If you receive an error message or the panel is blank, go to the section of this manual “Does Not Install.”

Step 4: Does Not Install

The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ resources. The modem needs one IRQ and one COM Port in order to function. Computers are usually equipped with a sound card, CD-ROM drive, Hard-drive, floppy drive, video card, two COM ports, one LPT port, keyboard, and a mouse. Each of these devices require at least one IRQ (interrupt) in order to function.

This section deals with the process of freeing IRQs and configuring P-N-P (Plug-N- Play) This requires that you know how to enter your computer system’s BIOS Setup Routine—read your computer user’s manual for information on how to enter into and use the BIOS setup.

Once inside the BIOS Setup, find the Plug-N-Play configuration and check the se- lection for “Operating System.” This can be found within the “Advanced”, “PNP/ PCI Configuration”, or “Plug and Play Configuration” section depending on the BIOS Manufacturer. If you have an Operating System selection, set it to “Plug-N- Play”, or if you have “Plug N Play” settings, set them to “on.” Next, from the infor- mation you noted in Step 2, find the interrupt selection for the IRQ your modem is using (some BIOS don’t allow individual selection of interrupts to ISA, Plug-N-Play, or PCI). Set this interrupt to Plug-N-Play. This can be called ICU (ISA Configura- tion Utility), ICU/PCI, ISA, or PNP depending on your BIOS version and manu- facturer. Do not set this interrupt to “PCI” only or to “Legacy ISA”.

If you do not have any free interrupts available, you will have to disable a COM port currently in use. See the section of this manual titled “Do This First”.

Uninstalling the Modem

If you are uninstalling the modem in Windows in order to upgrade software or rein- stall the modem as part of a troubleshooting process, it is important to follow these directions carefully. Following these instructions out of sequence can cause your sys- tem to cease responding to the mouse, the keyboard, or both.
