Hello
I would be very happy to help with pictures, source, binaries, info etc.
But since Denver, I have been just a bit behind. Too many side projects :-)
Anyway, I will get back in touch soon. If you use my previously released
binary, you should be fine.

Hello
I am new to coreboot. I tried to run coreboot on my Thinkpad W520 to
replace my Sandy Bridge CPU by a Ivy Bridge CPU, since several people
reported it worked very well.
Following their suggestions, I simply tried to flash a T520 image to
save time. It didn't work at all. I was very angry I

Thanks a lot for the documentation the detailed the explaination!

So I did many more tests today (more than 6h, and flashing around 30
times), with SPD settings hardcoded into raminit, and without the mrc cache
interfering.
TLDR: coreboot tries to increase the frequency without increasing the
voltage, and that doesn't work for all memory.
Basically, with the pr

With the cross compiling tool chain, coreboot takes 1G. If you are a bit
short on space, or if you want to save writes to your SSD, instead of
having multiple copies of the coreboot source folder, I have found out
overlayfs is very practical.
If you have done git clone in /opt/coreboot/src/

The USB3 on a W520 is provided by a uPD7020200 on PCIe port 7, so I just

Yet in the boot I was getting:

Since I started using coreboot, I have noticed my battery doesn't seem to

that I use to compare power consumption, so I decided to verify if my
perception was true. After some quick tests, I noticed the power profile

The correct timings are detected by X (cf below), so I checked the

wrong.

I am still interested in lowering the power consumption. To try to find the
culprit, I am thinking about monitoring temperature sensors.

S2: GBE
S3: WWAN
S4: DIMM(TOP)
S5: DIMM(BOTTOM)

I see recommendations for a X230, but I disagree. If you really want the
best, it's a W520 or a W530.
In either, you can have 32G of Ram, and you can replace the default CPU
with a Intel i7 3940XM cpu. But only on the W520 you will have a full size
display port and (more important) an eSATAp conne
Addressing over 8G is not supported by the chipset used on nehalem thinkpad

Stupid limitation, but it is not the CPU fault.
