Features EP-BX5 • EP-BX5 utilizes a Lithium battery which provides environmental protec tion and longer battery life. • Supports the Universal Serial Bus (USB) connector. The onboard PIIX4E chip provides the means for connecting PC peripherals such as; keyboards, joysticks, telephones, and modems.
Installation EP-BX5 The following must be completed before powering on your new system: 3-1. Configure Jumpers 3-2. System memory Configuration ® 3-3. Install Pentium II/III/Celeron Processor 3-4. Device Connectors 3-5. External Modem Ring-in Power ON and Keyboard Power ON Functions (KBPO) The following will describe all of the setting that you are required to set before moving on to step 3-2.

Installation EP-BX5 I I I Note: Based on the implementation of the Intel 440BX AGPset, the EP-BX5 is able to provide multiple front side bus (FSB) frequencies for Slot 1 processors and memory operations. The mainboard's FSB is easily se- lected by BIOS Setup listed above to match the FSB required by your processor.

Installation EP-BX5 The EP-BX5 supports (4) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized DRAM). • We recommend not mixing SDRAM DIMM and EDO DIMM together. • EDO DIMM can only be used with the 66MHz FSB.
Page 23
Installation EP-BX5 Figure 3 displays the notch marks and what they should look like on your DIMM memory module. DIMMs have 168-pins and two notches that will match with the onboard DIMM socket. DIMM modules are installed by placing the chip firmly into the socket at a 90 degree angle and pressing straight down (figure 4) until it fits tightly into the DIMM socket (figure 5).
Page 24
Installation EP-BX5 ® The EP-BX5 uses the Single Edge Contact (SEC) slot for a Pentium II/III processor packaged in an SEC cartridge. The SEC slot is not compatible with ® other non-Pentium II/III processors. Please have ready the following list of components so that we may install the processor onto the motherboard.

Installation EP-BX5 (This is connected to the power button on the case. Using the Soft- Off by Pwr-BTTN feature, you can choose either Instant Off (turns system off immediatly), or 4 sec delay (you need to hold the button down for 4 seconds before the system turns off). When the system is in 4 sec delay mode, there is a special feature to make the system to go into suspend mode when the button is pressed momentarily.)
Page 28
Installation EP-BX5 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 mainboard allows users to turn on their system through the remote and host's dial-up control.
Page 29
Installation EP-BX5 Notes: 1. Intel ATX version 2.0 specification has recommended you use the power supply with 0.72A(720mA) in 5.0VSB. With our mainboard, the 5.0VSB standby power only has to be > = 0.1A (100mA) then you can enjoy this unique benefit.
EP-BX5 BIOS 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.

BIOS EP-BX5 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.

EP-BX5 BIOS The “IIDE HDD auto detection” utility is a very useful tool, especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type installed in the system automatically. But now you can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP.

BIOS EP-BX5 If user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that! LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck.
Page 59
EP-BX5 BIOS 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.
