Serial/Parallel Port Configuration Submenu of the Advanced Menu
The Serial/Parallel Port Configuration submenu
provides the ability to set the I/O addresses and inter-
rupt levels for the serial (infrared) and parallel ports of
your notebook.
Figure 5. Serial/Parallel Port Configuration Submenu
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
have the same I/O address assigned, your
notebook will not function normally.
• 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 placing a yellow asterisk
next to each device that is in conflict.
• All I/O addresses in Table 5 are in
hexadecimal.
