I think I tried that 2008 Basilisk II build as well and it failed for some reason or other. Even went right back to the old 2000 or 2001 builds. Back in the good old days I was running 2000 and then XP. Now it's 7 and 64-bit to boot, so there's probably a few gremlins added to the mix.

As for SheepShaver it works fine for what I need in most cases. The only networking I use is the router emulation so I can get it online.
