4Gb Support under Vista 32Bits

Hello Everybody (Sorry by advance for my poor English, I'm french [nobody is
perfect]),

I have Vista 32Bits Premium (PAE Enabled) together with :
Asus P5K (Normal),
4GB Kingston HyperX (Bios Feature Memory Remap enabled),
Q6600/B3,
Antec Trio 650Watts,
nVidia 7900GS.

Bios does see 4GB, Vista does see 3.25GB, which I understand is normal
because Vista cannot address more 4GB. This 4GB include RAM, Video Memory
and Hadware space.

At office we have Windows Server 2003 Std 32Bits (PAE Enabled) together with
:
Asus P5W-DH Deluxe,
4GB Memory (Bios Feature Memory Remap enabled),
Q6600/B3.

Bios does see 4GB. Win2K3 does see 4GB.

Can somebody explain me the difference between Vista and 2K3 behavior, in
handling 4GB Physical RAM ?
Is that HAL issue ?

Is there a possibility tu use under Vista 4GB physical RAM. PAE is enabled
so 36Bits addressing should be possible like in 2K3 Std.

Thank's for help/information.

François.

Already Checked before posting.

Sorry, I do not understand why it explains the difference of behavior :
"Support for PAE is provided under Windows 2000 and 32-bit versions of
Windows XP and Windows Server 2003"
