Serial/Parallel Port Configuration Submenu of the Advanced Menu
The Serial/Parallel Port Configuration submenu lets you 
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
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 address 
assigned, your notebook will not function 
normally. Keep a record of original settings 
before making any changes if restoration is 
required. See your hardware and software 
documentation as well as the setup utility 
to determine settings and limitations.
■
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.
■
If your notebook emits a series of beeps 
that sounds like a code and the display is 
blank, refer to the Troubleshooting Sec-
tion in the system User’s Guide. The 
Troubleshooting Section includes a list of 
error messages and their meanings.
■
All I/O addresses in Table 5 are in hexa-
decimal.
