Drivers Installation SY-5EHM/5EH5

Chapter 4

DRIVERS INSTALLATION

Your SY-5EHM/5EH5 Super 7™ Mainboard comes with a CD-ROM labeled "SOYO CD." The SOYO CD contains the user's manual file for your new Mainboard, the drivers software available for installation, and a database in HTML format with information on SOYO Mainboards and other products.

Step 1. Insert the SOYO CD into the CD-ROM drive

The SOYO CD will auto-run, and the SOYO CD Start Up Menu will display as shown below.

(SOYO CD Start Up Program Menu)

The SOYO CD Start Up Program automatically detects which SOYO Mainboard you own and displays the corresponding model name.

Drivers Installation SY-5EHM/5EH5

Step 2. Iinstallation procedure for Windows 95/98

The following describes the best way of installing Windows 95 or Windows 98 on your 5EHM/5EH5 mainboard:

Ø The following BIOS default settings should not be changed:

1. The ‘USB Controller’ item under ‘Chipset features’ is set to enabled.

2. The ‘USB Assigned IRQ’ item under ‘PnP/PCI Configuration is set to enabled. You MUST have these two items enabled for Windows 95/98 to run properly on your

system.

Ø Install Windows 95/98 Ø After installation of windows, you will need to install the ETEQ drivers. Follow the

instruction below.

Click the Install Drivers button to display the list of drivers that can be installed on your mainboard. The start-up program displays the drivers available for the 5EHM/5EH5 and the Windows version you use. For Windows 95 four drivers will be listed (see ‘Driver Installation Menu’ below), for Windows 98 three drivers will be listed (the ACPI drivers will be left out). We recommend you to install all drivers, and to do so in the right sequence (top to bottom).

If you want to see all the drivers available on the SOYO –CD, click the Display all drivers on the SOYO CD button. Do NOT install drivers that are not suitable for you board, otherwise your system may crash.

(Driver Installation Menu)

Drivers Installation SY-5EHM/5EH5

Select which driver you want to install and click OK, or click Cancel to return to the main menu. When the installation program of a driver starts running the SOYO-CD will exit. After finishing the installation, restart the SOYO-CD and install the next driver.

Note: Once you have selected a driver, the system will automatically exit the SOYO CD to begin the driver installation program. When the installation is complete, most drivers require to restart your system before they can become active.
