This is a desktop board using intel hardware (circa \~2009, ICH7
|
|
southbridge, similar performance-wise to the ThinkPad X200. It can make
|
|
for quite a nifty desktop. Powered by libreboot.
|
|
|
|
As of Libreboot release 20221214, only SeaBIOS payload is provided in ROMs
|
|
for this board. According to user reports, they work quite well. GRUB was
|
|
always buggy on this board, so it was removed from lbmk.
|
|
|
|
IDE on the board is untested, but it might be possible to use a SATA HDD
|
|
using an IDE SATA adapter. The SATA ports do work, but it's IDE emulation. The
|
|
emulation is slow in DMA mode sia SeaBIOS, so SeaBIOS is configured to use PIO
|
|
mode on this board. This SeaBIOS configuration does not affect the Linux kernel.
|
|
|
|
You need to set a custom MAC address in Linux for the NIC to work.
|
|
In /etc/network/interfaces on debian-based systems like Debian or
|
|
Devuan, this would be in the entry for your NIC:\
|
|
hwaddress ether macaddressgoeshere
|
|
|
|
Alternatively:
|
|
|
|
cbfstool libreboot.rom extract -n rt8168-macaddress -f rt8168-macaddress
|
|
|
|
Modify the MAC address in the file `rt8168-macaddress` and then:
|
|
|
|
cbfstool libreboot.rom remove -n rt8168-macaddress
|
|
cbfstool libreboot.rom add -f rt8168-macaddress -n rt8168-macaddress -t raw
|
|
|
|
Now you have a different MAC address hardcoded. In the above example, the ROM
|
|
image is named `libreboot.rom` for your board. You can find cbfstool
|
|
under `cbutils/` after running the following command
|
|
in the build system:
|
|
|
|
./update trees -b coreboot utils
|
|
|
|
You can learn more about using the build system, lbmk, here:\
|
|
[libreboot build instructions](../build/)
|
|
|
|

**This board is very picky with RAM. If it doesn't boot, try an EHCI debug
|
|
dongle, serial usb adapter and null modem cable, or spkmodem, to get a
|
|
coreboot log to see if it passed raminit.**

Kingston 8 GiB Kit KVR800D2N6/8G with Elpida Chips E2108ABSE-8G-E
|
|
|
|
this is a 2x4GB setup and these work quite well, according to a user on IRC.
|
|
|
|
Nanya NT2GT64U8HD0BY-AD with 2 GiB of NT5TU128M8DE-AD chips works too.
|
|
|
|
Many other modules will probably work just fine, but raminit is very picky on
|
|
this board. Your mileage *will* fluctuate, wildly.
