mentioned key combinations work or no message is displayed while the computer is
starting up, please refer to your computer system manual for instructions on how to
enter the BIOS setup.
Once inside the BIOS setup, find the menu for integrated peripherals, locate the
COM port settings, then disable COM2 (Sometimes known as “Comport B” or
“Serial B”.) If unsure, please consult your computer’s user manual. Be sure to save
these settings before exiting the BIOS Setup. The computer will then restart. Set your
modem’s jumpers to COM 2-IRQ 3. (See the “Installing the Modem” section of this
manual for jumper setting diagrams.)
Next find and disable the Plug-N-Play settings in the BIOS. These settings can be
found within an “Advanced”, “PNP/PCI Configuration”, or “Plug and Play Con-
figuration” section (depending on the BIOS Manufacturer.)
Verify that one free IRQ has been set so that the ISA bus has access to it. (Some BIOS
don’t allow individual selection of interrupts to ISA, Plug-N-Play, or PCI.) These
settings can be called ICU, ICU/PCI, or PNP depending on your BIOS version and
manufacturer. Do not set this interrupt to “PCI only.” Pay attention to the IRQ
usage of the other peripherals in your system. Do not reassign an interrupt that is
already in use by another device. Be sure to Save these settings before exiting the BIOS
Setup.
You may also need to disable the COM Port from the device manager. On the desk-
top, right-click the My Computer icon and choose Properties. Select the Device
Manager tab. Double-click the Ports (COM & LPT) icon to expand the list of ports
and highlight Communication Port (COM2). Now click on the Properties button.
Click to select Disable in this hardware profile (Windows 95 OEM SR2 only) or
click to deselect Original Configuration (current) (Windows 95 or Windows 95A
only.) Exit Windows 95 and restart your system. Note: If COM 3 and or COM 4 are
present and you have nothing installed on these ports, delete them first before delet-
ing COM 2.
Proceed to the “Installing the Modem” section of this manual.
Jumper Settings
This modem has two sets of jumper blocks used for manual COM Port and IRQ
(interrupt) selection. Figure 6 shows the default jumper setting for JP1 and JP2 as
shipped from the factory. This setting is for “Plug-N-Play” and will auto-configure in
computers with operating systems that support this feature, like Windows 95 and
98. When performing a non Plug-N-Play installation, the best choice for these set-
tings is COM 2 IRQ 3.
