Installation Section 3-3 System Memory Configuration Memory Layout
The EP-3VCA supports (3) PC133 168-pin DIMMs (Dual In-line Memory Module). The DIMMs is only 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 for using SDRAM.

Installation Section 3-5 External Modem Ring-in Power ON and Keyboard Power ON Functions (KBPO)
On the basis of bounded functions in I/O chipset, the two serial ports are able to support the External Modem Ring-in Power ON function. Once users connect the external modem to COM1 or COM2, the EP-3VCA mainboard allows users to turn on their system through the remote and host's dial-up control. Exclusive Keyboard Power ON Function To innovate a unique feature to benefit users, we devoted the easiest and most convenient way to turn on your system based on the the ATX power supply. How to work with it Step 1: Please check JP4 at the position 2-3 after you finished the system installation.
JP4 Keyboard Power-ON Function Selection 1-2 : Disabled(default) 2-3 : Enabled
Step 2: You can enjoy the Keyboard Power ON function (KBPO) by pressing any key and BUTTON only to turn on your system. Your system will be turned on automatically, after releasing the keys. To power off you system, you can use the Soft-OFF function under Windows 95/98. Notes: Intel ATX version 2.0 specification has recommended you use the power supply with 0.72A(720mA) in 5.0VSB. With our EP-3VCA mainboard, the 5.0VSB standby power only has to be > = 0.2A (200mA) then you can enjoy this unique benefit. However, the ATX power supply which is < 0. 2 (200mA) is still applicable to your system by placed JP4 at the position 1-2 to disable this feature.

Section 4 AWARD BIOS SETUP

BIOS Instructions

Awards 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
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.

LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD. During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD. The maximum HDD size supported by LBA mode is 8.4 GigaBytes which is obtained by the following formula: no. Cylinder x no. Head x no. Sector x bytes per sector (1024) ( 255) ( 63) ( 512) 8.4 GigaBytes
LARGE mode: Extended HDD access mode supported by Award Software. Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode. CYLS HEADS SECTOR MODE NORMAL LARGE
BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse transformation process will be made inside INT 12h in order to access the right HDD address! Maximum HDD size: no. Cylinder x no. Head x no. Sector x bytes per sector (1024) ( 32) ( 63) ( 512) 1 GigaByte

Page 4-24

Note: To support LBA or LARGE mode of HDDs, there must be some software involved. All the software is located in the Award HDD Service Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected if you are running under an Operating System which replaces the whole INT 13h.
UNIX operating systems do not support either LBA or LARGE and must utilize the Standard mode. UNIX can support drives larger than 528MB.
4-11 Save & Exit Setup
The SAVE & EXIT SETUP option will bring you back to the boot up procedure with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The EXIT WITHOUT SAVING option will bring you back to normal boot up procedure without saving any data into CMOS RAM. All old data in the CMOS will not be destroyed.
