Hello, There is a very likely chance in your situation that flashrom will be able to read and write to the chip even if it's not on the supported chips list. This command simply identifies the chip and tells you if everything is working.
flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=2000 -V You might get some error about how you might not be able to write to the chip, but from my experience with an ASUS BIOS chip and a Raspberry Pi, this was still possible. https://www.rototron.info/recover-bricked-bios-using-flashrom-on-a-raspberry-pi/ On 2019-08-05 4:39 p.m., Shaver,Zachary J wrote: > Hey, > > I'm considering using flashrom to upgrade the bios on a MSI B450M Pro-M2 > Motherboard.
