Hi Mike,

I edit the low below for brevity.

The issue you're facing is simple, but you might have to do a bit of
work to fix it. You need special handling code for the flash boot block
write protection on your board, commonly called board_enable. Don't
worry, we can help you with that.

First, do you know how the ROM image was flashed in the first place?
flashrom? flash_and_burn? lbflash? /dev/bios? That will help us find any
existing source code and save us the trouble of toggling loads of GPIOs.

The output of "superiotool -dV" will be useful as well.
