Hello,

I am contacting you because a year and a few months ago, I bought a PC assembled by the company NovaCustom (model NH77) and I would like to know if I can install Coreboot as a BIOS without risk for my PC.

I specify that I did not find the "official" name of my motherboard (which is, according to my current BIOS - InsydeH20 - NH5x_7xDPx). When I go to my Windows 11 (in the msinfo32 tool), the manufacturer of my motherboard would be "Notebook".

Here is the result of the commands you wanted to be addressed for any such questions:

flashrom is free software, get the source code at https://flashrom.org

flashrom was built with libpci 3.7.0, GCC 11.2.0, little endian
Command line (3 args): flashrom -p internal -V

W836xx enter config mode worked or we were already in config mode. W836xx leave config mode had no effect.
Active config mode, unknown reg 0x20 ID: 55.
WARNING: No chipset found. Flash detection will most likely fail.
========================================================================
You may be running flashrom on an unknown laptop. We could not
detect this for sure because your vendor has not set up the SMBIOS
tables correctly. Some internal buses have been disabled for
safety reasons. You can enforce using all buses by adding
  -p internal:laptop=this_is_not_a_laptop
to the command line, but please read the following warning if you
are not sure.

Laptops, notebooks and netbooks are difficult to support and we
recommend to use the vendor flashing utility. The embedded controller
(EC) in these machines often interacts badly with flashing.
See the manpage and https://flashrom.org/Laptops for details.

If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
========================================================================
The following protocols are supported: None.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
