2.1.3 Intelligence
Auto Fan Off: The system fans powers off automatically even in sleep mode. This function reduces both energy consumption and system noise, and is an important feature in implementing silent PC systems. Dual Function Power Button: Pushing the power button for less than 4 seconds when the system is in the working state places the system into one of two states: sleep mode or soft-off mode, depending on the BIOS or OS setting (see PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting. Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds. Power LED (requires ACPI OS support): The power LED indicates the system status. Remote Ring-On (requires modem): This allows a computer to be turned on remotely through an internal or external modem. With this benefit on-hand, users can access vital information from their computers anywhere. System Resources Alert: Todays operating systems such as Windows 95/98/ NT and OS/2, require much more memory and hard drive space to present enormous user interfaces and run large applications. The system resource monitor warns the user before the system resources are used up to prevent possible application crashes. Suggestions provide the user some information on managing their limited resources more efficiently. Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPUs internal thermal diode (on Pentium III and Celeron) to prevent system overheat and system damage. Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable voltage to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management. Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

4. BIOS SETUP

4.1 Managing and Updating Your BIOS
4.1.1 Upon First Use of the Computer System
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created. NOTE: AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk. 3. Reboot the computer from the floppy disk. NOTE: BIOS setup must specify Floppy as the first item in the boot sequence. 4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
IMPORTANT! If the word unknown appears after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility.
4. BIOS SETUP Updating BIOS
5. Select 1. Save Current BIOS to File from the Main menu and press <Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX and then press <Enter>.

WARNING! Update the BIOS only if you have problems with the motherboard and you know that the new BIOS revision will solve your problems. Careless updating can result in your motherboard having more problems! 1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) (see ASUS CONTACT INFORMATION on page 3 for details) and save to the boot floppy disk you created earlier. 2. Boot from the floppy disk. 3. At the A:\ prompt, type AFLASH and then press <Enter>. 4. At the Main Menu, type 2 then press <Enter>. The Update BIOS Including Boot Block and ESCD screen appears. 5. Type the filename of your new BIOS and the path, for example, A:\XXXXX.XXX, then press <Enter>. NOTE: To cancel this operation, press <Enter>.

4.3 Main Menu

When you enter the Setup program, the following screen appears:
System Time [XX:XX:XX] Sets the system to the time that you specify (usually the current time). The format is hour, minute, second. Valid values for hour, minute and second are Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59). Use the <Tab> or <Shift> + <Tab> keys to move between the hour, minute, and second fields. System Date [XX/XX/XXXX] Sets the system to the date that you specify (usually the current date). The format is month, day, year. Valid values for month, day, and year are Month: (1 to 12), Day: (1 to 31), Year: (100 year range). Use the <Tab> or <Shift> + <Tab> keys to move between the month, day, and year fields. Legacy Diskette A [1.44M, 3.5 in.], Legacy Diskette B [None] Sets the type of floppy drives installed. Configuration options: [None] [360K, 5.25 in.] [1.2M , 5.25 in.] [720K , 3.5 in.] [1.44M, 3.5 in.] [2.88M, 3.5 in.] Floppy 3 Mode Support [Disabled] This is required to support older Japanese floppy drives. The Floppy 3 Mode feature allows reading and writing of 1.2MB (as opposed to 1.44MB) on a 3.5-inch diskette. Configuration options: [Disabled] [Enabled]

4. BIOS SETUP Main Menu

4.3.1 Primary & Secondary Master/Slave
Type [Auto] Select [Auto] to automatically detect an IDE hard disk drive. If automatic detection is successful, Setup automatically fills in the correct values for the remaining fields on this sub-menu. If automatic detection fails, this may be because the hard disk drive is too old or too new. Try updating the BIOS or manually entering the IDE hard disk drive parameters. NOTE: After entering the IDE hard disk drive information into BIOS, use a disk utility, such as FDISK, to partition and format new IDE hard disk drives. This is necessary so that you can write or read data from the hard disk. Make sure to set the partition of the Primary IDE hard disk drives to active. Other options for the Type field are: [None] - to disable IDE devices
4. BIOS SETUP Master/Slave Drives
NOTE: Before attempting to configure a hard disk drive, make sure you have the configuration information supplied by the drive manufacturer. Incorrect settings may cause the system to fail to recognize the installed hard disk. To allow the BIOS to detect the drive type automatically, select [Auto].
IMPORTANT: If the hard disk was already formatted on an older system,Setup may detect incorrect parameters. You will need to enter the correct parameters manually, or use low-level format in case you do not need the data stored on the hard disk. If the parameters listed differ from the ones used when the disk was formatted, the disk will not be readable. If the auto-detected parameters do not match the ones that should be used for the disk, you should enter the correct ones manually by setting [User Type HDD]. [User Type HDD]

4. BIOS SETUP Chip Configuration
Read Around Write [Enabled] Setting this field to [Enabled] allows the memory controller to store write data in its buffer whenever the CPU issues a write command. The next time the CPU needs the data, it retrieves the data from the memory buffer without accessing the SDRAM. Configuration options: [Disabled] [Enabled] CPU-DRAM Back-Back Transaction [Enabled] Configuration options: [Enabled] [Disabled] Delayed Transaction [Disabled] When set to [Enabled], this feature frees the PCI bus when the CPU is accessing 8-bit ISA cards. This process normally consumes about 50-60 PCI Clocks without PCI delayed transaction. Set this field to [Disabled] when using ISA cards that are not PCI 2.1 compliant. Configuration options: [Enabled] [Disabled] PCI to DRAM Prefetch [Disabled] Configuration options: [Disabled] [Enabled] Byte Merge [Disabled] To optimize the data transfer on PCI, this feature combines a sequence of individual memory writes (bytes or words) into a single 32-bit block of data. However, byte merging may only be done when the bytes within a data phase are in a prefetchable address range. Configuration options: [Disabled] [Enabled] DRAM Read Latch Delay [1 ns] Configuration options: [0.0 ns] [0.5 ns] [1.0 ns] [1.5 ns] AGP Capability [4X Mode] This motherboard supports the AGP 4x interface that transfers video data at 1066MB/s. AGP 4x is backward-compatible, so you may leave the default [4X Mode] on even if you are using an AGP 1x or 2x video card. When set to [1X Mode], the AGP interface only provides a peak data throughput of 266MB/s even if you are using an AGP 2x/4x card. When set to [2X Mode], the AGP interface only provides a peak data throughput of 533MB/s even if you are using an AGP 4x card. Configuration options: [1X Mode] [2X Mode] [4X Mode] Graphics Aperture Size [64MB] This feature allows you to select the size of mapped memory for AGP graphic data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB] [128MB] [256MB]
Video Memory Cache Mode [UC] USWC (uncacheable, speculative write combining) is a new cache technology for the video memory of the processor. It can greatly improve the display speed by caching the display data. You must set this to UC (uncacheable) if your display card does not support this feature, otherwise the system may not boot. Configuration options: [UC] [USWC] Onboard PCI IDE Enable [Both] This field allows tou to enable either the primary IDE channel or secondary IDE channel, or both. You can also set both channels to [Disabled]. Configuration options: [Both] [Primary] [Secondary] [Disabled] Memory Hole At 15M-16M [Disabled] This field allows you to reserve an address space for ISA expansion cards. Setting the address space to a particular setting makes that memory space unavailable to other system components. Expansion cards can only access memory up to 16MB. Configuration options: [Disabled] [Enabled]

PCI DMA Resource Exclusion
DMA x Used By ISA [No/ICU] These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) ISA card. The setting [No/ICU] for a DMA channel indicates that you are using the ISA Configuration Utility (ICU), and that this particular DMA channel is NOT required by a legacy ISA card. Set the DMA field to [Yes] if you install a legacy ISA card that requires a DMA channel and you are NOT using ICU. Configuration options: [No/ICU] [Yes]
PCI UMB Resource Exclusion
ISA MEM Block BASE [No/ICU] This field allows you to set the base address and block size of a legacy ISA card that uses a memory segment within the C800 and DFFF address range. If you have such a card and you are not using ICU to specify its address range, select a base address from the six available options. When you select an option other than [No/ICU], the ISA MEM Block SIZE field appears for selecting the block size. If there is more than one legacy ISA card in the system that requires the use of this address range, you can increase the block size to 8K, 16K, 32K, or 64K. If you are using ICU to accomplish this task, leave ISA MEM Block BASE to its default setting [No/ICU]. Configuration options: [No/ICU] [C800] [CC00] [D000] [D400] [D800] [DC00]
4.4.4 Shadow Configuration
Video ROM BIOS Shadow [Enabled] When enabled, this field allows you to change the video BIOS location from ROM to RAM. Relocating the video BIOS to RAM enhances system performance because information access is faster than in ROM. Configuration options: [Disabled] [Enabled] C8000-DFFFF Shadow [Disabled] These fields are used for shadowing other expansion card ROMs. If you install any expansion card with a built-in ROM, you need to know which addresses the ROM uses to specifically shadow them. Shadowing a ROM reduces the memory available between 640K and 1024K by the amount used for this purpose. Configuration options: [Disabled] [Enabled]
4. BIOS SETUP Shadow Configuration

4.5 Power Menu

The Power menu allows you to reduce power consumption. This feature turns off the video display and shuts down the hard disk after a period of inactivity.
Power Management [User Defined] This field must be enabled to activate the automatic power saving features. When set to [Disabled], the power management features do not function regardless of the other settings on this menu. The [User Defined] option allows you to make your own selections in the Power menu. When set to [Max Saving], system power conserved to its greatest amount. The Suspend Mode field is then be set to a predefined value that ensures maximum power savings. This field acts as the master control for the power management modes. [Max Saving] puts the system into power saving mode after a brief period of system inactivity. [Min Saving] is almost the same as [Max Saving] except that the system inactivity period is longer. [Disabled] deactivates the power saving features, [User Defined] allows you to set power saving options according to your preference. Configuration options: [User Defined] [Disabled] [Min Saving] [Max Saving] IMPORTANT: You should install the Advanced Power Management (APM) utility to keep the system time updated even when the computer enters suspend mode. In DOS environment, you need to add the statement, DEVICE=C:\DOS\POWER.EXE, to the CONFIG.SYS file. In Windows 3.x and Windows 95, you need to install Windows with the APM feature. In Windows 98 or later, APM is automatically installed as indicated by a battery and power cord icon labeled Power Management in the Control Panel. Select the item Advanced in the Power Management Properties dialog box. 72 ASUS CUV4X-DLS Users Manual
