Hi Erik,
I just happen to have mine out and took a quick video of boot up. Mine
does not have a floppy drive or hard drive (I don't have a caddy) so it
boots pretty quickly to the "ok" prompt but you can see the LCD display and
when the LCD comes up.
Here's a quick video.

On another note: Still hoping to find an Ultrabook hard drive caddy if
anyone has a spare or even internal pictures to see if it has any smarts or
if it's just an EIDE drive that goes pin-for-pin to the internal 40 pin
SCSI-5 connector. I've been checking eBay for years now :(
Hope this helps,
Santo

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...
