~ Page 28 ~.
~ Page 29 ~ 4 - 1. BIOS SETU P OVERVIEW The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the PCI bus and connected devices such as the video display, diskette drive, and the keyboard. The BIOS provides a menu - based interface to the console subsystem.
~ Page 30 ~ 4 - 2. STANDARD CMOS SETUP The <Standard CMOS Setup> option allows you to record some basic system hardware configurations and set the system clock and error handling. If the CPU board is already in stalled in a working system, you will not need to select this option anymore.
~ Page 31 ~ errors. 4 - 3. ADVANCED CMOS SETUP The <Advanced CMOS Setup> option consists of configuration entries that allow you to improve your system performance, or let you set up some system features according to your preference. Some entries here are required by the CPU board’s design to remain in their default settings.
~ Page 32 ~ HDD Access Control This option determines the hard disk access method, whi ch can be either read only or normal (read/write). When set to read only, the data in the hard disk is allowed to be read instead of being written.” Normal” allows the floppy to be read or written.
~ Page 33 ~ Hit ‘DEL’ Message Display Set this option to Disabled to prevent the following message: Hit ‘DEL’ if you want to run setup It will prevent the message from appearing on the first BIOS screen when the computer boots. Internal Cache This option specifies the caching algorithm used for the L1 internal cache memory.
~ Page 34 ~ 4 - 4. ADVANCED CHIPSET SETUP This option controls the configuration of the board’s chipset. Control keys for this screen are the same as for the previous screen. BIOS: Advanced Chipset Setup Configure SDRAM Timing by SPD: SPD is the a bbreviation Serial Presence Detect.
~ Page 35 ~ Memory Hole at 15 - 16 MB This option specifies the range 15MB to 16MB in memory that cannot be addressed on the ISA bus. USB Function This option can enable or disable USB function USB Keybo ard/Mouse Legacy Support These options are used to < Enabled > the USB function and it’s only useful in the DOS mode.
~ Page 36 ~ 4 - 5. POWER MANAGEMENT This section is used to configure the po wer management features. This <Power management Setup> option allows you to reduce power consumption. This feature turns off the video display and shuts down the hard disk after a period of inactivity.
~ Page 37 ~ Suspend Time Out(minute) These options specify the length of the period of system inactivity when the computer is already in Standby mode before the computer is placed on Suspend mode.
~ Page 38 ~ 4 - 6. PCI/PLUG AND PLAY This section is used to configure PCI / Plug and Play features. The <PCI & PNP Setup> option configures the PCI bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value.
~ Page 39 ~ PCI VGA Palette Snoop This ite m is for BIOS to snoop the appearance of VGA palette, and modify it when necessary. PCI IDE BusMaster When Enabled this option specifies that the IDE controller on the PCI local bus has bus mastering capability.
~ Page 40 ~ 4 - 7. PERIPHERAL SETUP This section is used to configure the peripheral features. BIOS: Peri pheral Setup OnBoard FDC This option enables the floppy drive controller on the AR - B1682. OnBoard Serial Port This option enables the serial port on the AR - B1682.
~ Page 41 ~ OnBoard IDE This option is to set up the operating mode of IDE controller. If the main board offer the enhanced I/O port, the choice should be < enabled > . Reset, Power, Sleep Button These options are to activate the Reset, Power, and Sleep function in the ATX Keyboard.
~ Page 42 ~ these items to quickly set system configuration parameters, you can choose a group of settings that have a better chance of working when the system is havi ng configuration related problems. 4 - 12 - 1. Auto Configuration with Optimal Setting The user can load the optimal default settings for the BIOS.
~ Page 43 ~ Step 1: Turn on your system and don’t detect the CONFIG.SYS and AUTOEXEC.BAT files. Step 2: Insert the FLASH BIOS diskette into the floppy disk drive.
