Section 2 -- Standard CMOS Setup
Appendix C -- BIOS Default Drive Table
Appendix D -- Low-Level Format Utility
This manual discusses Award's Setup program built into the ROM BIOS. The Setup program allows users to modify the basic system configuration. This special information is then stored in battery-backed RAM so that it retains the Setup information when the power is turned off.
The Award BIOS installed in your computer system's ROM (Read Only Memory) is a custom version of an industry standard BIOS. This means that it supports Intel/Cyrix/AMD processors in a standard IBM-AT compatible input/output system. The BIOS provides critical low-level support for standard devices such as disk drives and serial and parallel ports.
The Award BIOS has been customized by adding important, but non-standard, features such as virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system.
The rest of this manual is intended to guide you through the process of configuring your system using Setup.
The Award BIOS is immediately activated when you first power on the computer. The BIOS reads the system information contained in the CMOS and begins the process of checking out the system and configuring it. When it finishes, the BIOS will seek an operating system on one of the disks and then launch and turn control over to the operating system.
While the BIOS is in control, the Setup program can be activated in one of two ways:
PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP
In general, you use the arrow keys to highlight items, press <Enter> to select, use the PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit. The following table provides more detail about how to navigate in the Setup program using the keyboard.
Up arrow Move to previous item Down arrow Move to next item Left arrow Move to the item in the left hand Right arrow Move to the item in the right hand Esc key Main Menu -- Quit and not save changes into CMOS Status Page Setup Menu and Option Page Setup Menu -- Exit current page and return to Main Menu PgUp key Increase the numeric value or make changes PgDn key Decrease the numeric value or make changes + key Increase the numberic value or make changes - key Decrease the numberic value or make changes F1 key General help, only for Status Page Setup Menu and Option Page Setup Menu (Shift)F2 Change color from total 16 colors. F2 to select key color forward, (Shift) F2 to select color backward F3 key Calendar, only for Status Page Setup Menu F4 key Reserved F5 key Restore the previous CMOS value from CMOS, only for Option Page Setup Menu F6 key Load the default CMOS value from BIOS default table, only for Option Page Setup Menu F7 key Load the default F8 key Reserved F9 key Reserved F10 key Save all the CMOS changes, only for Main Menu
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.
If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the Award BIOS supports an override to the CMOS settings which resets your system to its defaults.
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>, <Alt> and <Delete> at the same time.
The best advice is to only alter settings which you thoroughly understand. To this end, we strongly recommend that you avoid making any changes to the chipset defaults. These defaults have been carefully chosen by both Award and your systems manufacturer to provide the absolute maximum performance and reliability. Even a seemingly small change to the chipset setup has the potential for causing you to use the override.
Not all systems have the same Setup. While the basic look and function of the Setup program remains the same for all systems, individual motherboard and chipset combinations require custom configurations. For example, you may find that your Setup main menu has a different number of entries from the main menu displayed in this manual. These are simply features not supported (or not user configurable) on your system.
The final appearance of the Setup program also depends on the Original Equipment Manufacturer (OEM) who built your system. If your OEM has decided that certain items should only be available to their technicians, those items may very well be removed from the Setup program.
Main Menu
Once you enter the Award BIOS CMOS Setup Utility, the Main Menu will appear 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.
Note that a brief description of each highlighted selection appears at the bottom of the screen.
The main menu includes the following main setup categories. Recall that some systems may not include all entries.
This setup page includes all the items in a standard, AT-compatible BIOS. See Section 2 for details.
This setup page includes all the items of Award special enhanced features. See Section 3 for details.
Change, set, or disable password. It allows you to limit access to the system and Setup, or just to Setup. See Section 4.
This setup page includes all the items of chipset special features. See Section 5 for details.
This entry only appears if your system supports Power Management, "Green PC", standards. See Section 6 for setup details.
This entry only appears if your system supports PCI. See Section 8, if your system supports Power Management, otherwise see Section 7.
The BIOS defaults have been set by the manufacturer and represent settings which provide the minimum requirements for your system to operate.
The chipset defaults are settings which provide for maximum system performance. While Award has designed the custom BIOS to maximize performance, the manufacturer has the right to change these defaults to meet their needs.
Automatically detect and configure hard disk parameters. The Award BIOS includes this ability in the event you are uncertain of your hard disk's paramenters. See also Section 2, "Standard CMOS Setup".
If supported by your system, this provides a hard disk low level format utility. See Appendix D for details.
Save CMOS value changes to CMOS and exit setup.
Abandon all CMOS value changes and exit setup.
Standard CMOS Setup
The items in Standard CMOS Setup Menu are divided into 10 categories. Each category includes no, one or more than one setup items. Use the arrow keys to highlight the item and then use the <PgUp> or <PgDn> keys to select the value you want in each item.
The date format is <day>, <date> <month> <year>. Press <F3> to show the calendar.
day The day, from Sun to Sat, determined by the BIOS and is display-only date The date, from 1 to 31 (or the maximum allowed in the month) month The month, Jan through Dec year The year, from 1900 through 2099
The time format is <hour> <minute> <second>. The time is calculated based on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00.
The category adds one hour to the clock when daylight-saving time begins. It also subtracts one hour when standard time returns.
Enabled Enable daylight-saving Disabled Disable daylight-saving
The categories identify the types of hard disk drive C or drive D that have been installed in the computer. There are 46 predefined types and a user definable type. Type 1 to Type 46 are predefined. Type "User" is user-definable.
Press PgUp or PgDn to select a numbered hard disk type or type the number and press <Enter>. Note that the specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper information for this category. 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", you will need to know the information listed below. Enter the information directly from the keyboard and press <Enter>. This information should be included in the documentation from your hard disk vendor or the system manufacturer.
CYLS. number of cylinders HEADS number of heads PRECOMP write precom LANDZONE landing zone SECTORS number of sectors
If a hard disk has not been installed select NONE and press <Enter>.
The category identifies the types of floppy disk drive A or drive B that have been installed in the computer.
None No floppy drive installed 360K, 5.25 in 5-1/4 inch PC-type standard drive; 360 kilobyte capacity 1.2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity 720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity 1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity 2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity
The category selects the type of video adapter used for the primary system monitor. Although secondary monitors are supported, you do not have to select the type in Setup.
EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA, SEGA, SVGA or PGA monitor adapters. CGA 40 Color Graphics Adapter, power up in 40 column mode CGA 80 Color Graphics Adapter, power up in 80 column mode MONO Monochrome adapter, includes high resolution monochrome adapters
The category determines whether the computer will stop if an error is detected during power up.
No errors Whenever the BIOS detects a non-fatal error the system will be stopped and you will be prompted. All errors The system boot will not be stopped for any error that may be detected. All, The system boot will not stop for a keyboard But Keyboard error; it will stop for all other errors. All, But The system boot will not stop for a disk error; Diskette it will stop for all other errors. All, But The system boot will not stop for a keyboard or Disk/Key disk error; it will stop for all other errors.
The category is display-only which is determined by POST (Power On Self Test) of the BIOS.
The POST will determine the amount of base (or conventional) memory installed in the system. The value of the base memory is typically 512K for systems with 512K memory installed on the motherboard, or 640K for systems with 640K or more memory installed on the motherboard.
The BIOS determines how much extended memory is present during the POST. This is the amount of memory located above 1MB in the CPU's memory address map.
Expanded Memory is memory defined by the Lotus/Intel/Microsoft (LIM) standard as EMS. While most standard DOS applications cannot access memory above 640K, the Expanded Memory Specification (EMS) provides an interface allowing access to all system memory. While still in use by some DOS applications, EMS is rapidly declining in importance since new processors and operating systems prefer extended memory.
A special, expanded memory device driver is required to use memory as Expanded Memory.
This refers to the memory located in the 640K to 1024K address space. This is memory that can be used for different applications. DOS uses this area to load device drivers in an effort to keep as much base memory free for application programs. The BIOS is the most frequent user of this RAM area since this is where it shadows RAM.
Password Setting
When you select this function, the following message will appear at the center of the screen to assist you in creating a password.
ENTER PASSWORD:
Type the password, up to eight characters in length, and press <Enter>. The password typed now will clear any previously entered password from CMOS memory. You will be asked to confirm the password. Type the password again and press <Enter>. You may also press <Esc> to abort the selection and not enter a password.
To disable a password, just press <Enter> when you are prompted to enter the password. A message will confirm the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup freely.
PASSWORD DISABLED.
When a password has been enabled, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to request a password every time your system is rebooted. This would prevent unauthorized use of your computer.
You determine when the password is required within the BIOS Features Setup Menu and its Security option (see Section 4). If the Security option is set to "System", the password will be required both at boot and at entry to Setup. If set to "Setup", prompting only occurs when trying to enter Setup.

These three sections, if applicable, are specific to individual systems and are not included with this document.
POST Messages
During the Power On Self Test (POST), if the BIOS detects an error requiring you to do something to fix, it will either sound a beep code or display a message.
If a message is displayed, it will be accompanied by:
PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP
Currently there is only one beep code in BIOS. This code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps.
One or more of the following messages may be displayed if the BIOS detects an error during the POST. This list includes messages for both the ISA and the EISA BIOS.
CMOS battery is no longer functional. It should be replaced.
Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This error may have been caused by a weak battery. Check the battery and replace if necessary.
No boot device was found. This could mean that either a boot drive was not detected or the drive does not contain proper system boot files. Insert a system disk into Drive A: and press <Enter>. If you assumed the system would boot from the hard drive, make sure the controller is inserted correctly and all cables are properly attached. Also be sure the disk is formatted as a boot device. Then reboot the system.
Type of diskette drive installed in the system is different from the CMOS definition. Run Setup to reconfigure the drive type correctly.
Display switch on the motherboard can be set to either monochrome or color. This indicates the switch is set to a different setting than indicated in Setup. Determine which setting is correct,and then either turn off the system and change the jumper, or enter Setup and change the VIDEO selection.
Since last powering off the system, the display adapter has been changed. You must configure the system for the new display type.
The EISA non-volatile RAM checksum is incorrect or cannot correctly read the EISA slot. This can indicate either the EISA non-volatile memory has become corrupt or the slot has been configured incorrectly. Also be sure the card is installed firmly in the slot.
The slot configuration information stored in the EISA non-volatile memory is incomplete.
Note: When either of these errors appear, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
Hard drive cannot be initialized. Be sure the adapter is installed correctly and all cables are correctly and firmly attached. Also be sure the correct hard drive type is selected in Setup.
Cannot initialize controller. Make sure the cord is correctly and firmly installed in the bus. Be sure the correct hard drive type is selected in Setup. Also check to see if any jumper needs to be set correctly on the hard drive.
Cannot find or initialize the floppy drive controller. make sure the controller is installed correctly and firmly. If there are no floppy drives installed, be sure the Diskette Drive selection in Setup is set to NONE.
The non-volatile memory containing EISA configuration information was programmed incorrectly or has become corrupt. Re-run EISA configuration utility to correctly program the memory.
NOTE: When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys are being pressed during the boot.
If you are purposely configurating the system without a keyboard, set the error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. This will cause the BIOS to ignore the missing keyboard and continue the boot.
Indicates a memory address error at a specific location. You can use this location along with the memory map for your system to find and replace the bad memory chips.
Indicates a memory parity error at a specific location. You can use this location along with the memory map for your system to find and replace the bad memory chips.
Memory has been added or removed since the last boot. In EISA mode use Configuration Utility to reconfigure the memory configuration. In ISA mode enter Setup and enter the new memory size in the memory fields.
Indicates an error verifying a value already written to memory. Use the location along with your system's memory map to locate the bad chip.
This message is used in conjunction with the I/O CHANNEL CHECK and RAM PARITY ERROR messages when the segment that has caused the problem cannot be isolated.
This message is used in conjunction with the I/O CHANNEL CHECK and RAM PARITY ERROR messages when the segment that has caused the problem has been isolated.
This will be displayed at the bottom screen when an error occurs that requires you to reboot. Press any key and the system will reboot.
When BIOS detects a Non-maskable Interrupt condition during boot, this will allow you to disable the NMI and continue to boot, or you can reboot the system with the NMI enabled.
Indicates a parity error in Random Access Memory.
A valid board ID was found in a slot that was configurated as having no board ID.
NOTE; When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
The board installed is not responding to the ID request, or no board ID has been found in the indicated slot.
NOTE: When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
Indicates that a slot designated as empty by the EISA Configuration Utility actually contains a board.
NOTE: When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
Indicates the present boot attempt has been aborted and the system must be rebooted. Press and hold down the CTRL and ALT keys and press DEL.
The board ID does not match the ID stored in the EISA non-volatile memory.
NOTE: When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
