It uses an atom 230, +which is a singe core CPU but it is hyperthreaded so it appears to have +2 thread to the OS. The flash chip is very small, 512KiB, so grub2 does +not fit, which is why libreboot has to use seabios on this target. Full +disk encryption like on other supported targets will not be possible, so +plan accordingly. + +This board has a 945gc chipset which is the desktop equivalent of 945gm +which can be found in the Lenovo x60/t60 or macbook2,1. This chipset +features an ICH7 southbridge. It has 1 DIMM slot that can accommodate up +to 2G of DDR2 RAM. + +Connectivity-wise it has 1 PCI slot, a 10/100 ethernet port, 4 usb slot +and 4 usb ports, with one internal header and 2 SATA ports. + +The D945GCLF2 is an upgraded version of this board. The differences are: +1 more USB header, 10/100/1000 ethernet and a dual core cpu (also +hyperthreaded). Since the board is almost identical (and coreboot code +seem to indicate that it works, since MAX\_CPU=4 is set), it is believed +that it should also work but this is untested. + +Remarks about vendor bios: +-------------------------- + +- Without coreboot/libreboot this board is utery useless, since the + vendor bios is very bad. It cannot boot from any HDD wether it is + connected to the SATA port or USB. With libreboot it works just + fine. + +- The vendor bios write protects the flash so it requires external + flashing to install libreboot on this device. Once libreboot is + flashed there is no problem to update the firmware internally + +Here is an image of the board:\ +\ +Here is an image of the D945GCLF2 board:\ +{width="80%" height="80%"}\ +And SPI SOIC8 flash chip\ +{width="50%" height="50%"} + +How to replace thermal paste and fan +------------------------------------ + +This board comes with very crappy disposable loud fan, that one has no +bearings, which can not be repaired or oiled properly, do not waste your +time trying to fix it, just buy one chinese same size fan\ +{width="50%" height="50%"} +{width="50%" height="50%"}\ +Make sure that new one has same wiring\ +{width="50%" height="50%"}\ +This is a new one, with bearing and maintenable\ +{width="50%" height="50%"} +{width="50%" height="50%"}\ +Now remove the both coolers rotating them a bit, slowly, then clean both +silicons and both coolers (removing cmos battery first is recommended)\ +{width="50%" height="50%"}\ +Put a little bit of non conductive thermal paste on both silicons (only +cpu silicon iis shown on that image)\ +{width="50%" height="50%"}\ + +Before assembling new fan, some need new longer screws, make sure having +these (on the left is original one, too short for new fan)\ +{width="50%" height="50%"}\ +After that, assemble your new fan into CPU cooler\ +{width="50%" height="50%"}\ +Finally assemle both coolers on both chips, do not forget put in the CPU +fan connector back, and you are done. + +Copyright © 2016 Arthur Heymans <arthur@aheymans.xyz>\ +Copyright © 2016 Vitaly Castaño Solana <vita\_cell@hotmail.com>\ +Permission is granted to copy, distribute and/or modify this document +under the terms of the Creative Commons Attribution-ShareAlike 4.0 +International license or any later version published by Creative +Commons; A copy of the license can be found at +[../cc-by-sa-4.0.txt](../cc-by-sa-4.0.txt) + +Updated versions of the license (when available) can be found at +<https://creativecommons.org/licenses/by-sa/4.0/legalcode> + +UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT +POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND +AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND +CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, +OR OTHER.
