On-board VGA	OK=lime | TODO=red | No=red | WIP=orange | Untested=yellow | N/A=lightgray | yellow }}" | OK	You need to prepend the VGA blob from the proprietary BIOS for this to work. Console works, X11 works (use the intel X.org driver).

Build tutorial (without onboard VGA)

$ svn co svn://coreboot.org/repos/trunk/coreboot-v2
$ cd coreboot-v2/targets
$ ./buildtarget kontron/986lcd-m
$ cd kontron/986lcd-m/kontron_986lcd_m

Now copy your payload into the current directory and name it payload.elf. Then:

$ make -s

The resulting coreboot.rom is your coreboot ROM image you can flash using flashrom.

Build tutorial (with onboard VGA)

$ svn co svn://coreboot.org/repos/trunk/coreboot-v2
$ cd coreboot-v2/targets

In order to use on-board VGA you have to use the VGA blob from the vendor BIOS, and modify the coreboot config files a bit. Edit src/mainboard/kontron/986lcd-m/Config.lb in the section starting with chip drivers/pci/onboard. Depending on whether you use a 1 MB, 512 KB, or 256 KB ROM chip, you'll have to set the correct rom_address value:

chip drivers/pci/onboard
  device pci 02.0 on end # vga controller
  # register "rom_address" = "0xfffc0000" # 256 KB image
  # register "rom_address" = "0xfff80000" # 512 KB image
  register "rom_address" = "0xfff00000"   # 1 MB image
end

Then, you have to obtain the VGA blob from the vendor BIOS. Thus, get the original vendor BIOS image using Flashrom:

$ flashrom -r kontron.dd

You can list all components of the vendor BIOS via the amideco utility (apt-get install amideco on Debian systems):

$ amideco kontron.dd -l

The file we need is the 64KB VGA blob named amipci_01.20:

$ ls
amibody.04  amibody.0e  amibody.1a  amibody.2e    amipci_01.20
amibody.06  amibody.11  amibody.1b  amibody.80    amipci_02.20
amibody.08  amibody.18  amibody.21  amibody.90    kontron.dd
amibody.0c  amibody.19  amibody.2a  amipci_00.20

In order to use onboard VGA you further need to edit targets/kontron/986lcd-m/Config.lb. Comment out the line

option ROM_SIZE = 1024 * 1024

and enable the line

option ROM_SIZE = (1024 * 1024) - (64 * 1024)

instead (we're assuming a 1 MB ROM chip here, change that if you use another size). This will leave 64 KB room in the coreboot ROM image. We can now build coreboot as usual:

$ ./buildtarget kontron/986lcd-m
$ cd kontron/986lcd-m/kontron_986lcd_m

Now copy your payload into the current directory and name it payload.elf. Then:

$ make -s

Finally, prepend the 64 KB VGA blob to the coreboot image:

$ cat amipci_01.20 coreboot.rom > coreboot_final.rom

The resulting coreboot_final.rom is your coreboot ROM image you can flash using flashrom.

Notes

• If you use FILO, SATA will probably be hda and hdb, while hdc is the master drive of the IDE controller.
• If you experience kernel crashes (when building without onboard VGA support) try to blacklist the agpgart and intel_agp kernel modules.
