PAE eq Page Address Extensions. It allows for 36-bit addressing, which thus lets a 32-bit computer get past the 4Gb addressing limit. They have been around on Intel archictecture for ages in some form or other. I first read about them in DDJ. A search on their website turns up http://x86.ddj.com/articles/2mpages/2mpages.htm It's also the thing that Linus Torvalds blasted a while back. http://www.theinquirer.net/?article=7966 Microsoft seem to be fairly gung-ho about it, searching on Goggle for "PAE Intel Page Address Extensions" brings up lots of links into their site.
