I'm trying to find an objective overview of embedded xp, all I can
find are either technical how-to articles or marketing waffle.
Basically what I really need to know are things like, how do I know if
my image has become corrupted, how long does it take to distribute the
images, is the system designed so that up to 1000 client can be turned
off everyday, or do they need to be started once and then left on, etc
etc.

Thanks for any help
 
Hi Ron,
how do I know if my image has become corrupted

This would require that you make some way for such check. There is no standard way for this.
how long does it take to distribute the images
Click to expand...
In best case it take time to write image file to disk medium and that you plug that medium in target computer. (For better answer
you will need to provide us with more info)
is the system designed so that up to 1000 client can be turned off everyday, or do they need to be started once and then left on,

What do you mean by this?

Read about RAM EWF it will give you some idea how protection things are working.

Based on your query, I'm going to presume something like PXE network boot

it can take up to 10-15 minutes to load a 256mb SDI file over the net, but
its not particularly pushing the net hard while doing that so a reasonable
server should be able to handle 50 or 60 turn ons without bogging down... if
its more than that at once, you might want to consider a gigabit ethernet
server and having the stations in seperate 100mbit clusters. Worst case
would be to segment your network and have multiple DHCP/RBS/NAT servers that
use a central share for the SDI files. (Each RBS server is also a NAT router
for the stations under its control in this scenario, dual ethernet ports
required)

In any case, I'm a strong proponent of leaving systems on 24/7... the
thermal/electrical shock from turning power on and off is known to
dramatically reduce the lifetime of PC hardware :) Turn the monitor off,
leave the CPU on..

Please note that my setup is a little weird -- I run my RBS server in a VM,
so that 10-15 minute download time may be misleading
 
Rob,

I think to answer all your quesitons you either need to get to know XPe well or consult with a company that does much of XPe work.

Also, this NG archive will help you to get many answers to many question that have been discussed here:
http://groups-beta.google.com/group/microsoft.public.windowsxp.embedded?hl=en&lr=&c2coff=1

From the documentation, however, you can get much information about features (standard XP Pro and EEF - embedded specific) that are
implemented with XPe. You then decide whether and how to use a particular feature.

Anyway, to understand the differences between XPe and XPPro, read this:

An some introductiry to XPe SP2 (high level description of a few features availalble):

My two cents are a bit subjective since how you architect the system will
address some of your questions. If you are using EWF to protect the OS
image, the system is not going to get corrupted on a sudden power down.
There are different methods to distribute an image; these will depend on
what your systems hardware features.
