Ben "Virtual PC Guy" Armstrong's recent post sent me back to my early days at Microsoft.  Back then (early 1990s) I was a member of the MS-DOS product support team.  His link to the Microsoft Knowledge Base article was one I remember fondly.  Many times I walked customers through these instructions over the phone.  Customers with fax machines could also call our fax-back service and request a hard copy of the article - it wasn't quite internet easy, but it was pretty close :) 

Just for fun, here's another of my old favorites (Requesting MS-DOS Version Number with DEBUG).  Give it a try the next time you are running an MS-DOS Virtual PC session.

Enjoy!
