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!
|L1 cache enabled||Unknown||How to test ?|

|SDRAM||OK||It appears to work since it boots successfully.|
|Dual channel support||N/A|
|On-board IDE 3.5"||N/A|
|On-board IDE 2.5"||Untested||Testing it requires a 2.5"<->2.5" IDE cable|
|On-board USB||OK||Works in GNU/Linux but not in SeaBIOS.|
|On-board VGA||Unknown||Has support in the linux kernel(untested) and in SeaBIOS VGA option roms(tested too rapidely, wasn't executed somehow)|
|On-board Ethernet||OK||Works in GNU/Linux|
|On-board Audio||OK||Tested with MPD under parabola|

|PCI add-on cards||OK||Booted successfully from a 3com PCI card with ipxe, also tested with an ath9k, works fine|
|Mini-PCI add-on cards||OK||tested with an ath5k, works fine|
|Mini-PCI-Express add-on cards||Unknown|

|Legacy / Super I/O|
|Serial port 1 (COM1)||OK||DE-9|
|Serial port 2 (COM2)||OK||10 pins header|
|PS/2 keyboard||Unknown||Not detected in coreboot, may work in GNU/Linux|
|Sensors / fan control||Unknown||Are there some sensors?|
|Hardware watchdog||Unknown||Is there a watchdog?|
|SMBus||Unknown||Is there an i2c bus? i2cdetect should tell. Since there is a VGA connector, there should at least be a bus that goes on the DCC pin.|
|CPU frequency scaling||Unknown||Does the geode support cpufreq?|
|Other powersaving features||Unknown||What other powersave feature there should be?|
|ACPI||No||ACPI tables are not implemented, and not available in make menuconfig|
|Reboot||OK||tested with the reboot command under parabola(systemd based)|
|Poweroff||Unknown||How to test? Probably by wiring the power button ?|
|High precision event timers (HPET)||Unknown||Does the board have such timer ?|
|Random number generator (RNG)||Unknown||Does the geode have a hardware RNG ?|
|Wake on modem ring||Unknown||Is there wake on modem on this board ?|
|Wake on LAN||Unknown||Is there wake on lan on this board?|
|Wake on keyboard||Unknown||Is there wake on keyboard on this board?|
|Wake on mouse||Unknown||Is there wake on mouse on this board?|
|Flashrom||OK||Works in coreboot, be sure to run "modprobe msr" before.|
Proprietary componemts status
- VSA: LGPL but require a microsoft compiler. Code need to be converted, openvsa froze the board during boot(but it was tried with my distro's compiler).
- Has a free video option rom that can be generated by seabios, i didn't succeed at getting it work.
- Retest the following: Audio, Second serial port, USB under GNU/Linux, they were tested with an old revision, before the board status system.
- Test untested things in "Status"
- Make fallback mecanism compile and work.
- Add ACPI support and make seabios detect the USB hard disks at boot.
- Compatible with nvramtool.
- There is an LPC dongle with a socketed second BIOS chip in it, it can probably be bought, lent or given by the company making the card.
USB doesn't work under SeaBIOS with this board, so pressing F12 from an USB keyboard to boot on an USB key won't work for now.
- If you have no compact flash reader, you add ipxe and sgabios to the coreboot image in order to boot from the network. Sgabios is needed to be able to press F12 in SeaBIOS trough the serial port.
- SeaBIOS do run external option roms, like the ones on network cards.
- Removing the compact flash card before SeaBIOS makes SeaBIOS boot on the next available device (like a network card with ipxe), and putting it back before the linux kenrel boot makes it appear under GNU/Linux.
