The Serial/Parallel Port Configuration submenu

provides the ability to set the I/O addresses and

interrupt levels for the serial, infrared, and parallel

ports of your notebook.

Figure 5. Serial/Parallel Port Configuration Submenu
■To prevent IRQ and address conflicts,
avoid changing the default settings. If
you must change the settings, you can
call 1-800-8Fujitsu for technical assis-
tance.
■The BIOS will warn you of resource con-
flicts by placing a yellow asterisk next to
each device that is in conflict.
■All I/O addresses in Table 5 are in hexa-
decimal.
I/O addresses, DMA channels, and
Interrupt levels can be entered in various
ways, including via the BIOS setup utility,
the control software for the I/O device, or
the hardware. If any two ports or devices,
serial or parallel, have the same I/O
address assigned your notebook will not
function normally. Please keep a record of
original settings before making any
changes in the event that a restoration is
required. See your hardware and software
documentation as well as the setup utility
to determine settings, limitations, etc.
