Introduction EP-3VCA2

EP-3VCA2 F orm-Factor

The EP-3VCA2 is designed with ATX form factor - the new industry standard of chassis. ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards. ATX defines a double height aperture to the rear of the chassis which can be used to host a wide range of onboard I/O. Only the size and position of this aperture is defined, allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem, LAN, etc.) to systems. This will help systems integrators differentiate their products in the marketplace, and better meet your needs.

 By integrating more I/O down onto the board and better positioning the hard

drive and floppy connectors material cost of cables and add-in cards is reduced.

 By reducing the number of cables and components in the system, manufactur-

ing time and inventory holding costs are reduced and reliability will increase.

 By using an optimized power supply, it's possible to reduce cooling costs and

lower acoustical noise. An ATX power supply, which has a side-mounted fan, allows direct cooling of the processor and add-in cards making a secondary fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)

The EP-3VCA2 has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button. The systems power On/Off button should be a momentary button that is normally open.

The EP-3VCA2 has been designed with Soft Off" functions. You can turn Off the system from one of two sources: The first is the front panel Power On/Off button, and the other is the "Soft Off" function (coming from the EP-3VCA2s onboard circuit controller) that can be controlled by the operating system such as Windows 95/98. System will be turn off automatically after your click the START button and resume the Shutdown selection.

Section 3-3 System Memory Configuration

Memory Layout

The EP-3VCA2 supports (3) PC133 168-pin DIMMs (Dual In-line Memory Module). The DIMMs is for SDRAM (Synchronized DRAM).

 DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or

125MHz (8ns) bus speed.

 If you use both 50ns and 60ns memory you must configure

your BIOS to read 60ns.

 When using Synchronous DRAM we recommend using the

4 clock variety over the 2 clock.

Figure 6 and Table 1 show several possible memory configurations using both SIMM and DIMM.

BIOS SETUP

Main Menu

Awards ROM BIOS provides a built-in Setup program which allows user to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added.

It is possible for the CMOS battery to fail, this will cause data loss in the CMOS only. If this does happen you will need to reconfigure your BIOS settings.

To enter the Setup Program :

Power on the computer and press the <Del> key immediately, this will bring you into the BIOS CMOS SETUP UTILITY.

Figure 1: CMOS Setup Utility

Page 4-1

BIOS EP-3VCA2

The menu displays all the major selection items. Select the item you need to reconfigure. The selection is made by moving the cursor (press any direction key ) to the item and pressing the Enter key. An on-line help message is displayed at the bottom of the screen as the cursor is moved to various items which provides a better understanding of each function. When a selection is made, the menu of the selected item will appear so that the user can modify associated configuration parameters.

4-1 Standard CMOS Setup

Choose Standard CMOS Setup in the CMOS SETUP UTILITY Menu (Figure 2). The Standard CMOS Setup allows the user to configure system settings such as the current date and time, type of hard disk drive installed, floppy drive type, and display type. Memory size is auto-detected by the BIOS and displayed for your reference. When a field is highlighted (use direction keys to move the cursor and the <Enter> key to select), the entries in the field can be changed by pressing the <PgDn> or the <PgUp> key.
