Restart the system and go into the system board BIOS. Then go into Integrated Peripherals and
make sure the "AC97 Modem" setting is ENABLED. Save and exit from the BIOS.
Click on Start / Programs / MS-DOS Prompt to open up a DOS window. Create
a \modem folder in the root of C: by typing in these commands:
md modem [enter]
Download or copy the 98 driver (1.2MB) to the c:\modem folder and
run it to extract the files.
Then follow the screens:

Check Device Manager (right click My Computer, go to Properties, and click
on the Device Manager tab) to make sure the modem is not already present.
If it's present, it will appear as a "PCI Card" under the Other devices
entry.
To remove it, select the PCI Card entry and click on the REMOVE button.

The system will ask you to confirm the device removal; click on OK. After the
device is gone, click on the REFRESH button (see above Device Manager screenshot).

The system will detect the modem as a PCI card device; click on NEXT to continue.

Select the first option (Search for the best driver...) and click on NEXT.

Uncheck all the boxes, except for "Specify a location" and type in
c:\modem in the window below.

The system will find the AMR voice modem. Click on NEXT to continue.

After the drivers loaded, click on FINISH to continue.

Select your country. If you're using the modem at home, you can clear the
Enable PBX box; otherwise, leave it checked. Click on OK to finish the setup.
