Plug and Play
The system comes with a Plug and Play BIOS which supports Plug and Play technology.
Plug and Play eliminates complicated setup procedures for installing Plug and Play
expansion boards. With Plug and Play, adding a Plug and Play expansion board is done by
turning off the system, installing the board, and turning on the system. There are no jumpers
to set and no system resource conflicts to resolve. Plug and Play automatically configures
the board.
