Introduction to Setup
This manual describes the Phoenix Technologies AwardBIOS Setup program. The Setup program lets you modify basic system configuration settings. The settings are then stored in a dedicated battery-backed memory, called CMOS RAM, that retains the information when the power is turned off.
The Phoenix Technologies AwardBIOS in your computer is a customized version of an industry­standard BIOS for IBM PC AT-compatible personal computers. It supports Intel x86 and compatible processors. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems.
The Phoenix Technologies AwardBIOS has been customized by adding important, but nonstandard, features such as virus and password protection, power management, and detailed fine-tuning of the chipset controlling the system.
The rest of this manual is intended to guide you through the process of configuring your system using Setup.
Starting Setup
The Phoenix Technologies AwardBIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST).
When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.
To start Setup, press the Del key some time before or while a message similar to this appears briefly at the bottom of the screen during POST:
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you press DEL and you still wish to enter Setup, you must
reboot the system.

Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press Esc or the F1 key again.
In Case of Problems
If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the Phoenix Technologies AwardBIOS supports an override to the CMOS settings that resets your system to its default configuration.
You can invoke this override by immediately pressing Insert; when you restart your computer. You can restart by either using the ON/OFF switch, the RESET button or by pressing Ctrl-Alt­Delete.
The best advice is to alter only settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without a good reason. The Chipset defaults have been carefully chosen by Phoenix Technologies or your system manufacturer for the best performance and reliability. Even a seemingly small change to the Chipset setup may causing the system to become unstable.
Setup Variations
Not all systems have the same Setup. While the basic look and function of the Setup program remains the same for all systems, your Setup screens may differ from the screens described here. Each system design and chipset combination require custom configurations. In addition, the final appearance of the Setup program depends on your system designer. Your system designer can decide that certain items should not be available for user configuration and remove them from the Setup program.

Main Setup Menu
When you enter the Phoenix Technologies AwardBIOS CMOS Setup Utility, a Main Menu appears on the screen. The Main Menu allows you to select from several Setup functions and two exit choices. Use the arrow keys to select among the items and press Enter to accept and enter the sub-menu.
A brief description of each highlighted selection appears at the bottom of the screen. Following is a brief summary of each Setup category.
Standard CMOS BIOS Features Chipset Features Power Management PnP/PCI Configuration Integrated Peripherals Supervisor/Us er Password Setting IDE HDD Auto Detection HDD Low Level Format

Options in the original PC AT-compatible BIOS.
Phoenix Technologies enhanced BIOS options.
Options specific to your system chipset.
Advanced Power Management (APM) options.
Plug and Play standard and PCI Local Bus configuration options.
I/O subsystems that depend on the integrated peripherals controller in your system. Change, set, or disable a password. In BIOS versions that allow separate user and supervisor passwords, only the supervisor password permits access to Setup. The user password generally allows only power-on access. Automatically detect and configure IDE hard disk parameters.
This option does not appear in many BIOS versions. Most manufacturers of IDE hard drives strongly recommend that you do not run a low-level format on their drives, because of the danger that the bad-track table may be over-written. Phoenix Technologies supplies this utility for service personnel only. If you feel that you need to run a low-level format on your hard drive, contact your drive
manufacturer for instructions!
BIOS defaults are factory settings for the most stable, minimal-performance system operations. Setup defaults are factory settings for optimal-performance system operations.
Save settings in nonvolatile CMOS RAM and exit Setup.
Abandon all changes and exit Setup.

Standard CMOS Setup
In the Standard CMOS menu you can set the system clock and calendar, record disk drive parameters and the video subsystem type, and select the type of errors that stop the BIOS POST.
Date
The BIOS determines the day of the week from the other date information. This field is for information only.
Press the left or right arrow key to move to the desired field (date, month, year). Press the PgUp or PgDn key to increment the setting, or type the desired value into the field.
Time
The time format is based on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp or PgDn key to increment the setting, or type the desired value into the field.
Daylight Saving
This category may not be present in your Setup program. When enabled, it adds one hour to the clock when daylight-saving time begins. It also subtracts one hour when standard time returns.
HARD DISKS
The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI drives.
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type are available:
1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45.
6
2. Select USER and enter values into each drive parameter field.
3. Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a
specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any pre­defined type are classified as type USER.
. Size: Disk drive capacity (approximate). Note that this size is usually slightly greater than
•
the size of a formatted disk given by a disk-checking program.
. Cyls: Number of cylinders
•
. Head: Number of heads
•
. Precomp: Write precompensation cylinder
•
. Landz: Landing zone
•
. Sector: Number of sectors
•
. Mode: Auto, Normal, large, or LBA
•
Auto: The BIOS automatically determines the optimal mode.
. Normal: Maximum number of cylinders, heads, and sectors supported are 1024,
•
16, and 63.
. Large: For drives that do not support LBA and have more than 1024 cylinders.
•
. LBA (Logical Block Addressing): During drive accesses, the IDE controller
•
transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders.

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. All errors If the BIOS detects any non-fatal error, POST
stops and prompts you to take corrective action.
All, POST does not stop for a keyboard error, but But Keyboard stops for all other errors.
All, But POST does not stop for diskette drive errors, Diskette but stops for all other errors.
All, But POST does not stop for a keyboard or disk Disk/Key error, but stops for all other errors.
Memory
You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
8
RAM is the computer's working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory.
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stay­resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory.
