Thank you for your reply, KM.
I did exactly what you talked here. After I set the Registry, I could see the envirnment variable "DEVMGR_SHOW_NONPRESENT_DEVICES=1" by typing "set" in DOS Prompt Window. However, I really couldn't see "Non-plug and Play Drivers" in devmgr
I do have a few devices without drivers installed, so every time when I reboot the machine, it pops up window to show that OS found new devices. On the same hard disk and on the same machine, I have another partition on which Windows XP Professional was installed. Same as Windows XP Embedded, I didn't install drivers on these devices. But I could see "Non-plug and Play Drivers" on Windows XP Professional on the same machine and with the same devices. Since we'll make our own drivers for these devices later for Windows XP Embedded and they are going to be shown in "Non-plug and Play Drivers", this is why I'm looking for it. At least, I should be able to see "Non-plug and Play Drivers" like "Beep", "Null"
Will those devices affect the "Non-plug and Play Drivers"? I don't know. But I could see "Non-plug and Play Drivers" on Windows XP Professional on the same machine. So I guess there could be something I missed in Windows XP Embedded or some settings I did do properly
I'm looking forward to hearing from you, and thanks again for both of you

That should work. What actually Doug meant was setting th
DEVMGR_SHOW_NONPRESENT_DEVICES environmental variable to "1". Device Manage
(devmgr.dll) will pick the var value up and display hidden devices, non-Plu
and Play devices, and devices not attached to the computer (commonly know
as "ghosted" or "phantom" devices)
Instead you may just try to run the following commands from Command Lin
Prompt box
set DEVMGR_SHOW_NONPRESENT_DEVICES=
start devmgmt.ms
Select "Show hidden devices" option and see if it helps

path. I searched all of Registries under "HKEY_LOCAL_MACHINE" and I stil
couldn't find it. So I created a new Registry with this name and value. I
doesn't help, either, I still couldn't see the "Non-plug and Play Drivers
in Device Manager
