A client of mine recently purcahsed a graphics workstation. Huge rig, top of
the line hardware. He got 4GB of ram in it, and all 4gb is seen during POST
and BIOS checks. However, Windows XP will only show 3GB installed. I was
able to get it to 'utilize' 3GB with the use of the /3gb switch in boot.ini,
but still... is there any way to get XP pro to utilize all 4gb of ram, or did
he blow a bunch of cash on extra hardware he'll not be able to use?

Thanks in advance

Server 2003 and in Windows XP
