G486VPC Rev. BA0+ System Board User’s Manual - 30061018 - FCC Statement on Class B This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful in- terference when the equipment is operated in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular in- stallation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and the receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio TV technician for help. Notice: 1. The changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to oper- ate the equipment. 2. Shielded interface cables must be used in order to comply with the emission limits.

The G486VPC system board is equipped with a 237-pin Zero Insertion Force (ZIF) CPU socket that allows users to easily upgrade their pro- cessor with Intel, AMD, Cyrix or SGS-Thomson CPUs. The G486VPC system board uses Award BIOS (Windows 95 Plug and Play compatible) that supports Enhanced IDE HDDs larger than 528MB. The G486VPC can support 1MB to 64MB of system memory using x32 or x36 DRAM. It also supports 128KB or 256KB Level 1 and Level 2 write-back/write-through cache. Equipped with one built-in VL-bus IDE connector and one ISA IDE con- nector, the G486VPC system board can control four drives and sup- ports fast Mode 3 and Mode 4 HDDs. This system board is also equipped with two NS16C550A-compatible serial ports, an ECP/EPP parallel port, a floppy disk drive controller, one PS/2 mouse port and one AT or optional PS/2 keyboard connector. The G486VPC design is based on the Peripheral Component Intercon- nect (PCI) local bus and Industry Standard Architecture (ISA) stan- dards. It is equipped with 6 dedicated ISA slots, and 1 shared PCI/8-bit ISA slot. 5 Features and Specifications Processor • 5V CPUs - Intel, Cyrix and SGS-Thomson • 3.3V CPUs - Intel, AMD, Cyrix and SGS-Thomson Chipset • VIA VT82C496 - system and cache controller • VIA VT82C505 - PCI bridge • VIA VT82C416 - peripheral chip Cache Memory • 128KB or 256KB • Supports Level 1 and Level 2 write-back/write-through cache System Memory • 1MB to 128MB • Three 72-pin SIMM sockets • Supports memory parity-check function • 256KBx36/x32, 1MBx36/x32, 4MBx36/x32, and 16MBx36/x32 (SM1- SM3) • 512KBx36/x32, 2MBx36/x32, and 8MBx36/x32 (SM1 or SM3) BIOS • Award BIOS, Windows 95 Plug and Play compatible (Flash EPROM or EPROM) • Supports Enhanced IDE HDDs larger than 528MB • System and EGA/VGA BIOS shadow Energy Efficient Design • Supports SMM mode and CPU stopped clock • Hardware supports flexible event-driven power management scheme and easy CPU state transition: Ready, Doze and Suspend • Microsoft APM 1.1 compliant • EPA Energy Star compliant design 6 Integrated I/O • Uses UMC super I/O controller • Two NS16C550A-compatible enhanced serial ports • One ECP/EPP parallel port • Supports 360KB, 720KB, 1.2MB, 1.44MB, and 2.88MB floppy drives • Two fast IDE connectors: - Primary IDE is a VL-Bus IDE to support Mode 3 and Mode 4 HDDs - Secondary IDE is an ISA IDE to support one tape drive and one ATAPI CD-ROM drive ZIF Socket • 237-pin ZIF socket (Intel Socket 3) Connectors • 2 serial ports • 1 parallel port • 2 IDE connectors • 1 floppy connector • 1 PS/2 mouse port • 1 AT keyboard connector or optional mini-DIN-6 PS/2 keyboard port Expansion Slots • 6 dedicated 16-bit ISA slots • 1 shared PCI/8-bit ISA slot PCB • Four layers, Baby AT form factor • 25cm (9.84") x 22cm (8.66")
