13 Chapter 2 Installations CPU Installation The PC-586U(PC) Industrial CPU Card supports a ZIF processor socket for Pentium-level processors. Unlike PGA sockets, ZIF (Zero Insertion Force) sockets come with a lever to secure the processor. Make sure the notch on the corner of the CPU corresponds with the notch on the inside of the socket. After you have installed the processor into the ZIF socket, check if the jumpers for the CPU type and speed are correct. NOTE: Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU overheating problem that would cause your system to hang or be unstable. 8 PC-586U(PC) User s Manual

48 Chapter 3 BIOS Configuration BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system s ROM supports Intel/Cyrix/AMD processors in a standard IBM-AT compatible I/O system. The BIOS provides critical low-level support for standard devices such as disk drives, serial and parallel ports. It also adds virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system. BIOS Setup The Award BIOS provides a Setup utility program for specifying the system configurations and settings. The BIOS ROM of the system stores the Setup utility. When you turn on the computer, the Award BIOS is immediately activated. Pressing the <Del> key immediately allows you to enter the Setup utility. If you are a little bit late pressing the <Del> key, POST(Power On Self Test) will continue with its test routines, thus preventing you from invoking the Setup. If you still wish to enter Setup, restart the system by pressing the Reset button or simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the system Off and back On again. The following message will appear on the screen: Press <DEL> to Enter Setup In general, you press the arrow keys to highlight items, <Enter> to select, the <PgUp> and <PgDn> keys to change entries, <F1> for help and <Esc> to quit. When you enter the Setup utility, the Main Menu screen will appear on the screen. The Main Menu allows you to select from various setup functions and exit choices. 44 PC-586U(PC) User s Manual

Primary HDDs / Secondary HDDs The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first is the Master and the second is the Slave. To enter the specifications for a hard disk drive, you must select first a Type. There are 45 predefined types and 4 user definable types are for Enhanced IDE BIOS. Type 1 to 45 are predefined. Type User is user-definable. For the Primary Master/Slave as well as Secondary Master/Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE drives and CD-ROM drive during POST. Press <PgUp>/<PgDn> to select a numbered hard disk type or type the number and press the <Enter> key. The hard disk will not work properly if you enter incorrect information for this field. If your hard disk drive type is not matched or listed, you can use Type User to define your own drive type manually. If you select Type User, related information is asked to be entered to the following items. CYLS : Number of cylinders HEAD : Number of read/write heads PRECOMP : Write precompensation LANDZ : Landing zone SECTOR : Number of sectors SIZE : Automatically adjust according to the configuration MODE (for IDE HDD only) : Auto Normal (HD < 528MB) Large (for MS-DOS only) LBA (HD > 528MB and supports Logical Block Addressing) NOTE: The specifications of your drive must match with the drive table.

If this occurs, you can either allow the operation to continue or run an anti-virus program to locate and remove the problem. NOTE: Many disk diagnostic programs which attempt to access the boot sector table can cause the virus warning. If you will run such a program, disable the Virus Warning feature. CPU Internal Cache / External Cache These items allow you to enable (speed up memory access) or disable the cache function. By default, these items are Enabled.

Swap Floppy Drive This item allows you to determine whether to enable the swap Floppy Drive or not. When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes Drive B, and Drive B becomes Drive A. By default, this field is set to Disabled. Boot Up Floppy Seek When enabled, the BIOS will seek whether or not the floppy drive installed has 40 or 80 tracks. 360K type has 40 tracks while 760K, 1.2M and 1.44M all have 80 tracks. By default, this field is set to Enabled. Boot Up NumLock Status This allows you to activate the NumLock function after you power up the system. By default, the system boots up with NumLock On. Security Option This field allows you to limit access to the System and Setup. The default value is Setup. When you select System, the system prompts for the User Password every time you boot up. When you select Setup, the system always boots up and prompts for the Supervisor Password only when the Setup utility is called up.

Expansion cards can only access memory up to 16MB. By default, this field is set to Disabled. PCI 2.1 Compliance Concurrent PCI allows multiple PCI transfers from the PCI master buses to memory to CPU. By default, this field is set to Enabled. CPU Warning Temperature The onboard hardware thermal sensor monitors CPU temperature changes and prevents the CPU from overheating. Alert is sounded through the speaker and CPU speed slows down when the temperature exceeds the temperature set in the BIOS until the temperature falls below a safe level. By default, this field is set to 70 C/158 F. Temperature/Fan Speeds/Voltages These read-only fields show the current CPU temperature, speeds in RPM (revolution per minute) for the CPU fan and chassis fan, and current voltages in the voltage regulators and power supply as monitored by the hardware monitoring IC.

59 Chapter 3 BIOS Configuration Video Off After This field specifies the mode after which the Video Off feature is enabled. The options are Doze, Standby, Suspend, and N/A. Doze Mode When enabled, and after the set time of system inactivity, the CPU clock will run at a slower speed while all other devices still operate at full speed. Standby Mode When enabled, and after the set time of system inactivity, the fixed disk drive and the video would be shut off while all other devices still operate at full speed. Suspend Mode When enabled, and after the set time of system inactivity, all devices except the CPU will be shut off. HDD Power Down When enabled, and after the set time of system inactivity, the hard disk drive will be powered down while all other devices remain active. Soft-Off by PWR-BTTN This field defines the power-off mode when using an ATX power supply. The Instant-Off mode allows powering off immediately upon pressing the power button. In the Delay 4 Sec mode, the system powers off when the power button is pressed for more than four seconds or places the system in a very low-power-usage state, with only enough circuitry receiving power to detect power button activity. The default value is Instant-Off. Resume by Alarm This allows the system to be turned on automatically through the timer set in the BIOS to make the system more scheduleable.
