Nope it's not going to support anything more than 1GB.
But that mobo according to HP supports upto 2 GB max.http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00069442
So what you can do is certainly buy 2x 1GB sticks of the RAM specified there and upgrade it.
You can also lay your hands on a cheap AGP old GeForce4 GPU and make the max out of that system for quiet some time if you want to hang on to it and still be in good shape.[/quotemsg
Thanks i will look into this the print out shows 1gb max 2x512 but i would love to put 2x1gb sticks
