It takes some skill to extract a vgabios from official BIOS image, in
some cases (for some types of the official BIOS) it is hardly doable.
I recommend that you follow this path -

Install the official BIOS image again, then boot Linux
Good day! While building the coreboot's toolchain by using GCC 7.1.1
version, I am getting the following error:
ubsan.c:1474:23: error: ISO C++ forbids comparison between pointer and

|| xloc.file == '\0' || xloc.file[0] == '\xff'
The fix is very simple - just open
Dear coreboot/flashrom mailing list members,
As you may have noticed it is not that easy or straightforward to gain the
edit rights for coreboot/flashrom wikipedias so the people are mass
migrating to the unofficial wikis. For example: recently Zoran Stojsavljevic
had to bring his Coreboot/VBT
Before investigating the software methods, in this situation I would have
tried to: using some great thermal paste, cleaning the dust, and - most
likely - switching to a manual fan control: there are the hardware fan
control adapters, and if you don't have those - temporarily you could just
wire
As far as I know, AMD does not have any "evil brother" of Intel ME. It only
has AMD PSP (Platform Secure Processor) that is built-in to CPU. So, I
don't think that cutting a PCH from AMD CPU has any practical value: even
if the platform will boot after such a radical change to computer's
hardware,
Hi Taiidan, try following these instructions:
1) download the latest official BIOS update .exe file from your laptop
manufacturer's website (Lenovo in this case)
2) open this .exe file with 7zip utility and extract all its' contents to a

It should be possible to reflash EC internal firmware through a keyboard
port, - or maybe through some other debug port that may or may not be
soldered by default... For example, here is a guide that describes how to
reflash EC KB9012 internal firmware on Lenovo G505S - "AMD based laptop

Inside the " payloads/coreinfo/coreinfo.c " file, at lines 290 - 296 there
is a code:
int main(void) {
int i, j;

It could be that your board has CONFIG_LP_USB option disabled at libpayload
config. If you are unsure about how to check it, you
Hi, i took my results from this page (could use google translate) -

>From your 1st test, Grizzly is better by 0.33 C , and from your 2nd test -
by 0.31
Actually there is an even better non-conductive thermal paste (not liquid
metal) than "Grizzly" --- it is called " Gelid GC-Extreme ". Here is a
comparison from one review website that I screenshotted -

between them is not big,
Hi Chris, you could read this article, it describes the laptop BIOS
flashing procedure in a great detail:

Although it is written with Bus Pirate programmer in mind, other
programmers like cheap CH341A have almost the same
I have successfully built and added FILO bootloader to my Lenovo G505S
