Just a quick stupid question, but under device manager Windows XP calls my computer an ACPI Uniprocessor PC. Does anyone know what this means. I have a non-proprietary system, in other words I built it myself!

The ACPI ... it think means Adanced Pehipheral Interupt Control, basically it's a setting in your BIOS which enables interupts higher than 15. These virtual interupts are to prevent as many devices having to share.
The uniprocessor just means you have a single CPU.
If you look on your processor tab our CPU should be detected correctly (unless at you o/c settings windows doesn't recognise a speed/type match) Mine says XP2800+
ACPI stands for Advanced Configuration and Power Interface, not "Advanced Peripheral Interrupt Control", which doesn't even make the acronym ACPI does it? It makes APIC which is something completely different. And it stands for Advanced Programmable Interrupt Controller.
ACPI is a good thing to have your PC installed as. It gives you much more control over power management options plus more.
Uni- means one so effectively, it means "one processor." "Processor" basically refers to a socket or slot in which a device sits. So, uniprocessor means one socket or slot.
Multi- means more than one so effectively, it means "more than one processor."
You have one processor with two cores. In some cases, that could be labeled as "multiprocessor" but because of where you are seeing this ("computer type"), it is refering more to physical slots/sockets more than anything else.
Uniprocessor = 1 package (socket/slot), infinite cores (physical/virtual)
Multiprocessor = 2+ packages, infinite cores on each
It more or less controls how Windows addresses the socket(s)/slot(s) and does not deal with actual calculations.
