Introduction EP-68LXR Overview Pentium II The Pentium® II Processor is the follow-on to the Pentium® Processor. The Pentium® II Processor, like the Pentium® Pro processor, implements a Dynamic Execution micro-architecture -- a unique combination of multiple branch prediction, data flow analysis, and speculative execution. This enables the Pentium® II Processor to deliver higher performance than the Pentium® processor, while maintaining binary compatibility with all previous Intel architecture processors.
EP-68LXR Introduction processor. This is the model used in past packaging technologies like PGA, TCP, PQFP, DIP, etc. S.E.C. Cartridge Terminology • Pentium® II Processor The new enclosed card packaging technology is called a “Single Edge Contact cartridge.” This is similar to previous names for packaging technology such as PGA or TCP.
Introduction EP-68LXR Accelerated Graphics Port (AGP or A.G.P.) Typically, 3D graphics rendering requires a tremendous amount of memory, and demands ever increasing throughput speed as well. As 3D products for the personal computer become more and more popular, these demands will only increase. This will cause a rise in costs for both end users and manufacturers. Lowering these costs as well as improving performance is the primary motivation behind AGP.
EP-68LXR Introduction Power-On/Off (Remote) The EP-68LXR 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-68LXR has been designed with “Soft Off" functions.

Configure DIP Switch and Jumper to match your hardware Install memory chips Install Pentium II Processor Device Connectors Section 3-1 Configure DIP Switch EPoX designs all motherboards with a DIP Switch to make your install fast and easy.
EP-68LXR Installation Section 3-2 System Memory Configuration Memory Layout The EP-68LXR supports (2) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). • DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or 120MHz (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.

Installation EP-68LXR Section 3-3 Installing a Pentium II Processor The EP-68LXR uses the Single Edge Contact (SEC) slot for a Pentium II processor packaged in an SEC cartridge. The SEC slot is not compatible with other nonPentium II processors. Please have ready the following list of components so that we may install the processor onto the motherboard. 1. 2. 3.
EP-68LXR Installation bottom make sure you press firmly on SEC cartridge to firmly secure into the Slot 1 Socket. Now we need to secure the heatsink with the top half of the support (figure 11). Take the top piece of the support and slide it into the bottom fin (figure 11) on the heatsink and then push forward until it clips into the bottom base (figure 9) that is already there (figure 11). Figure 9 Figure 9 shows the layout of Slot 1 and the holes for mounting the Heatsink base piece (figure 8).

EP-68LXR BIOS Section 4 AWARD BIOS SETUP BIOS Instructions 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-68LXR 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.
EP-68LXR BIOS NOTE: The “Halt On:” field is used to determine when to halt the system by the BIOS if an error occurs. NOTE: Floppy 3 Mode support is a mode used to support a special 3.5” drive used in Japan. This is a 3.5” disk that stores only 1.2 MB, the default setting for this is disabled. 4-2 BIOS Features Setup Selecting the “BIOS FEATURES SETUP” option in the CMOS SETUP UTILITY menu allows users to change system related parameters in the displayed menu.
BIOS EP-68LXR Enabled: Activates automatically when the system boots up causing a warning message to appear when anything attempts to access the boot sector.

EP-68LXR BIOS Figure 8: IDE HDD Auto Detection NOTE: HDD Modes The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL mode Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing. The maximum number of cylinders, head & sectors for NORMAL mode are. 1024, 16 & 63 no. Cylinder x no. Head x no. Sector x no.
BIOS EP-68LXR 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.
EP-68LXR BIOS UNIX operating systems do not support either LBA or LARGE and must utilize the Standard mode. UNIX can support drives larger than 528MB. 4-10 HDD Low Level Format Interleave: Select the interleave number of the hard disk drive you wish to perform a low level format on. You may select from 1 to 8. Check the documentation that came with the drive for the correct interleave number, or select 0 for automatic detection.
EP-68LXR DMI Access Section 5 DMI ACCESS DMI Access DMI, or desktop Management Interface, is a feature that is able to auto-detect and record information about your computer system. This information is used by computing professionals to accurately determine your system configuration and to diagnose and resolve problems. The computer’s BIOS will detect and record as much information as it is able to, and will store that information in a special location in the BIOS.
