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...
