Troubleshooting
Problem: I am installing a parallel port(s) and my system freezes up
when Windows tries to install the driver for my printer port.
Solution: Enter your system bios, set the onboard parallel port I/O
address to 278h, save and exit. In certain systems, the address 278h
is reserved for ISA boards. So when the PCI parallel port tries to
capture this address, your system gets confused and freezes up.
Problem: I am installing serial port(s) and these ports show up
without COM port assignment or they show up as COM5 and COM6
instead of conventional COM3 and COM4.
Solution: Enter your system bios, under Peripherals Configuration,
set the first onboard serial port to 03F8, IRQ 4 instead of AUTO. Set
the second onboard serial port to 02F8, IRQ3 instead of AUTO, if
applicable. Also, under PnP or PCI Configuration, turn Off or
disable PnP OS.
Problem: I have an Intel Celeron system, and when I install a serial
port, it gets assigned to COM5 or above. My serial device only works
from COM1 to COM4.
Solution: Please visit our web site at WWW.SIIG.COM, go to
Driver Update page, and download an appropriate driver for your
Intel Celeron system.
