AMD RS780 uma graphics. Tested with frame buffer sizes 64m through 1GB by running dxdiag and Windows media player at 1600x1200 true color. Additional changes needed to boot Win7 on Mahogany_fam10 will follow. -- Enable and program the debug bar as required by the ATI graphics driver. First, make the debug bar writable and allow resource allocation code to program it. Once programmed, enable its operation. -- Disable the family 10h processor mmconf while the RS780 mmconf is in use. -- Make strap programming more closely follow the reference BIOS. -- Disable PCIe bar 3 after using it. -- UMA size is no longer hardcoded. -- Disable write combining for all steppings to eliminate stability problem. -- Correct task file data. -- Improve the accuracy of the Atom table that passes information to the driver.

------------------------------------------------------------------------------- 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 Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) 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: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
