4GB RAM allocated to VM but OS only aware of 3GB

Hi All,

I have a new installation of ESX4i on a HP DL380 G5 with 17GB of RAM and 2 x Quad core CPU's.

I have 8 VM's installed with various operating systems (Ubuntu, FreeBSD, Windows XP, Windows Server 2003 and Windows Server 2008 64bit) and the VM's have been allocated 12.5GB of RAM in total. I have an issue with one Windows 2003 server (32bit) VM which is allocated 4Gb of RAM in ESXi but the OS is only aware of 3GB. It is running Citrix Presentation Server 4.5. I have one other VM on that host with 4GB allocated but that one is aware of the whole 4GB - although it is a Windows 2008 64bit VM.

The boot.ini file is below:

timeout=30

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Standard" /noexecute=optout /fastdetect

Does anyone have any idea how I force the VM to see the whole 4GB?

Thanks.

Regards, Thunderbirds.

Presumably NX bit is disabled in the system BIOS then?

Please award points to any useful answer.
