I installed Vista Beta2 today. The installation went fine and without any problems. However, when the system came up, it didn't have drivers for the network card, or the audio drivers. This is on a 1.2 Ghz system that I have been running for the past two years. I got from a friend second hand. I have no idea when he got it. And I'm pretty sure it worked fine in an earlier build of Vista, but I might be wrong.
In any case, I'll have to open up the box, check what network card it has and see if I can scrounge up drivers for this card. Its surprising to me though. I thought Microsoft was all about backwards compatibility? This install is taking 11.7 GB of space. What in the heck is in that 11.7 GB? Hey I understand if that cool new interface won't work with the old crappy video card, but the NETWORK CARD!
Its a good way to protect your machine from viruses, trojans and spyware though. Just don't connect to the network! :)
UPDATE: its a 3com 3c905B. Can't find drivers for it online, and no point in trying XP drivers. If they would've worked, I'm sure they would've been included.
It also doesn't install in Virtual PC for me on my Powerbook G4. Sigh.
