Keith Hui b48ba6625b From Keith Hui: This patch implements a full SDRAM buffer strength programming algorithm in set_dram_buffer_strength(), checked against my P2B-LS factory BIOS. With this in place, I now have 133MHz (!) stability with three 256MB PC133 modules, and can boot Fedora 11 all the way to the init daemon (actually upstart, but that's another story). Not to login prompt yet. We'll find out why later. This again assumes a 4-DIMM board because that's all I have. I need someone with a 3-DIMM board to test it. As a bonus, there's a big comment block within that illustrates the algorithm. :-) Signed-off-by: Keith Hui <buurin@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5238 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1		2010-03-17 02:15:07 +00:00

README

-------------------------------------------------------------------------------
coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary
BIOS you can find in most of today's computers.

It performs just a little bit of hardware initialization and then executes
one of many possible payloads, e.g. a Linux kernel or a bootloader.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://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:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make
 * python

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')


Building coreboot
-----------------

Please consult http://www.coreboot.org/Build_HOWTO for details.


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.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:
