ACPI Ready (optional ) When you install a remote power supply, this mainboard fully implements the new ACPI (Advanced Configuration Power Interface) standard. ACPI enables PCs to come on instantly when accessed by a user and remain available to perform certain tasks even after the PC is turned off. Additional benefits of ACPI include improved thermal management, reduced energy consumption, and OS directed Plug and Play capabilities. VT-503 Mainboard Manual • Soft-Off Support The mainboard's Soft-Off feature allows you to turn off your computer using the Operating System (Windows® 95). The feature requires a power supply with a soft-off power controller. • Remote Ring-On The Remote Ring-On function allows your computer to be turned on remotely via a modem while it is in Sleep Mode. The Remote Ring-On function requires a power supply with a soft-off power controller. • RTC Alarm The RTC alarm feature allows you to implement a number of useful functions, such as automaticall y sending out a fax late at night. DMI (Desktop Managemen t Interface ) Enhanced system manageabilit y is becoming an increasingly important factor in reducing the total cost of ownership of systems, particularl y in a corporate environment. To provide this capability, this mainboard supports DMI at the BIOS level and includes a DMI Configuration Utility to maintain the Management Information Format Database. Chapter 2 Installatio n Procedure s The VT-503 has several user-adjustabl e jumpers on the board that allow you to configure your system to suit your requirements. To set up your computer, you should follow these installation steps: 1). set system jumpers; 2). install RAM modules; 3). install the CPU; 4). install expansion cards; 5). connect cables and power supply; 6). set up BIOS feature. CAUTION : If you use an electric drill to install this mainboard on your chassis, please wear a static wrist strap. The recommended electric drill torque is from 5.0 to 8.0 kg/cm to avoid damaging the chips' pins. Jumpers Jumpers are used to select the operation modes for your system. Some jumpers on the board have three metal pins with each pin representing a different function. To set a jumper, a black cap containing metal contacts is placed over the jumper pin/s according to the required configuration. A jumper is said to be shorted when the black cap has been placed on one or two of its pins. The types of jumpers used in this manual are shown below: 1 l ool 1Д [ 2 1 1 3 2 1 Jumper s are shown as above a- j ° o °l I stands for pin 1 |oo-e> l 3 2 1 1 Jumper cap is shown as above NOTE : Users are not encouraged to change the jumper settings not listed in this manual.

DIM1 and DIM2 only support 3.3V (unbuffered) EDO and SDRAM modules. 3. DIM1 and SIMM1&2 are shared, so are DIM2 and SIMM2. That is, it is not allowed to install RAM modules on DIM1 and SIMM1&2 at the same time. 4. The different size of DIM1 and DIM2 is allowed. For example, 16MB is installed on DIM1 socket, 32MB is installed on DIM2 socket. 5. It is recommended that SIMMs and DIMMs are not installed at the same time on this mainboard to avoid unexpected failure. 6. This mainboard supports DIMMs with latency times of 10ns and 12ns. EGC memory and parity check are not supported. 7. This mainboard supports SIMMs with latency times of 70ns and 60ns. ECC memory and parity check are not supported. Cache Memory The mainboard comes with onboard 512KB synchronous 3 V Pipeline Burst SRAMs. Cache memory access is very fast compared to main memory access. The cache holds data for imminent use. Since cache memory is from five to more than ten times faster than main memory, the CPU's access time is reduced, giving you better system performance. Pentium mainboards may implement various types of L2 cache SRAMs. Pipeline Burst SRAM is one of them, delivering the best price performance ratio. They perform much better than asynchronous SRAMs. NOTE: The cache memory can not be upgraded by end users. 11 VT-503 Mainboard Manual Installation Procedures 3). Install the CPU The CPU module resides in the Zero Insertion Force (ZIF) socket on the mainboard. CAUTION : 1. Always turn the system power off before installing or removing any device. 2.

Install Expansion Cards Your VT-503 features three 16-bit ISA Bus and four 32-bit PCI Bus expansion slots. This section describes how to connect an expansion card to one of your system's expansion slots. Expansion cards are printed circuit boards that, when connected to the mainboard, increase the capabilities of your system. For example, expansion cards can provide video and sound capabilities. CAUTION : 1. Always turn the system power off before installing or removing any device. 2. Always observe static electricity precautions. See "Handling Precautions" at the start of this manual. To install an expansion card, do the following: 3. Remove the chassis cover and select an empty expansion slot. Remove the corresponding slot cover from the chassis. Unscrew the mounting screw that secures the slot cover and pull the slot cover out from the chassis. Keep the slot cover mounting screw nearby. Holding the edge of the peripheral card, carefully align the edge connector with the expansion slot. Push the card firmly into the slot. Push down on one end of the expansion card, then the other. Use this "rocking" motion until the add-in card is firmly seated inside the slot. Secure the board with the mounting screw removed in Step 2. Make sure that the card has been placed evenly and completely into the expansion slot. 22 Installation Procedures 5).
