KT-748 MAINBOARD MANUAL DOC No.: M03403 Rev. Date : A0 : 6, 2003 Part No. : 25-11663-00 Notice Handling Precautions Warning: 1. Static electricity may cause damage to the integrated circuits on the motherboard. Before handling any motherboard outside of its protective packaging, ensure that there is no static electric charge in your body. 2. There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or an equivalent type recommended by the manufacturer. 3. Discard used batteries according to the manufacturer' s instructions. 4. Never run the processor without the heatsink properly and firmly attached. PERMANENT DAMAGE WILL RESULT! Observe the following basic precautions when handling the motherboard or other computer components: n Wear a static wrist strap which fits around your wrist and is connected to a natural earth ground. n Touch a grounded or anti-static surface or a metal fixture such as a water pipe. n Avoid contacting the components on add-on cards, motherboards, and modules with the golden fingers connectors plugged into the expansion slot. It is best to handle system components by their mounting brackets. The above methods prevent static build-up and cause it to be discharged properly.

By utilizing DDR ( Double Data Rate ) transfer rate effectively reaches Front Side Bus speeds of 200/266/333/400 MHz. The board provides users with an ATA133 data transaction for hard drives and has 3 PC2100/PC2700/PC3200* DIMMs for up to 3 GB. (* Only two PC3200 SDRAMs at most are allowed on board.) The board is based around the high performance SiS 748TM as North Bridge and SiS 963/LTM (as South Bridge. Its AGP 8X functions supported AGP 3.0 interface and the most robust 3D games with software environments. The AGP slot onboard supports 0.8/1.5 volt AGP card . The board comes with a versatile range of I/O features such as 2 serial ports, 1 parallel port, 1 LAN, 2 optional IEEE 1394, 1 PS/2 mouse and keyboard connector, 6 USB ports, 1 media connector (front audio, Line-in, Line-out and Mic-in). In addition, the board is equipped with 5.1 audio channel enhanced PCI bus master IDE connectors. Ample expansion is available through 5 PCI* and 1AGP to meet the requirement for enjoying the CPU benefits in internet applicatons, video/3D graphics performance, and so forth. (* PCI1 to 4 are master; PCI5 slot is slave.) Other key features are Remote On/Off, Auto Power Failure Recovery, integrated temperature monitoring and system fan control. Included also is lst Utilities CD with enhanced drivers and a few bundled soft-ware solutions. 1-1 KT-748 Mainboard Manual Package Checklist If you discover any item below was damaged or lost, please contact your vendor. NOTE: lst Utilities CD that contains patch files, onboard video/audio chip drivers, related online help and other useful information can be found in your mainboard package.

WARNING: BIOS Guardian must be disabled before reflash BIOS. NOTE: Please read Page 3-6 for detail information. n Easy Key Instead of completing the multi-layered BIOS setup process these 3 Easy Key functions provide direct access to Sub-Menu when completing BIOS settings adjustments. Easy-Keys are as follows: Ctrl + c: To enter clock settings menu. Ctrl + p: To load Performance Default settings and restart. Ctrl + f: To load Fail-Safe Default settings and restart. 1-6 Installation Chapter 2 Procedures Installation Procedures The mainboard has several user-adjustable jumpers on the board that allow you to configure your system to suit your requirements. This chapter contains information on the various jumper settings on your mainboard. To set up your computer, you must complete the following steps: Step 1 - Set system jumpers Step 2 - Install memory modules Step 3 - Install the Central Processing Unit (CPU) Step 4 - Install expansion cards Step 5 - Connect ribbon cables, cabinet wires, and power supply Step 6 - Set up BIOS software Step 7 - Install supporting software tools WARNING: Excessive torque may damage the mainboard. When using an electric screwdriver on the mainboard, make sure that the torque is set to the allowable range of 5.0 ~ 8.0kg/cm. Mainboard components contain very delicate Integrated Circuit (IC) chips. To prevent static electricity from harming any of the sensitive components, you should follow the following precautions whenever working on the computer: 1. Unplug the computer when working on the inside. 2. Hold components by the edges and try not to touch the IC ||||chips, leads, or circuitry. 3. Wear an anti-static wrist strap which fits around the wrist. 4. Place components on a grounded anti-static pad or on the bag that came with the component whenever the components are separated from the system. 2-1 KT-748 Mainboard Manual 1). Set System Jumpers NOTE: Users are not encouraged to change the jumper/switch settings not listed in this manual. Changing the settings improperly may adversely affect system performance. Clear CMOS The CMOS RAM is powered by the onboard button cell battery. To clear the RTC data: (1) Turn off your computer; (2) open the system case, disconnect the ATX power cable; (3) place the jumper cap onto the pinpair 2-3 at least 6 seconds to enable CMOS clearance; (4) place the jumper cap onto the pinpair 1-2 to disable the effect of CMOS clearance; (5) connect the ATX power cable; close the system case; (6) turn on your computer until CMOS checksum error appears; (7) hold down the Delete key when boots; (8) enter the BIOS Setup to re-enter user preferences. 123 Disable (Default) 123 Enable (Clear CMOS) 2-2 Installation Procedures BIOS Anti-Reflash Protect The jumper helps users to prevent the 64K boot block table area in the BIOS ROM from being overwritten by mistake. 2).
