previously, "normal" initmode relied on the vgarom-based seabios config, which enables option roms, but then lbmk would insert pci-optionrom-exec 0 for vgarom, and 2 for normal in libreboot, coreboot roms with "vgarom" in the filename do pci option rom execution from coreboot, and "normal" roms do execution from seabios(where seabios is the only payload provided on normal setups) this is because payloads like grub can also be used, on vgarom setups, where coreboot must handle oprom execution
