Pull out the lever from the socket, and then raise the lever up to a 90-degree angle.
Take notice of the red circles as shown below. While inserting the CPU into the socket, you can find out there is a definite pin orientation for CPU and socket.
Make sure that the CPU is placed into the socket tightly. Then lower down the level to complete the CPU installation.

2-2 MEMORY INSTALLATION

WARNING!!!
Make sure to unplug your power supply before adding or removing memory modules or other system components. Failure to do so may cause severe damage to both your mainboard and expansion cards. Be careful when inserting or removing DIMM. Forcing a DIMM in or out of a socket improperly may damage the memory module or the socket. Some DIMMs which contain EDO or FTP DRAM are incompliant with the mainboard. The M/B supports 2.5V DDR SDRAM only.

Installing DIMM

Make sure you have the correct memory module type for your mainboard. Insert the module(s) as shown below, DIMMs have 184-pins and one notch that will be matched by the onboard DIMM socket. Memory modules are installed by inserting them straight into the slot until they click in the right place. They only fit in one direction, so do not force them in by a wrong direction.

BIOS SETUP

THE BIOS

BIOS stands for Basic Input and Output System. It is sometimes called ROM BIOS because it is stored in a Read-Only Memory(ROM) chip on the mainboard. BIOS is the first program to run when you turn on your computer. BIOS performs the following functions: 1. Initializing and testing hardware in your computer (a process called POST , for Power On Self Test). 2. Loading and running your operating system. 3. Helping your operating system and application programs to manage your PC hardware by means of a set of routines called BIOS Run-Time Service.

ATAPI (AT Attachment Packet Interface) This is the exension of the EIDE (extended IDE) that enables the interface to support CD-ROM players and tape drives. BIOS (Basic Input/Output System) BIOS is a set of assembly routine/program that resides in EPROM or Flash ROM. BIOS controls Input/output devices and other hardware devices of the mainboard. Generally, operation system and drivers will access BIOS before accessing hardware devices so as to enhance the portability of the hardware devices. Bus Master IDE (DMA mode) An IDE interface is an interface for mass storage devices, in which the controller is integrated into the disk or CD-ROM itself. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without interrupting CPU, and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need the bus master IDE driver and the bus master IDE HDD to support bus master IDE mode. CAS (Column Address Strobe) CAS is a technology of DRAM writes and reads. The number of clock cycles of the CAS signals is depending on the DRAM timing. CNR (Communication and Networking Riser) CNR interface provides a cost reducing method of implementing LAN, home networking, DSL, USB, wireless, audio and modem subsystems through a CNR card and a CNR connector. CODEC (Coder and Decoder) Normally, CODEC means a circuit that can do digital to analog conversion and vice versa. It is part of AC97 sound/modem solution. DDR (Double Data Rated) SDRAM DDR SDRAM essentially doubles the memory speed of SDRAMs without increasing the clock frequency.
DIMM (Dual In Line Memory Module) DIMM socket is built with a 168-pin assignment and supports 64-bit data. DIMM can be single or double sided. The golden finger signals on each side of the module are different, and that is why it is called Dual In Line. Almost all DIMMs are made with SDRAM now, which operate at 3.3V. Some old DIMMs are made by FPM/EDO and only operate at 5V. DMA (Direct Memory Access) Channel for communications between memory and surrounding devices. ECC (Error Checking and Correction) The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error. ECP (Enhanced Communication Port) ECP is a technology designed to improved I/O for parallel ports. EPP (Enhanced Parallel Port) EPP is a standard that supports data transfer rates of up to 500 kps for parallel printers EDO (Extended Data Output) Memory Unlike traditional FPM (Fast Page Mode) memory that tri-states the memory output data to start the pre-charge activity, EDO DRAM holds the memory data valid until the next memory access cycle, which is similar to pipeline effect in reducing one clock state. EEPROM (Electronic Erasable Programmable ROM) Both EEPROM and Flash ROM can be re-programmed by electronic signals, but the interface technology is different. Size of EEPROM is much smaller than flash ROM. BIOS is now generally stored in EEPROM or Flash ROM. EPROM (Erasable Programmable ROM) Traditional mainboard stores BIOS codes in EPROM which can only be erased by ultra-violet (UV) light. If BIOS has to be updated, you need to remove EPROM from mainboard, clear data by UV light, re-program, and then insert it back to socket.

FC-PGA (Flip Chip-Pin Grid Array) FC means Flip Chip, while FC-PGA is a new package of Intel for Pentium III CPU. It is compatible with SKT370 socket, but requires mainboard to add some signals on socket 370. Flash ROM Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit) or more. FSB (Front Side Bus) FSB is the data channel connecting the Processor to chipset, RAM, mainboard buses, AGP socket etc. Its speed is in terms of MHz and is talked to as FSB clock: FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio IEEE 1394 IEEE 1394 is a low-cost digital transfer interface with transfer rate at 100, 200 or 400 Mbps. It provides solutions of connecting digital television devices and Serial Bus Management. There are two type of IEEE 1394 data transfer: asynchronous and isochronous. Isochronous data channels provide guaranteed data transport at a pre-determined rate. This is especially important for time-critical multimedia data where just-in-time delivery eliminates the need for costly buffering. Parity Bit The parity bit mode of error detection uses 1 parity bit for each byte. Normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count 1 for each byte. Next time when memory is read with odd number of 1, the parity error is occurred and this is called single bit error detection. PC-100 DIMM SDRAM DIMM that supports 100MHz CPU FSB bus clock. PC-133 DIMM SDRAM DIMM that supports 133MHz CPU FSB bus clock.
PC-1600 or PC-2100 DDR SDRAM PC-1600 DDR SDRAM with a 64-bit data bus doubles the data transfer rate of PC100 SDRAM and hence provides data transfer bandwidth up to 100x64/ 8x2=1600MB/s. PC2100 DDR SDRAM doubles the data transfer rate of PC-133 and hence provides data transfer bandwidth up to 133x64/ 8x2=2100MB/s. PCI (Peripheral Component Interface) Bus A high speed data channel for the internal connection of peripheral devices and the computer system through a PCI expansion card. PnP (Plug and Play) The PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95). These registers are used by BIOS and operating system to configure system resource and prevent any conflicts. PnP BIOS or operating system will automatically allocate the IRQ/ DMA/Memory. Currently, almost all the PCI cards and most ISA cards are already PnP compliant. POST (Power-On Self Test) The BIOS self-test procedure after power-on. It is generally the first or the second program shown on your monitor screen during system boot. RAS (Row Address Strobe) RAS is a technology that DRAM writes and reads to the Row addresses, while a CAS (Column Address Strobe) signal is used to validate the column address. The signals are generally sent CAS before RAS. (in Network field, RAS stands for Remote Access Services). RDRAM (Rambus DRAM) Rambus DRAM is a memory technology that uses large burst mode data transfer of up to 1.6GHz. It is import to know that RDRAM technology helps set up a system level improvement, not just a component upgrade. RIMM (Rambus Inline Memory Module) RIMM is built with a 184-pin architecture module that supports RDRAM memory technology. A RIMM memory module may contain up to maximum of 16 RDRAM devices.

IMPORTANT:
You may figure out the correct processor type by processors OPN (Ordering Part Numbers). Correct CPU external frequency is key to ensure reliability of your system. Incorrect CPU external frequency or overclocking might cause unstable performance, so we strongly recommend to leave SW1 at default setting or legal operation.
2-5-3 BUS RATIO SELECT (BY SW2 DIP1-4/JP17)
The AMD Athlon and Duron processors provide four Frequency ID signals
(FID) respectively via DIP 1 to DIP4 of SW3 for the system controller to specify the SYSTCLK multiplier at which the processor core operates. Normally, the multiplier (or bus ratio) is detected automatically by FID. Therefore, if the processor does not support the function, then Bus Ratio can not be selected. When JP17 is ON, LED LED1 will be on. It means that bus ratio select function is enabled. So as long as your CPU supports bus ratio select function, then the bus ratio can be selected by users.

*Note:

Setting of multipler 12. 5x or above will depend on the type of CPU on board.

Both ISA and PCI expansion cards require IRQs. System IRQs are available to cards installed in the ISA expansion bus first and then any remaining IRQs are available to PCI cards. Currently, there are two types of ISA cards. The original ISA expansion card design, now referred to as Legacy ISA card, requires you to configure the cards jumpers manually and then install it in any available slot on the ISA bus. To see a map of your used and free IRQs in Windows 98, please click the My Computer =Control Panel system, in which you can see the Device Manager tab. Double click on a specific hardware device to display the Resources tab which shows the Interrupt number and address. Double-Clicking the first option Computers of the Device Manager screen to see all the interrupts and addresses for your system. Make sure that ISA devices should not share IRQ with other devices; otherwise your computer will get into trouble when those two devices are used at the same time.

4-5 BIOS UPGRADE

System BIOS is incorporated into a Flash memory component of the mainboard. Flash BIOS allows user to upgrade BIOS without the need to
Chapter4 BIOS Setup replace an EPROM component. The upgrade utility can be loaded on a floppy diskette and used to provide the capability to save, verify, and update the system BIOS. The upgrade utility can also be run from a hard disk drive or a network drive.
4-5-1 BEFORE UPGRADING BIOS
It is highly recommended that you save a copy of the original mainboard BIOS along with a Flash EPROM Programming utility (AWDFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later.

4-5-2 UPGRADE PROCESS

Note: Normally, to upgrade BIOS is unnecessary if the system is working
fine without any problem. Users should not upgrade the BIOS unless you experience incompatible problems or need to create new features. However, please read all information in this section before upgrading. AWDFLASH.EXE is a Flash EPROM Programming utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the mainboard, This program works in DOS environment only, the utility can not be executed in win95/98, ME, NT or WINDOWS 2000 environment.
Upgrading the system BIOS
Step 1. Please visit the board makers website, download latest BIOS file and award flash utility AWDFLASH.EXE. The BIOS file format will be *.bin, of which * stands for the specific file name. Step 2. Create a bootable diskette. Then copy the BIOS file and award flash utility AWDFLASH.EXE into the diskette. Step 3. Insert the diskette into drive A, reboot your system and boot from the diskette. Step 4. Type awdflash *.bin /sn/py/cc and then press <Enter> to run BIOS upgrade program. (*.bin depends on your mainboard model and version code. Instead of typing * , you should type the specific file name for your
75KAV/75KAV-X specific mainboard.) Step 5. Please press <F1> or <F10> to exit or reset your system, Warning ! If the message Write Fail appears while Award FLASH MEMORY WRITER is verifying Flash memory, just repeat the process. Please DO NOT reset or turn off the system. If the award memory flash utility is not able to update the BIOS successfully, your system may not be able to boot up. Step 6. You will need a message CMOS checksum error-Default loaded during booting the system. Press <Del> to run CMOS setup utility, then reload LOAD SETUP DEFAULTS or Load Optimized Defaults and save this change.

If you will be running such a program, we recommend that you disable the virus protection first. CPU Internal Cache/ Cache memory is additional memory that is much External Cache faster than conventional DRAM (system memory). CPUs from 486-type up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory.
