I finally got a chance to reboot the machine and fiddle with the BIOS parameters, found one that mentioned a 'hole', and disabled it. The box saw the memory and is running much better. (The extra 16Mb definately makes a difference as this is a file server =). Btw, the reason I responded: please add this to the FAQ. I doubt it's _frequently_ asked, but it is a very simple fix. --Jason
