Identify which CD pertains

[Ken]

I had a small business and owned about 6 original Physical
versions of Office 2000. I want to do a Service Pack
update and it will require that I load the original CD. Is
there any way I can tell which of these 6 CD's is the one
on my current system. I have all my Serial numbers etc.

Thanks

For an sp update I dont think it matters
