4-4 WHAT IS POST

POST is an acronym for Power On Self Test. POST will that all things the BIOS does before the operating system is started. Each of POST routines is assigned a POST code, a unique number which is sent to I/O port 080h before the routine is executed.

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.

Chapter4 BIOS Setup Virus Warning Enabled: Activates automatically when the system boots up showing a warning message if anything attempts to access the boot sector or hard disk partition table. Disabled: No warning message will appear when there is something attempting to access the boot sector or hard disk partition table. NOTE: Many diagnostic (or boot manager) programs which attempt to access the boot sector table can cause the above warning message. 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. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU.

Press DEL to enter SETUP

4-3 WHAT IS CMOS
CMOS is the memory maintained by a battery. The BIOS uses CMOS to store the settings you have selected in SETUP. The CMOS also maintains the internal clock. Every time you turn on your computer, the BIOS Looks into CMOS for the settings you have selected and configures your computer accordingly. If the battery is out of power, the CMOS data will be lost and POST will issue a CMOS invalid or CMOS checksum invalid message. If this happens, you have to replace the battery and do some proper settings in SETUP.

4-4 WHAT IS POST

POST is an acronym for Power On Self Test. POST will test all things the BIOS does before the operating system is started. Each of POST routines is assigned a POST code, a unique number which is sent to I/O port 080h before the routine is executed.

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 replace an EPROM component. 49
The upgrade utility can be loaded on a floppy diskette and used to provides the capability to save, verify, and update the system BIOS. The upgrade utility can 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 only 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 form 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 specific file name for your 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.

Award Flash Memory Writer Start Screen
Award Flash Memory Writer Complete Screen
The parameters of AWDFLASH.EXE /sn: No original BIOS backup /py: Program flash memory /cc: Clear CMOS data (and update data automatically) after programming
NOTE: Users can type AWDFLASH /? to get further details about the parameters. Incorrect usage of the parameter will damage the BIOS information, so we strongly recommend user to leave parameters alone unless you fully understand their function.

Virus Warning When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an antivirus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive.
NOTE: Many disk diagnostic programs that access the boot sector
table can trigger the virus warning message. If you plan to run such a program, we recommend that you disable the virus warning.
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. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for faster access by the CPU.
CPU L2 Cache ECC When you select Enabled, it will speed up memory Checking checking when the external cache contains ECC SRAMs. The choices: Enabled; Disabled. 59

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.
SDRAM (Synchronous DRAM) SDRAM is one of the Dynamic Random Access Memory (DRAM) technologies that allow DRAM to use the same clock as the CPU host clock (EDO and FPM are asynchronous and do not have clock signal). SDRAM comes in 64-bit 168-pin DIMM and operates at 3.3V. SIMM (Single In Line Memory Module) SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it is called Single In Line. SIMM is made of FPM or EDO DRAM and supports 32-bit data. SIMM is phased out in current mainboard design. SPD (Serial Presence Detect) SPD is a small ROM or EEPROM device resided on the DIMM or RIMM. Memory module information such as DRAM timing and chip parameters can be stored into SPD so that BIOS can access it and use it to decide best timing for this DIMM or RIMM. UART (Universal Asynchronous Receiver/transmitter) UART is built in a chip that controls the data sent to and received from a serial port. A 16550 UART is now standard in most PCs, and supports modem speed up to 57,600 bps and beyond and direct connect speed of 115,200 bps. Many UARTs have built-in errors in the internal code and just do not work correctly with many external modems. UART is also found as the serial interface on internal modem. Ultra DMA Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data at 33.3MB/s between a hard disk drive through the computers data path (or bus) to the computers random access memory (RAM). The transfer data is twice as fast as the previous Direct Access Memory (DMA) interface. The latest Ultra DMA has advanced to Ultra DMA/66 and Ultra DMA/100. 16.6MB/s x2 = 33MB/s 16.6MB/s x4 = 66MB/s 16.6MB/s x6 = 100MB/s
