Did some experiments in removing/swapping NVRAMs and none of my UltraBooks is reaching the OpenFirmware or even turning on the backlight/LCD, so I have no way of trying to read the NVRAM contents from there :-(
Symptoms (i.e. behaviour of the LCD display) of the UltraBooks differ with contents of NVRAM or if there is no NVRAM at all. So without some known-valid NVRAM contents I fear I am lost :-( Symtpoms I see: Power symbols coming up always then (a) only tock-tock from speaker (b) blank, only the inverse A flashing several times, later a single time again and then blank forever (c) heart beat and speaker flashing, later the inverse A coming on as well. Can anyone out there at least tell me what their LCDis showing during startup? I will archive the contents of the NVRAMs as they are now although they are probably not of much use...
