The default console device is configured in location 0x1F of the EEPROM. 
To use a b&w frame buffer, this location needs to be set to 0x00. 

The console will also default to using the serial port if no framebuffer
is available at all and no keyboard is plugged in, but this doesn't apply
to your system, although it's handy to know for debugging if something
goes wrong. 

Also check the diag switch is not set in diag mode, because this forces
the console to serial port A regardless of the EEPROM setting. Make sure 
it's set to 'norm'.

Regards,

Craig.
