coreboot README | ||
=============== | ||
|
||
coreboot is a Free Software project aimed at replacing the proprietary BIOS | ||
(firmware) found in most computers. coreboot performs a little bit of | ||
hardware initialization and then executes additional boot logic, called a | ||
payload. | ||
|
||
With the separation of hardware initialization and later boot logic, | ||
coreboot can scale from specialized applications that run directly | ||
firmware, run operating systems in flash, load custom | ||
bootloaders, or implement firmware standards, like PC BIOS services or | ||
UEFI. This allows for systems to only include the features necessary | ||
in the target application, reducing the amount of code and flash space | ||
required. | ||
|
||
coreboot was formerly known as LinuxBIOS. | ||
|
||
|
||
Payloads | ||
-------- | ||
|
||
After the basic initialization of the hardware has been performed, any | ||
desired "payload" can be started by coreboot. | ||
|
||
See <https://www.coreboot.org/Payloads> for a list of supported payloads. | ||
|
||
|
||
Supported Hardware | ||
------------------ | ||
|
||
coreboot supports a wide range of chipsets, devices, and mainboards. | ||
|
||
For details please consult: | ||
|
||
* <https://www.coreboot.org/Supported_Motherboards> | ||
|
||
|
||
Build Requirements | ||
------------------ | ||
|
||
* make | ||
* gcc / g++ | ||
Because Linux distribution compilers tend to use lots of patches. coreboot | ||
does lots of "unusual" things in its build system, some of which break due | ||
to those patches, sometimes by gcc aborting, sometimes - and that's worse - | ||
by generating broken object code. | ||
Two options: use our toolchain (eg. make crosstools-i386) or enable the | ||
`ANY_TOOLCHAIN` Kconfig option if you're feeling lucky (no support in this | ||
case). | ||
* iasl (for targets with ACPI support) | ||
* pkg-config | ||
* libssl-dev (openssl) | ||
|
||
Optional: | ||
|
||
* doxygen (for generating/viewing documentation) | ||
* gdb (for better debugging facilities on some targets) | ||
* ncurses (for `make menuconfig` and `make nconfig`) | ||
* flex and bison (for regenerating parsers) | ||

Testing coreboot Without Modifying Your Hardware | ||
------------------------------------------------ | ||
|
||
If you want to test coreboot without any risks before you really decide | ||
to use it on your hardware, you can use the QEMU system emulator to run | ||
coreboot virtually in QEMU. | ||

# Coreboot, modified for better macbook21 support | ||
|
||
coreboot is a Free Software project aimed at replacing the proprietary BIOS | ||
(firmware) found in most computers. coreboot performs a little bit of | ||
hardware initialization and then executes additional boot logic, called a | ||
payload. | ||
This fork is for making the macbook21 support better. | ||
|
||
With the separation of hardware initialization and later boot logic, | ||
coreboot can scale from specialized applications that run directly | ||
firmware, run operating systems in flash, load custom | ||
bootloaders, or implement firmware standards, like PC BIOS services or | ||
UEFI. This allows for systems to only include the features necessary | ||
in the target application, reducing the amount of code and flash space | ||
required. | ||
For instance, a C3-State has been added in this fork and is fully functionnal | ||
|
||
coreboot was formerly known as LinuxBIOS. | ||
