>1. The trick to flashing firmware on openbsd is understanding that openbsd as part of it's normal boot shuts off a lot of memory access(sysctl kern.securelevel). so the easiest way is boot into single user mode so flashrom can write to the correct memory addresses. This is an excellent point! Flashrom + runlevel 1 in most linux/unix'es = best chance to read/write BIOS/(U)EFI ((E)EP)ROM/flash... Also, +1 for OpenBSD.
