Parallel port Controls whether the computer's parallel port acts as an advanced
technology (AT)-compatible unidirectional, a PS/2-compatible
bidirectional, an Enhanced Parallel Port (EPP)-compatible, or an
Extended Capabilities Port (ECP)-compatible port. Dell recommends that
you retain Auto (the default) to allow the operating system or the BIOS
to configure the port automatically. Other options are Disabled, which
disables the parallel port, and Enabled.
To enter a custom configuration, set Parallel Port to Enabled and then
configure Mode, Base I/O Address, and DMA channel.
