It can support a wide range of processors, including all Intel CPUs (P54C) and Intel CPUs with MMX (P55C), as well as all AMD-K5 and Cyrix 6x86/6x86L CPUs. It also takes into account, as much as possible, all future CPUs. This series uses SOFT MENUTM technology, which means that all the parameters can be configured without using DIP switches or jumpers. The configuration is entirely achieved through a "Soft Switch" that allows the user to set CPU speed and operating voltage with ease. The IT5 series uses Intel 430VX and 430HX series chipsets, and has 256K or 512K Level-2 Pipeline Burst SRAM on board. It also provides an extension slot allowing the user to upgrade Pipeline Burst SRAM to 512K. Two 168-pin DIMM slots and four 72-pin SIMM slots meet the requirements for all memory configurations required by high level computing. The 168-pin DIMM slots support traditional Fast Page and EDO DRAM as a memory standard for next generation 64-bit systems. The two 168-pin DIMM slots have been reserved to meet requirements for both present and future upgrades. This series also provides two Universal Serial Bus (USB) ports and meets the Concurrent PCI Rev. 2.1 standard. It also supports IDE interface for Fast HDD (Mode 0~4), as well as IDE Bus Master. These features also meet present and future interface standards and needs. System BIOS features include Plug-and-Play (PnP), Advanced Power Management (APM), the newest Desktop Management Interface (DMI), as well as IT5's unique CPU operating frequency and voltage setup feature in order to meet modern computing demands. 1-2 Chapter 1 (1) IT5V l Specifications: 1.

This chapter will introduce step by step all the standard equipment and will also present, as completely as possible future upgrade capabilities. This mainboard is able to support all Intel Pentium including P55C with MMX, Cyrix 6x86, 6x86L and AMD-K5 processors now on the market. (For details, see specifications in Chapter 1.) However, we cannot guarantee that the description given in this manual on the circuitry of your mainboard will work for processors not listed in Chapter 1. For example, the operating voltage of Cyrix' next generation s CPUs is unknown at the present time. Thus we were not able to include these specifications in your motherboard. We will supply further information about CPU support when new CPUs arrive on the market. This chapter is organized according the following features: OE Standard external connectors · Jumpers and switches Z Installing the CPU--steps for installing Intel, Cyrix and AMD processors. · Installing cache memory--If you don' want to upgrade the cache t memory you can skip this chapter. · Installing the system memory. NNNN Before proceeding with the installation Before installing the mainboard please be sure to turn off or disconnect the power supply unit. Before making any modifications to the hardware configuration of the mainboard, the power supply to any areas of the mainboard you plan to modify should be turned off to avoid unnecessary damage to the hardware. 2-2 Chapter 2 & User friendly instructions Our objective is to enable the novice computer user to perform the installation by themselves. We have attempted to write this document in a very clear, concise and descriptive manner to help overcome any obstacles you may face during installation. Please read our instructions carefully and follow them carefully step-by-step. Installing the Mainboard 2-3 (1) Standard External Connectors Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are usually connected one-by-one to connectors located on the mainboard. You need to carefully pay attention to any connection orientation the cables may have and, if any, notice the position of the first pin of the connector. In the explanations that follow, we will describe the signifigance of the first pin. PN1 - Keylock connector Please pay attention to pin position and orientation This connector has a specific orientation. Connect the five-thread keylock connector cable to the PN1 connector pins on the mainboard. Pin number 1 2 3 4 5 Name or significance of signal +5VDC No connection Ground Keyboard inhibit Signal Ground 2-4 Computer Knowledge Chapter 2 The "keylock switch" is used to lock the computer' s keyboard. This disables the keyboard so that unauthorized persons cannot use it. When this function is in use, you will need to use the unlock key to activate the keyboard. PN1 - IDE LED connector This connector has a specific orientation. Connect the two-thread IDE LED connector cable attached to the case to the IDE LED connector on the mainboard. Pin number 7 8 Name or significance of signal LED' Cathode s LED' Anode s PN1 - Standby connector There is no specific orientation. Most of the present AT cases do not support this feature so most of you can ignore this instruction. If your case has a cable for the Standby feature, you should connect this cable to the connector on the Mainboard. Pin number 10 11 Name or significance of signal Standby power supply<+5VSB> Control signal of computer switch of the case Computer knowledge The "standby connector," unlike the traditional mechanical switch, is an electronic way to turn the computer' power s off. To use this feature, the power supply system must permit a shutdown power supply (+5VSB), support th ...
