Winbond 25q32bvsig. ch341a programmer.
I'm not sure that i have a good backup, or maybe the bios don't have a good connection to the programmer.

to make a correct reading and writing of the bios chip ... the bios chip is removed from the motherboard and stuck on the programmer
in the absence of an adapter, or wires are pulled from the chip to the programmer,
the clip is not used because most of the time it gives errors..
use one of these two programs..
