So, as far as I understand, you ended up flashing both chips?

Re: HP Elitebook 840 G2

Hi all! I'm trying to flash a modified BIOS. The flash itself succeeds, but when I install the chip in the motherboard and turn on the laptop, the bios (or some service) runs an automatic recovery tool due to "bios corrupt" or the checksum is wrong. As a result, I have an old bios.
1) Can anyone help me avoid or disable the automatic recovery?
2) I suspect I need to flash the second chip on the motherboard as well, the one 2Mb
But how to create and write the right checksum?
