Serial/Parallel Port Configurations Submenu of the Advanced Menu
The Serial/Parallel Port Configurations submenu allows
you to set the I/O addresses and interrupt levels for the
serial, infrared and parallel ports of your notebook.
Figure 4. Serial/Parallel Port Configurations Submenu
CAUTION
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.
POINTS
• 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 assistance.
• The BIOS will warn you of a resource conflict by plac-
ing a yellow asterisk next to each device that is in
conflict.
• All I/O addresses in Table 4 are in hexadecimal.
