CPU Heatsink Installation To install CPU heatsink, please be aware of the orientation of it. Align the end of CPU Fan power cable to the top-left in order to mount it easily. The solided side of heatsink that to be secured by screws CPU Fan power socket Use tool-free screws to secure heatsink The holes that secure the heatsink Warning: Insert the CPU fan powe cable into the socket and place the heatsink into position.
AWARD BIOS Setup The AR-B1740 uses the Award PCI/ISA BIOS for the system configuration. The Award BIOS setup program is designed to provide the maximum flexibility in configuring the system by offering various options which could be selected for end-user requirements. This chapter is written to assist you in the proper usage of these features. To access AWARD PCI/ISA BIOS Setup program, press key. The Main Menu will be displayed at this time.
Standard CMOS Setup Video Select the type of primary video subsystem in your computer. The BIOS usually detects the correct video type automatically. The BIOS supports a secondary video subsystem, but you do not select it in Setup. Halt On During the power-on self-test (POST), the computer stops if the BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections: No errors POST does not stop for any errors.
BIOS Features Setup CPU L1 & L2 Cache Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache memory, and most, but not all, CPU L3 Cache This item allows you to enable/disable CPU L3 Cache. The choice: Enabled, Disabled. Quick Power On Self Test This category speeds up Power On Self Test (POST) after you power up the computer. If it is set to Enable, BIOS will shorten or skip some check items during POST.
Advanced Chipset Features Security Option Select whether the password is required every time the system boots or only when you enter setup. System The system will not boot and access to Setup will be denied if the correct password is not entered at the prompt. Setup The system will boot, but access to Setup will be denied if the correct password is not entered at the prompt. Note To disable security, select PASSWORD SETTING at Main Menu and then you will be asked to enter password.
DRAM RAS Precharge The third part of the x-y-z notation used in SDRAM, the other two being CAS and RAS to CAS. Like its brethren, it's better lower but also more stressful lower. See the pattern 2.5 is only available with DDR. On-Chip VGA If your system contains a VGA controller and you want to activate it, select Enabled. The next option will become available. DRAM Data Integrity Mode This BIOS feature controls the ECC feature of the memory controller.
Integrated Peripherals OnChip Primary/Seconary IDE Select "Enabled" to activate each on-board IDE channel separately, Select "Disabled", if you install an add-on IDE Control card IDE HDD Block Mode This feature enhances disk performance by allowing multi-sector data transfers and eliminates the interrupt handling time for each sector. [Sub Menu] [Sub Menu] USB Controller Select "Enabled" to activate USB Controller, Select "Disabled", if you want to disable USB Controller. USB 2.
Power Management Setup AC97 Audio AC97 Audio selection. Init Display First Select "AGP" or "PCI Slot" for system to detect first when boot-up. Onboard LAN 1 & 2 Select "Enabled" if your system contains onboard LAN 1 & 2 supports. Power-Supply Type Select the power-supply type. Power Management There are 4 selections for Power Management, 3 of which have fixed mode : Disabled (default) No power management. Disables all four modes. Min. Power Saving Minimum power management. Doze Mode = 1 hr.
PC Health Status Video Off Option Controls what causes the display to be switched off Suspend -> Off Always On All Mode -> Off Video Off In Suspend Controls what causes the display to be switched off Suspend -> Off Always On All Mode -> Off Suspend Type S1 (POS) Power On suspend All devices are powered up except for the clock synthesizer. The Host and PCI clocks are inactive and PIIX4 provides control signals and 32-kHz Suspend Clock (SUSCLK) to allow for DRAM refresh and to turn off the clock synthesizer.
Frequency/Voltage Control POST Codes The following codes are not displayed on the screen. They can only be viewed on the LED display of a so called POST card. The codes are listened in the same order as the according functions are executed at PC startup. If you have access to a POST Card reader, you can watch the system perform each test by the value that's displayed.

How to flash the BIOS AR-B1740 User's Manual To flash your BIOS you'll need 1) a xxxxx.bin file that is a file image of the new BIOS 2) AWDFLASH.EXE a utility that can write the data-file into the BIOS chip. The procedure: Create a new, clean DOS (6 or higher) bootable floppy with "format a: /s". Copy flash utility and the BIOS image file to this disk.
