An option rom which the BIOS will load can be as simple as

        org 0x0
signature:
        db 0x55
        db 0xaa
size:
        db 0x01 ; fixme
entry:
        jmp start
start:
loop:
        jmp loop

nasm -o test.rom test.asm
will produce the option rom called test.rom which needs its checksum corrected.
biossums from vgabios can be used for this.

The option rom will be loaded with the following config:
optromimage1: file=test.rom, address=0xd0000
