CHAPTER 2 INSTALLATION

2-1 INSTALLATION PROCEDURE

Before installing the computer, please prepare all components such as CPU, DRAM;
peripherals such as hard disk drive, keyboard, CD-ROM and accessories such as
cables. Then, install the system as following:
 Plug CPU/ heat sink (refer to Pentium
installation guide, Appendix A), and DRAM modules on the
mainboard.
 Set DIP switch & jumpers based on your configuration.
 Plug add-on cards into PCI/ISA slots, if needed.
 Connect cables to peripheral devices, especially for power supply.
 Make sure all components and devices are well connected, turn on the
power and setup System BIOS based on your configuration.
Install peripheral devices, add-on card drivers and test them.
 If all of above procedures are running successfully, turn the power off
and screw the chassis cover to the chassis, and then connect external
devices which are cabled to the system.
Note: PCI slot 2 share the same interrupt number (INT#) with the
onboard sound. For this sake, please plug the card which is able to
share an INT# or needn't use an INT# in PCI slot 2.

2-2 CPU INSTALLATION

The mainboard has built-in VID (Voltage Identify) function to automatically detect
CPU voltages. Thus you do not have to set the CPU voltage setting.
