I knew that, and I'm talking about lines like these from Makefile:

    25  VIDEO64W=video/video.bios-WINFAST64kb.bin
    26  VIDEO64M=
    27  VIDEO64P=video/video.bios-P6STMT-64kb.bin

    39  build: loader.o bios
    40          cat ${ELF129} ${LOADER} ${PIRQ_M} ${BIOS_B} ${VIDEO64P} > ${PAYLOAD}


I call this hardcode.
Although it is trivial to adapt those lines to a specific board
(that's almost all in patch), I don't think this the right way to do
things.

My patch enables shadow RAM in LinuxBIOS, and doesn't touch  
those registers in ADLO at all.

I don't have a POST card, and connecting or disconnecting keyboard
doesn't help.

Probably LinuxBIOS enables cache on my shadow RAM area,
and it might be a cache problem.
