We've found that certain IDE drivers can cause problems in Pyro. Go to your Device
Manager and open the IDE/ATAPI Controllers. If you see anything there other than Microsoft's
generic drivers (Primary, Secondary, etc..) You'll want to force your system to use
Microsofts generic drivers. Double click on each device, go to Driver | Update Driver
| Install from a list | Don't Search | choose Primary, Secondary or Standard for the
appropriate controller.
