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 Window Size [32MB] 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]
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] 66 ASUS CUV4X-D Users Manual
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.
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 Define] [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. ASUS CUV4X-D Users Manual 67
4. BIOS SETUP Shadow Configuration
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.
Video Off Option [Suspend -> Off ] This field determines when to activate the video off feature for monitor power management. Configuration options: [Always On] [Suspend -> Off] Video Off Method [DPMS OFF] This field defines the video off features. The DPMS (Display Power Management System) feature allows the BIOS to control the video display card if it supports the DPMS feature. [Blank Screen] only blanks the screen (use this for monitors without power management or green features. If set up in your system, your screen saver will not display with [Blank Screen] selected). [V/H SYNC+Blank] blanks the screen and turns off vertical and horizontal scanning. Configuration options: [Blank Screen] [V/H SYNC+Blank] [DPMS Standby] [DPMS Suspend] [DPMS OFF] [DPMS Reduce ON] HDD Power Down [Disabled] Shuts down any IDE hard disk drives in the system after a period of inactivity as set in this user-configurable field. This feature does not affect SCSI hard drives. Configuration options: [Disabled] [1 Min] [2 Min] [3 Min].[15 Min] Suspend Mode [Disabled] Sets the time period before the system goes into suspend mode. Configuration options: [Disabled] [30 Sec] [1 Min] [2 Min].[1 Hour] PWR Button < 4 Secs [Soft Off] When set to [Soft off], the ATX switch can be used as a normal system power-off button when pressed for less than 4 seconds. [Suspend] allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. Regardless of the setting, holding the ATX switch for more than 4 seconds will power off the system. Configuration options: [Soft off] [Suspend]

4.5.1 Power Up Control
PWR Up On External Modem Act [Disabled] This allows either settings of [Enabled] or [Disabled] for powering up the computer when the external modem receives a call while the computer is in Soft-off mode. NOTE: The computer cannot receive or transmit data until the computer and applications are fully running. Thus connection cannot be made on the first try. Turning an external modem off and then back on while the computer is off causes an initialization string that will also cause the system to power on. Configuration options: [Disabled] [Enabled] Wake On LAN or PCI Modem [Enabled] Wake-On-LAN/PCI Modem allows your computer to be booted from another computer via a network by sending a wake-up frame or signal. Configuration options: [Disabled] [Enabled] IMPORTANT: This feature requires an optional network interface with Wake-OnLAN and an ATX power supply with at least 720mA +5V standby power.
