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

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. Doing modprobe kvm-intel yields kvm: no hardware support (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?).
DDR3 N/A
Dual channel support N/A
ECC support  ?
On-board Hardware
On-board IDE 3.5" OK
On-board IDE 2.5" N/A
On-board SATA OK Tested: SATA disk (hda1 in FILO, /dev/sda1 in Linux), but you currently have to use pci=noacpi.
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 WIP The eth1 interface (in this case) works fine, but so far ifconfig -a only shows one of the three NICs (?)
On-board audio WIP Doesn't seem to work, yet.
On-board modem N/A
On-board FireWire Untested
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 WIP Doesn't seem to work properly (at least not with pci=noacpi). A tested PCI NIC appears in ifconfig -a but does not work.
Mini-PCI add-on cards Unknown
PCI-X add-on cards Unknown
AGP graphics cards N/A
PCI Express x1 add-on cards N/A
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 WIP Doesn't seem to work (at least not with pci=noacpi). A tested PCIe VGA card doesn't appear in lspci,
PCI Express x32 add-on cards N/A
HTX add-on cards N/A
Legacy / Super I/O
Floppy  ?
Serial port 1 (COM1) OK
Serial port 2 (COM2)  ?
Parallel port OK Doing modprobe ppdev works, but no further test were performed.
PS/2 keyboard OK
PS/2 mouse OK
Game port N/A
Infrared  ?
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  ?
CAN bus N/A
CPU frequency scaling WIP Needs ACPI. 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).
Other powersaving features N/A
ACPI WIP There's a (partial?) ACPI implementation for this board, but it may need further testing/fixing.
Reboot OK Seems to work fine, even with pci=noacpi.
Poweroff WIP Needs ACPI, thus won't work if you use pci=noacpi.
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 Untested The board supports WOL (tested with vendor BIOS using the wakeonlan utility).
Wake on keyboard Untestede 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 have to use -m kontron:986lcd-m when booted with the vendor BIOS (not needed when booted with coreboot).

Build tutorial

$ 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.

Notes

  • If you use FILO, SATA will probably be hda and hdb, while hdc is the master drive of the IDE controller.
  • Currently you have to use pci=noacpi on the kernel command line to make IDE and SATA work.
  • If you experience kernel crashes (when building without onboard VGA support) try to blacklist the agpgart and intel_agp kernel modules.
  • TODO: Add notes for proper (onboard) VGA setup.
