Hi there,
in the last weeks my last two working UltraBooks died. Today I investigated the problem
and obviously in these RDI made notebooks, the NVRAMs not only contain the boot
information,
the host ID and the MAC address but also the hardware configuration.
Hence: Once the NVRAM is completeley dead, absent or replaced, the unit will not
start up any more - it gets stuck in the power on test BEFORE the screen shows any
information.
Do anyone out there have got UltraBooks or UltraBooks IIi up and running? Would
highly be interested in a dump of the NVRAM/Timekeeper!!!
The failed first generation UltraBook are (DS1643 NVRAM):
(*) U20-14-9-512P with three (!!) hard drives, no battery port
(*) U20-14-3-128B two hard drives, battery port
And my beloved UltraBook IIi (TimeKeeper DS1553-070)
(*) U40-14-1X-1024C one harddrive, battery port and creator graphics.
Reply here or PM erik(a)baigar.de,
Thanks

So advice to all owners: Backup your NVRAM contents and I'd be more than happy
to get in touch with you!
Not affected seem to be the PrecisionBooks (e.g. H16-12-8-512L2, two hard-
drives and battery port) as they do not contain an NVRAM/TimeKeeper.
