What I wonder is how many RAM memory is needed for a basic WinXPe, is it the
same as a standard WinXP on a desktop?

Only if you include all functions that XP Pro have.
This question is usefull to know how many memory I will have to add. I will
use the display only for debugging but not when running the application.

Almost impossible to say.
If you would strip it to kernel I guess that even 16 MB or RAM would be enough. But for your case we would need at least to know you
image size.
minlgon/winlogon, services and features that you use, etc.

Hi Fab,

That question you will have to ask them. (Who ever made that image.)

There are EWF considerations, everything else should not take you too much RAM.
But I thought that you made your XP Embedded image and wanted to know what is theoretical RAM minimum that XPe can work on.
If you only need to gather data from hardware and to write data to disk then you could go without Win32 subsystem and make your
kernel image like ~5MB and from your driver do the logging.
RAM memory consumption would be probably same.

hello all,

I will soon have to install a WinXP embedded version on a PC104+ board
including Geode processor/1xLAN/1 display etc.
I will add only some custom PCI board on it.

same as a standard WinXP on a desktop?

I don't know at the moment I'll use an image that is provided "as is". The
image size is around 128Mo, no service is needed, only one application (my
own) will run: read data from custom PCI boards and write to hard drive,
that's all!
Winlogon might be a standard. The image is located here
http://www.compulab.co.il/686-developer.htm (see section WinXP embedded).
The only application that has to run can even be run in a DOS terminal!

Don't care about the RAM memory needed for my application (the more, the
better!), I just want to know an approximate value of RAM that WinXP
require.

Best regards

The generic answer is "same as XP Pro". This can be trimmed slightly
depending on the nature of your build. If you run very few services, etc.
you may be able to do with less. Your mileage may vary (YMMV).

Why XPe then?

Seems like you only need to get an access to hardware (direct or indirect). No fancy Windows UI or process/thread scheduling.
DOS (MS-DOS, PC-DOS, etc.) may help you to accomplish that and do the "hardware" app even faster.
I am not speaking about the DOS image size :-)
 
I MUST use XP because my application need 3-4 threads and the drivers for my
custom board are available only for Win9x and XP.
