Software & Applications:

The support software CD-ROM is included in the mainboard package and contains all the drivers and utility programs needed to properly run the products. Below is a brief description of each software program, and the location for its mainboard version. More information on some programs is available in a README file located in the same directory as the software. If the operating system used in the system is Windows 98, all drivers and utilities will automatically install. See the Auto-Installing under Windows 98 section.

Installing Support Software:

The software on the support CD-ROM is for Windows 95/NT/2000 and Windows 98. The installation procedure differs depending on which Operating System is used, but the automatic installation is for Win98 only.

Installing Under Windows 95/NT/2000:

To install support software for Windows 95/NT/2000, follow these general procedures:

  1. Insert the support CD-ROM disc in the CD-ROM drive. (The system might get an error message from the PnP function. Don't care the message. You don't really need that file to install the drivers).
  2. Use My Computer or Windows Explorer to look at the directory structure. Open the command in the right-button menu. Double-clicking on the drive icon will result in an error message because the disc's AutoRun feature doesn't work in Windows 95/NT/2000.
  3. Execute the EXE file name given in the description below.

Note: The correct path name for each software driver is provided, where D: identifies the CD-ROM drive letter – modify if necessary.

Bus Master IDE Driver:

The IDE Bus Master Drivers allows the system to properly manage the IDE channels on the mainboard. Only need to install an IDE driver if running Windows 95. Use the default Windows driver on the Windows CD-ROM disc.

Display Drivers and Software:

The PC-cillin software program provides anti-virus protection for the system. Find this program here:

  • D:\PC-CILLIN\

Installing Under Windows 98:

The support software CD-ROM disc loads automatically under Windows 98. When the CD-ROM disc is inserted, the AutoRun feature will automatically bring up the install screen. The screen has three buttons: on it, Setup, Browse CD, and Exit. See the following screen illustration. When the Setup button is clicked, the software installation program will run, and the kind of installation can be selected. This is explained later in this section. The Browse CD button is the standard Windows command that allows examining the contents of the disc using the Windows 98 file browsing interface. The Exit button closes the Auto Setup window. To run the program again, reinsert the CD-ROM disc or click on AutoRun in the context sensitive menu for the CD-ROM drive icon in a file browser window.

Installing Software with Auto Setup:

To install support software for the system board, follow this procedure:

  1. Click on the Setup button. The install program will load and display the following screen. Click the Next button.
  2. Select the items that are wanted to set up by clicking on it (the default options are recommended). Click the Next button to proceed.
  3. The support software will automatically install. Once any of the installation procedures start, software is automatically installed in sequence. Follow the onscreen instructions, confirm commands, and allow the computer to restart as few times as is needed to complete installing whatever software is selected. When the process is finished, all the support software will be installed and working. There are some utilities that may need to be manually installed if needed, check the above section.
