Do you use windows or Linux? I don't ever face this issue in Linux. Did you remove the Coin Battery when flashing? If you are using Windows, you may try disable Quick startup in power management IDK
Hi everyone, could someone clarify the Coreboot options for a Lenovo M910q? I'm new to this and trying to figure out if it's possible to install Coreboot, or if my only option is to patch the BIOS with Coffee Time. I tried to build Coreboot myself but couldn't find a target for the M910q, only for the M700/M900 Tiny. Any help would be awesome, thanks!
There is no Coreboot for Lenovo M910q/M710q yet. There is Coreboot for M700 / M700 tiny, M900, M920q, M710s for the time being.
For coreboot M710q, I had read though the code but I can't figure out the magic numbers of GPIOs. If someone can help on Coreboot for M710q / M910q, I could be the first one for testing. I got M700 tiny, M710q and a M920q
Never, not once, but that I have a job that eats up my rest, free time and passion
Hi, can you help me with my m700 tiny dump? I wanna put i3 8100T on it.

Am I crazy to want to use an M700 tower motherboard with this mod and an i3-9100 as an OPNsense router for my upcoming 4 or 8 gig FTTH connection?
Hello, first of all, sorry for my bad English, I confess that I am using the translator to ask for help, I followed the topic and it seems to me that it is possible to make an M900 work with an i3 9100t with a Lenovo bios mod, does anyone have these files to make available?
Hello,
I read my M710Q BIOS with 341A, saved that, edited (settings shown at screen shoot) and wrote to BIOS chip.
Did the pin-mod on my 8400T(2 isolate and 2 short), but I have troubles with turning PC on.
I use small piece of aluminium foil, but tried pencil-mode also.
After some tries it turns on, pulls 2.5-3.5 watts from wall and stays like this, sometimes it shorts(?) and turn off after 1 second.
Any idea?

Hi,
I've successfully modded a M910Q with CoffeeTime, I've installed a i5-9500, it works very well, only draws 45W at heavy load. I've changed the PSU for a 90W one to be on the safe side.
Before CoffeeTime:
The dump opened in CoffeeTime:
Once all patchs applied:
Some images of the flash:
After I've flashed the BIOS modded in CoffeeTime, the microcode is now F2 and ME is disabled:
Then I've pinmodded the CPU using this reference:
After installing it and crossing my fingers, it booted after 30 seconds, hurrah!
I have now a i5-9500 working in the M910Q:
Since that, I've bought a M710Q (with Celeron G3900T) and modded it, I'm waiting for a new i5-9500 to install it.
I've made some bench from Celeron G3900T on the M710Q, and the i5-9500 on the M910Q:
CPU-Z shows a gain of 173% in single thread and 462% in multi thread!

I've successfully modded two M710Q the same way than the M910Q, and installed the same CPU (i5-9500).
They're almost exactly the same, the cooler are a bit different, they seems better built on the M710Q.
Here is a photo of the pinmod.
To make the bridge, I used copper tape, bought on Aliexpress. For insulation, I used Kapton tape (real one, not the fake sold on Aliexpress...).
I adjusted the copper tape a little after taking the photo, and it's fine now, both CPU are working perfectly.
