Hi all,

thanks for your answers and sory for the late response (vacancies)

Unfortunately my video BIOS is 128K in size and I couldn't fit it into my 2M 
flash eprom together with ADLO and LinuxBIOS. So I tried the builtin support 
first.
I was able to compile everything OK after either leaving out FRAMEBUFFER=1 in 
the config file or copying the function framebuffer_on from 
northbridge/intel/440GX/northbridge.c to the same file in 
northbridge/intel/440BX

During boot I get the following log on the serial console:
