W2k3 server and 3 GB RAM limit

I have HP desktop and installed there Windows Server 2003 R2 Ent Ed. x64.
BIOS can see all 4 GB of RAM, but Windows can see only 3,06 GB. Wit PAE
switch at the end of boot.ini - there is the same.

How can I exted to all 4 GB? Server is x64 and EE.

That's quite common with workstation hardware. The motherboard uses some of
the address space below 4GB for peripherals. If the motherboard supports
more than 4GB of RAM there may an option in the BIOS to remap this above the
4GB barrier. If not, you're stuck with what you have.

Every BIOS seems to implement this differently. You have to go through all
the BIOS settings looking for one that mentions something about memory
remapping, memory hole, sometimes it mentions OS/2 on older BIOSs. It's a
bit of trial and error. You could also contact HP support.

BIOS recognized all 4 GB of RAM. What should I setup more...?
