Running XP embedded from USB CF.

Hello !

I'm trying to build an XP embedded system and run it
(boot) from an USB compact flash.
I must say, there are a couple of things I've no idea
about how to do...

I've read some texts explaining that I must use EWF, but,
so far, it's no very clear in my mind.
Moreover, I've never found how to modify the boot.ini
file. It's quite easy to install to an other partition,
but what about running from my USB compact flash...

If someone can help me, he/she is wellcome ! :-) !

Thanks & best regards,

Jacques.

Last problem I mentioned was probably related to drive assignment in my
device. This can be easily changed in registry.

This should all apply to USB CF.

If you need EWF then you must mask CF as non-removable. Also if you don't
make XPE boot from USB, you will need to buy IDE CF adapter.

If you choose to do RAM boot from CF. You can leave CF as removable since
you won't need EWF, and also you can boot it from USB.
You will have to add more RAM memory to your device, but increase will be
equal to size of your SDI image.

So you will need to wage what is cheaper and more appropriate solution to
you whether to add more memory, or mark CF - nonremovable and buy IDE
adapter.

Make also sure your board supports USB CF as a boot option.

Will these techniques work with XP (not embedded) or Win2K?

Thanks in advance.

Since you must edit registry offline, they should. But making this work is
hard.

Also since XP writes too much info to disk, and you don't have EWF, this is
not good solution. Since flash has write limitations for every block after
that data will be damaged.
