Help! i have apparently lost some system drivers on a sony laptop.using artition magic i merged two partitions into one and ended up with similar problems to this guy click here "Advanced Configuration & Power Interface (ACPI) BIOS". I clicked on that to install it and got the message, "Windows could not load the driver for this device because the computer is reporting two ACPI.SYS Bus types (Code 2)". does anyone know where i might get new drivers? sony site click here isn't much help, and i cannot seem to find what i need on driverguide either. the laptop is sony vaio model PCG-F801.
