Max Memory SQL2K EE on W2K3 EE

This is what I have
Windows Server 2003 Enterprise Edition (x86)
SQL Server 2000 Enterprise Edition (x86)
What I'm trying to clarify is if I have a W2K3 EE system with 32GB of RAM
can a single instanace of SQL2K EE access the entire 32GB
or
Will the single instance only access 8GB and therefore only if I had 4
instances would SQL Server use 32GB
Thanks,
PaulSP3 and higher will address 32 GB of RAM on W2k3EE. I wouldn't set total
SQL memory for all instances higher than 28GB on such a system. Setting
memory higher can starve necessary OS functions like AWE mapping which will
kill performance and stability

I've looked through the release notes for SP3 and can't find any reference
to this.
Have you seen this documented somewhere or is your answer based on a system
you have worked with?

Have you been involved with a system running W2K3 EE and SQL2K EE with a
large amount of RAM?
