The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
|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).|
|DDR2||OK||Works fine, but currently you need to populate both RAM slots with DIMMs (of the same size?).|
|Dual channel support||N/A|
|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 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 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 SD card reader||N/A|
|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|
|Mini-PCI-Express 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|
|Serial port 1 (COM1)||OK|
|Serial port 2 (COM2)||?|
|Parallel port||OK||Doing modprobe ppdev works, but no further test were performed.|
|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).|
|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.|
|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).|
$ 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.
- 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.
