There's a fairly technical article, but does explain some of the basics here. http://www.microsoft.com/whdc/system/platform/server/PAE/pae _os.mspx Unfortunately you would need a 64 bit operating system, and the problem there is that I do not believe any screen readers are available for this as yet.

What would be the best combination for a real good desktop? Mother board, ram, HD, sound card, video card, and what ever needed to make a real good one. For example, is it possible to have 16 GB of ram on a desktop? Or what is the highest processor I can get and how many of them can I have on a mother board? if the answer is yes, would I be able to benefit from it by using Jaws, Sonar with ct on that system? As far as I know, windows XP does not recognize more then 3 GB of ram. If that is the case, Will I have to use Vista? Thanks allot, Caglar
