KP915GV Product Manual 1.4 Configuration The majority of the configuration of the motherboard is done through the Setup utility built into the BIOS – discussed later in this document. There are, however, a number of jumpers that control the operation of the motherboard as described below. Some jumpers are not fitted to certain products. Figure 3.
KP915GV Product Manual Recover Mode (No jumper) With no jumper installed on pins 1, 3, and 5 recovery mode is entered. The motherboard does not boot and waits until a valid recovery diskette is detected and then copies new BIOS into the ROM. The motherboard must be powered down and then re-powered with the jumper in the normal position before normal operation can resume. CPLD Write Enabled (Jumper between pins 2 & 4) In this position the contents of the CPLD can be reprogrammed.
KP915GV Product Manual Tamper Switch To make use of the tamper detection logic of the motherboard, connect a momentary switch between pins 18 and 20. The switch should be open when the chassis is closed. 1.4.5 Alternate Power LED The power LED function on the front panel connector is duplicated on the Alternate Power LED connector for use with LEDs cabled to a 3-pin connector. Do not use both the primary (front panel) and alternate connectors simultaneously. 1.5 Installation of CPU 1.5.
KP915GV Product Manual 3. Use thumb & forefinger to hold the hook of the load lever and pull the lever sideways to unlock it. Correct Wrong Warning: DO NOT use finger to lift the locking lever, as injury could occur to the finger and the SKT could be damaged. 4. 5. 18 Lift up the lever. Use thumb to open the load plate. Be careful not to touch the contacts.

Lower the lever and lock it to the load plate, then the CPU is locked in place. CAUTION Excessive temperatures will severely damage the CPU and system. Therefore, you should install CPU cooling fan and make sure that the cooling fan works normally at all times in order to prevent overheating and damaging to the CPU. Please refer to your CPU fan user guide to install it properly.

CAUTION Be sure to unplug the AC power supply before adding or removing expansion cards or other system peripherals, especially the memory devices, otherwise the motherboard or the system memory might be seriously damaged.
KP915GV Product Manual 1.5.3 Power Supply In order to avoid damaging any devices, make sure that they have been installed properly prior to connecting the power supply. It is recommended that the board be used with a power supply that supports a minimum current load of 0.3A or less on the 5V supply rail and 2A or less on the 3.3V supply rail. This board with CPU and memory may draw as little as 400mA of 5V and 2A of 3.3V during start-up (increases depend on installed devices).

KP915GV Product Manual A.7 BIOS Organization The BIOS ROM is a 4or 8Mbit device containing eight or sixteen symmetrical 64KB blocks. The next figure shows how the ROM stores code and control information. The addresses shown refer to the ROM image at the top of the 4GB-address space. Note that the system BIOS segment is compressed in this image. When the BIOS runs, the code is uncompressed in real-time and the resulting code and data image is found at physical address 0E0000h through 0FFFFFh. Figure 11.
