This page describes how to use coreboot on the Intel d945gclf mainboard.

The d945gclf2 is almost the same board as the d945gclf, but with a dual core CPU instead of a single core, an extra USB header and a gigabit network card instead of a 10/100. This board also works fine with coreboot.

SeaBIOS ATA DMA

By default, SeaBIOS uses PIO mode for ATA interfaces. On the ICH7 southbridge, this is very slow. Loading a kernel + initramfs can take up to 20 seconds on this board.

When using ATA DMA mode, this bug disappears. This will have to be set explicitly in the SeaBIOS config file, and selected from coreboot's menuconfig.

From the coreboot root directory, go to payloads/external/SeaBIOS/seabios: <syntaxhighlight lang="bash" inline>cd payloads/external/SeaBIOS/seabios/</syntaxhighlight>

Create a file called .config and add these lines to it:

CONFIG_COREBOOT=y
CONFIG_ATA_DMA=y
CONFIG_VGA_COREBOOT=y

Then, create a full .config file by running: <syntaxhighlight lang="bash" inline>make menuconfig</syntaxhighlight>

Navigate to General Features and make sure the Build Target is set to Build for coreboot.

Navigate to Hardware support and make sure that ATA DMA is enabled [*].

Navigate to VGA ROM and make sure that VGA Hardware Type is set to coreboot linear framebuffer.

Exit menuconfig and save the changes.


It is probably easiest to move the .config file to the coreboot root directory, under a different name (e.g. .seabiosconfig), as coreboot already has its own .config file. <syntaxhighlight lang="bash" inline>mv .config ../../../../.seabiosconfig</syntaxhighlight>

Finally return to the coreboot root directory: <syntaxhighlight lang="bash" inline>cd ../../../../</syntaxhighlight>

coreboot configuration

Create a file called .config and add at least these lines to it:

CONFIG_VENDOR_INTEL=y
CONFIG_BOARD_INTEL_D945GCLF=y
CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT=y
CONFIG_USE_OPTION_TABLE=y

In case you do not want CPU microcode updates included in your ROM, add this line:

CONFIG_CPU_MICROCODE_CBFS_NONE=y

In case you do want to include CPU microcode updates in your ROM, add these lines:

CONFIG_USE_BLOBS=y
CONFIG_CPU_MICROCODE_CBFS_GENERATE=y

By default, serial debugging output is enabled. It is very useful for debugging, but also slows down the boot process a lot. If you don't need serial debug or have no idea how to use it, disable it:

CONFIG_CONSOLE_SERIAL=n

Then, create a full .config file by running: <syntaxhighlight lang="bash" inline>make menuconfig</syntaxhighlight>

Navigate to General setup and make sure that Use CMOS for configuration values is enabled [*].

Navigate to Mainboard and make sure the Mainboard vendor is set to INTEL and the Mainboard model to D945GCLF.

Navigate to Chipset and make sure that Include CPU microcode in CBFS is set to either Generate from tree or Do not include microcode updates.

  • In case you selected Generate from tree, make sure that General setup -> Allow use of binary-only repository is enabled [*].

Navigate to Devices and make sure that Use native graphics initialization is enabled [*].

Navigate to Payload and set your SeaBIOS configuration in SeaBIOS config file.

  • This requires a full path. For instance, if your coreboot root directory is in ~/Downloads, set ~/Downloads/coreboot/.seabiosconfig

Exit menuconfig and save the changes.


Now build your ROM: <syntaxhighlight lang="bash" inline>make</syntaxhighlight>

CMOS default values

By default, the VGA shared RAM on this board is set to 8MB. While this is fine for server use, this is not ideal for desktop or HTPC use.

In order to change CMOS defaults, you will need nvramtool: <syntaxhighlight lang="bash" inline>cd util/nvramtool/ make mv nvramtool ../../nvramtool cd ../../ </syntaxhighlight>

The VGA shared RAM can be increased to 16MB, 32MB or 64MB by running:

<syntaxhighlight lang="bash" inline>./nvramtool -C build/coreboot.rom -w gfx_uma_size=16M</syntaxhighlight> or <syntaxhighlight lang="bash" inline>./nvramtool -C build/coreboot.rom -w gfx_uma_size=32M</syntaxhighlight> or <syntaxhighlight lang="bash" inline>./nvramtool -C build/coreboot.rom -w gfx_uma_size=64M</syntaxhighlight>

Backing up the vendor BIOS

To make a backup of the BIOS chip, run: <syntaxhighlight lang="bash" inline>sudo flashrom -p internal -r bios.rom</syntaxhighlight>

External flashing
