Virtual Server and Virtual PC differences - today's triva

Ben posted up an article a few days ago about the amount of Video Memory in the emulated S3 Trio graphics adapter under Virtual PC. His answer - 8MB. Obviously there are a number of differences between Virtual Server 2005 (R2) and Virtual PC 2004 in terms of emulated hardware, most of which are well documented (sound, SCSI etc). As a rule, I use Virtual Server 2005 for everything in my testing - very rare is it that I fire up Virtual PC. I've been asked in the past several times how much memory is supported by the S3 Trio adapter emulated under Virtual Server - the answer I give is 4MB (which it is). I've always assumed so far that it was the same between both environments without checking into this. As you can see, it isn't. However, in a production virtual server environment, 4MB is ample for most purposes obviously. One of those things to file for next time you're playing Virtual Trivial Persuit with your colleagues... or is that just me ;)
