I'm trying to install SBS 2008 under Parallels Desktop 5 build 5.0.9220 but cannot get past the initial setup because the guest OS cannot find the ethernet controller. Parallels tool does not install, probably because the system is still awaiting configuration. Is there any way to install the necessary drivers? I found this article but it's for Desktop 4 and I'm not sure it will work with version 5. http://kb.parallels.com/en/5808
