Do not reassign an interrupt that is already in use by an ISA card to the PCI
bus. Since each BIOS manufacturer has a different way of handling these
configurations, you may have to use trial-and-error to get your modem prop-
erly configured. Be sure to Save the settings before exiting the BIOS Setup.
• You are now ready to install the modem. Proceed to the Installing the Mo-
dem section.

• If you are replacing the current modem in your computer system with this
new modem, be sure to remove all other modem drivers from your operating
system. Go to: Start-Settings-Control Panel and double-click on the Mo-
dems icon. Highlight the modem you wish to remove and click the Remove
button. Shutdown the computer, power-down, and physically remove the
modem from your system. Do not install your new modem at this time. Fol-
low the procedures below to help insure a trouble-free installation. Note:
once you remove the old modem and its drivers from your system, you will
need the old modem driver diskette if you wish to reinstall it at a later date.
• Determine that your operating system has the latest upgrade available. “Ser-
vice Pack 3” (or greater) should be installed. Go to Start- Settings-Admin-
istrative Tools-Windows NT Diagnostics. Select the Version folder. “Ser-
vice Pack 3” (or greater) should be stated. If you do not have the latest service
pack upgrade installed, it must be obtained from Microsoft. The latest up-
grade can be downloaded from the Microsoft ftp site.
• (Note: If you are not familiar with changing the settings within your system
BIOS setup, you should skip the following system preinstallation procedure
and go to the Installing the Modem section. Refer back to this area only if
you have a problem with installing the modem.)
Check your system BIOS IRQ assignments and make sure that at least
two interrupts (especially any unused interrupts) have been assigned to the
PCI bus. Go to your system BIOS Setup routine and find the Plug-N-Play
settings. These settings can be found within the Advanced, PNP/PCI Con-
figuration, or Plug and Play Configuration sections depending on the BIOS
Manufacturer. Next, verify that at least two IRQs have been set so that the
PCI bus has access to them (some BIOS don’t allow individual selection of
interrupts to ISA, Plug-N-Play, or PCI). These settings can be called ICU,
ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer.
Do not set all the interrupts to “ISA” only or to “Legacy ISA”. Pay attention
to the IRQ usage of the other peripherals in your system. Do not reassign an
interrupt that is already in use by an ISA card to the PCI bus.
