If it is ok to mix them - Which slot should the 512 go into and which should the 128 go in to. i have a compaq Pressario 7000 - if that helps -- it is a compaq mobo i think -- if that helps to answer the question any.
Like David said, you should be ok mixing different Ram sizes, but check first to see how much your mobo can handle. If you need a program to help you see how much your mobo can handle, then THIS
is a good one.
Also, dont forget that when you buy the Ram, get the same speed e.t.c. Ram as you already have, so PC2100 in your case, this should bring performance levels up
Hope this helps
