Uniflash works with everything because it does 16bit calls into the bios
image to enable flash writes. We can't really do that (or: heavily try
to avoid that) in Linux(BIOS)

I am putting my efforts in the flashrom utility of LinuxBIOS instead and
I want to drop devbios once flashrom handles everything it needs to

Can you try to get devbios work (whether it finds the chip. no flashing

You may want to look at the asus bios flashing hooks to find out what
they do. Be sure it is legal in your country to analyze foreign code
