Default Description
[DMA 3] Sets the DMA channel for the FIR mode of operation.
[Enabled] Selects configuration method for parallel port. The selection
Auto makes the BIOS or operating system choose the configura-
tion. The Disabled selection means that the parallel port is not
configured for use. The Enabled selection provides for configur-
tion setup by the user. When Enabled is selected the choices for
setting Base I/O address and Interrupt level are displayed.
[Bi-directional] Selects the mode for the parallel port. Bi-directional (Full
Duplex) is two way transfer of information between your note
book and a connected parallel device. Example: if your notebook
is connected to a parallel printer, it can transfer data and control
information to the printer and receive status and error inform
tion from the printer. Output only (Half Duplex) is information
transfer in one direction only, it can transfer data and control
information to the printer but CANNOT receive status and error
information from the printer. ECP allows communication with
ECP class devices.
