) or enable the
51 ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this
53 * iasl (for targets with ACPI support)
55 * libssl-dev (openssl)
59 * doxygen (for generating/viewing documentation)
60 * gdb (for better debugging facilities on some targets)
61 * ncurses (for 'make menuconfig' and 'make nconfig')
62 * flex and bison (for regenerating parsers)

71 Testing coreboot Without Modifying Your Hardware
72 ------------------------------------------------
74 If you want to test coreboot without any risks before you really decide
75 to use it on your hardware, you can use the QEMU system emulator to run
76 coreboot virtually in QEMU.
78 Please see https://www.coreboot.org/QEMU for details.
