[time-nuts] My latest Net4501 NTP Server

[Bob Camp]

Hi

The format of the CF card matters a *LOT* to the 4501. A normal Windows
install can recognize more format variations than the 4501 can at boot time.


Some cards work with the 4501 and some cards don't. I've had cards from the
same vendor / same name / same size / same part number come in. The ones
last week work fine. The ones this week - no good. 

The most foolproof way to do it is to PXE boot the 4501 with the card in
place. Then do the install from a CD. 

None of that likely is much help - sorry about that.

Bob

I finally got around to asking this question......I have been working on

Bought the parts a year ago...finally put things together with all of 
the TAPR boards connected to the 4501.

I copied your Ghost image to a 4 GB San Disk CF Card (used Windows to do 
the install)

It appears that the partitions and files are on the CF card but the 4501 
will not boot from the CF card.

Any ideas as to what is going on.
