Fedora core 3 - 4GB memory limit?

[Eric Persson <eric@xxxxxxxxxx>]

Hi,

I have a Fedora core 3 machine:

Fedora Core release 3 (Heidelberg)
Linux localhost.localdomain 2.6.9-1.667smp #1 SMP Tue Nov 2 14:59:52 EST 
2004 i686 i686 i386 GNU/Linux

It currently have 3gb of memory in it, and I have two spare slots which 
I intend to fill with an additional 2gb of memory to get to a total of 
5gb in the machine.

Is this possible or is there a 4gb limit in the kernel, which would make 
something like PAE needed. If so, is that already included in the stock 
kernel used?

Any other apparent caveats?

Thanks,
	Eric
