If you can, connect up a serial terminal, or a PC running a terminal 
program, and set it to 9600 bps, 7 bits, even parity. When you turn on 
the machine, see what sort of output you get, if any, on the terminal.

It's possible that the NVRAM is defaulting to the serial port for the 
console device.

To configure the LX to boot off it's internal disk, all you need to do is
type 'setenv boot-device disk'. To check that it's been set properly, type
'printenv' and look at what it says for 'boot-device'. Also check that
'diag-switch?' is set to false, otherwise it will default to the serial
port for the console regardless of the settings of 'output-device'. 

Regards,

Craig.
