Description
[400 - 43F]
Allows user to set the infrared port base I/O address when
the Fast Infrared (FIR) port is Enabled.
(Note that if there is a conflict between the port interrupts
or addresses, asterisks will appear adjacent to the affected
port names to alert you to the fact. In that case, make a
different selection.)
[DMA 3]
Select the direct memory access channel for fast infrared
(FIR).
[Enabled]
Configures the parallel port using either no configuration
(Disabled), a user defined configuration (Enabled), or by
allowing the BIOS or OS to choose the configuration
(Auto).
[Bi-directional]
When the parallel port is enabled this option is available
allowing the user to set the mode for the parallel port. Bi-
directional allows two-way transfer of information
between your notebook and a connected parallel device.
Output Only (Half Duplex) allows information to be trans-
ferred in only one direction, from your notebook to the
printer or similar device. ECP Mode allows communication
with the ECP class of parallel I/O devices. Check your
device documentation for the proper setting.
[378 - 37F]
Allows user to set the parallel port base I/O address when
the parallel port is Enabled.
[IRQ 7]
Allows user to set the parallel port interrupt when the par-
allel port is Enabled.
