i have 2 gigs of ram installed but applications wont launch once 1 gig is
used up.

The performance monitor never shows more then 1 gig of memroy used up, yet
applications wont launch when its near the 1 gig of used memory. how to free
up that other gig so that I can use 2 gigs of ram instead of 1. Its like i
have 2 gigs of ram and 1 gig is wasted. also, why dont applications launch?
do i need to configure some swap space or something to ensure applications
launch?

Hope we are talking about running an app on XP Embedded target.

You should probably first analyze when the application cannot start. Use tools like RegMon/FileMon/Process Monitor and etc. if you
want to know more about the app. If you happened to have the app sources, Remote Debugging can help you to see what's going on wrong
with the app launch.

Not sure about the 2-nd Gig your app can't use but there is a technology (PAE) supported on XP and a boot.ini switch that allow apps
to use 3rd Gig: http://www.microsoft.com/whdc/system...AE/PAEmem.mspx
