% Intel D945GCLF desktop board
If you just want flashing instructions, go to
[../install/d945gclf.html](https://libreboot.org/docs/install/d945gclf.html)
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 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

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.
