Introduction
|
||
|
============
|
||
|
|
||
|
This board is a mini-itx desktop board for 2008. 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 whether 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
|
||
|
|
||
|

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\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_141620.jpg){width="50%" height="50%"}
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_141614.jpg){width="50%" height="50%"}\
|
||
|
Make sure that new one has same wiring\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_142618.jpg){width="50%" height="50%"}\
|
||
|
This is a new one, with bearing and maintenable\
|
||
|

|
||
|
Now remove the both coolers rotating them a bit, slowly, then clean both
|
||
|
silicons and both coolers (removing cmos battery first is recommended)\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_141601.jpg){width="50%" height="50%"}\
|
||
|
Put a little bit of non conductive thermal paste on both silicons (only
|
||
|
cpu silicon iis shown on that image)\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_142031.jpg){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)\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_141659.jpg){width="50%" height="50%"}\
|
||
|
After that, assemble your new fan into CPU cooler\
|
||
|
![](https://av.libreboot.org/d945gclf/20160923_141635.jpg){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.
