== 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.
 +
 +
== Boot speed ==
 +
 +
This is a non-scientific, quick'n'dirty boot speed measurement using coreboot v2 (r4341) + FILO trunk (r98) and the vendor BIOS, where coreboot was configured with no serial output (loglevel 0).

Although coreboot is ca. 6 seconds faster at the GRUB prompt, the "Loading initrd" part of the Linux kernel booting seems to take longer than on the vendor BIOS. This should be investigated.

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

This page describes how to use coreboot on the Kontron 986LCD-M/mITX mainboard. It is maintained by Uwe Hermann.

The mainboard's manual (PDF) is available from the vendor website (together with various other documents).

A sample boot log from this board is available in the mailing list archive.

[edit] Status

Device/functionality Status Comments
CPU
CPU works OK Intel(R) Core(TM)2 CPU T5300 @ 1.73GHz (dual core)
L1 cache enabled OK CPU: L1 I cache: 32K, L1 D cache: 32K
L2 cache enabled OK L2 cache: 2048K
L3 cache enabled N/A
Multiple CPU support N/A
Multi-core support OK Both cores show up in /proc/cpuinfo.
Hardware virtualization Untested Hardware virtualization is not supported by this CPU (modprobe kvm-intel fails on coreboot + vendor BIOS).
RAM
EDO N/A
SDRAM N/A
SO-DIMM N/A
DDR N/A
DDR2 OK Works fine, but currently you need to populate both RAM slots with DIMMs of the same size (and reasonably similar timing probably: The controller has to operate in Dual Channel mode for now).
DDR3 N/A
Dual channel support OK Works fine according to memtest86+ (Tested: 2x 1GB DIMMs, interleaved mode).
ECC support N/A
On-board Hardware
On-board IDE 3.5" OK
On-board IDE 2.5" N/A
On-board SATA OK Tested: SATA disk ((hd0,0) / hda1 in FILO, /dev/sda1 in Linux).
On-board SCSI N/A
On-board USB OK Tested: USB thumb drive in all 4 backpanel USB ports, as well as on the USB pin headers on the board (USB6_7, see manual).
On-board VGA 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).
On-board ethernet OK All three NICs show up correctly in ifconfig -a and work fine.
On-board audio OK Works fine.
On-board modem N/A
On-board FireWire OK Seems to work fine (backpanel FireWire port), even with pci=noacpi. Tested using the eth1394 module for IPv4-over-FireWire. The FireWire pinheader IEEE1394_1 (see manual) is not yet well-tested.
On-board smartcard reader N/A
On-board CompactFlash OK There's an onboard CompactFlash slot on the back-side of the board. FILO sees it as (hd2,0) / hdc1, Linux as /dev/sdb1.
On-board PCMCIA N/A
Add-on slots/cards
ISA add-on cards N/A
Audio/Modem-Riser (AMR/CNR) cards N/A
PCI add-on cards OK Works fine, tested with a PCI network card.
Mini-PCI add-on cards Untested
PCI-X add-on cards N/A
AGP graphics cards N/A
PCI Express x1 add-on cards OK Works fine with PCIe x1 network card in x16 slot
PCI Express x2 add-on cards N/A
PCI Express x4 add-on cards N/A
PCI Express x8 add-on cards N/A
PCI Express x16 add-on cards OK Works fine, tested with an Nvidia x16 graphics card
PCI Express x32 add-on cards N/A
HTX add-on cards N/A
Legacy / Super I/O
Floppy N/A
Serial port 1 (COM1) OK
Serial port 2 (COM2) Untested There are also COM3 and COM4 pin headers on this board.
Parallel port OK Doing modprobe ppdev works, but no further test were performed. You probably need a special cable to connect to the onboard pin-header.
PS/2 keyboard OK
PS/2 mouse OK
Game port N/A
Infrared Untested
PC speaker OK
DiskOnChip N/A
Miscellaneous
Sensors / fan control OK Works fine using the w83627hf, coretemp (and also i2c-dev, i2c-i810, and eeprom) Linux kernel modules.
Hardware watchdog OK Not yet actually tested, but it seems to be found: iTCO_wdt: Found a ICH7 or ICH7R TCO device (Version=2, TCOBASE=0x0560).
SMBus Untested
CAN bus N/A
CPU frequency scaling WIP With pci=noacpi the cpufreq-info utility doesn't output anything useful. On vendor BIOS you can use p4-clockmod (discouraged) or acpi-cpufreq (iff you enabled the respective option in the BIOS menu). On coreboot with ACPI, you can modprobe p4-clockmod successfully (but not acpi-cpufreq), but it's unclear if it really works correctly.
Other powersaving features N/A
ACPI OK
Reboot OK Seems to work fine, even with pci=noacpi.
Poweroff OK Works fine.
Suspend Unknown
Nonstandard LEDs N/A
High precision event timers (HPET) OK The HPET is detected by Linux (hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0) and powertop output suggests that it works ok.
Random number generator (RNG) N/A
Wake on modem ring N/A
Wake on LAN OK Works fine. Tested using the wakeonlan utility.
Wake on keyboard Untested Works fine with vendor BIOS.
Wake on mouse N/A Doesn't seem to be supported (by the hardware / vendor BIOS), tested with a PS/2 mouse, as well as with a USB mouse.
Flashrom OK Works fine, but you might need -m kontron:986lcd-m when booted with the vendor BIOS (not needed when booted with coreboot).

[edit] Build tutorial (with onboard VGA) 

$ svn co svn://coreboot.org/coreboot/trunk coreboot
$ cd coreboot
$ make menuconfig

In the payload menu change the settings like follows: 

       Add a payload (An ELF executable payload)  --->
   (payload.elf) Payload path and filename
   [*] Use LZMA compression for payloads


To add a VGABIOS image to the CBFS image go to the VGA BIOS submenu and change the settings to the following: 

   [*] Add a VGA BIOS image
   (amipci_01.20) VGA BIOS path and filename
   (8086,27a2) VGA device PCI IDs

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

$ make


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


[edit] Getting the VGABIOS image

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

[edit] 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.

[edit] Boot speed

This is a non-scientific, quick'n'dirty boot speed measurement using coreboot v2 (r4341) + FILO trunk (r98) and the vendor BIOS, where coreboot was configured with no serial output (loglevel 0).

BIOS Power-up — GRUB Power-up — Linux login prompt
Vendor BIOS (boot from SATA disk) 13.1s 38.8
coreboot (boot from SATA disk) 7.3s 37.9

Although coreboot is ca. 6 seconds faster at the GRUB prompt, the "Loading initrd" part of the Linux kernel booting seems to take longer than on the vendor BIOS. This should be investigated.
