Uwe Hermann 328bccc610 Enable onboard VGA on the MS-6178 (i810 chipset) board (trivial). Tested on hardware with the patch from r4398 and works fine as soon as Linux boots (no VGA in FILO for some reason, will investigate). In order to make the 'i810.vga' VGA blob from the vendor BIOS work you have to make the check for PCI device ID mismatches non-fatal (for now) in the src/devices/pci_rom.c file like this: Index: src/devices/pci_rom.c =================================================================== --- src/devices/pci_rom.c (Revision 4393) +++ src/devices/pci_rom.c (Arbeitskopie) @@ -87,7 +87,7 @@ if (dev->vendor != rom_data->vendor \|\| dev->device != rom_data->device) { printk_err("Device or Vendor ID mismatch Vendor %04x, Device %04x\n", rom_data->vendor, rom_data->device); - return NULL; + // return NULL; } printk_spew("PCI ROM Image, Class Code %04x%02x, Code Type %02x\n", The reason is that the VGA blob thinks the proper VGA device ID is 0x7123 whereas it really is 0x7121 on hardware. There are multiple ways to work around this (there have been many discussions in the past), we'll see which method will be used in future... Note: This has been tested against r4393 only for now to make sure there are no problems because of the recent resource allocator changes, see http://www.coreboot.org/pipermail/coreboot/2009-July/050486.html. Tests with trunk will follow.

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
 * perl

Optional:

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


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

Please consult http://www.coreboot.org/Documentation 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:
