I was having a really hard time getting the drivers for my Netgear WPN311 wireless ethernet card and my sound card to work with the 64-bt vista beta. Then I stumbled across this thread in a forum: http://www.planetamd64.com/index.php?showtopic=22966&hl=problems+with (sry, the address wouldn't turn into a link so just copy and paste it). Turns out my drivers were working just fine, but Vista wasn't letting them do their things because they weren't digitally signed. Right now I am hitting F8 every time windows boots and disabling the need for digitally signed drivers. Tomorrow I'm going to try to make this permanent by using a windows installation CD to access the recovery console and enter "bcdedit.exe -set nointegritychecks ON." I got this all from that link I posted, and it worked like magic. I am hoping this helps people who have been fighting with Vista to get their drivers to work.
