Operating System: Windows 98SE (Note: might work with other versions of this os.)
Both modems and the driver will only work on most brand computers since all computers are not the same. If it is not working on your computer, then it is not compatible.
Here are the instructions - Unzip the files and it will automatically place it in "C \Windows\Temp" folder. Next, go to the "Control Panel" and click on the "Modem" icon. Place a check mark in the box where it says "Don't Detect Modem" and click "Next". Under the listing, click on "Have Disk" then direct it to "C \Windows\Temp and click on "ok". It will automatically install it. Next reboot your computer and you're ready to connect on-line.
