Chapter 2 Specifications

Based on VIA’s VP3AT chipset, the AI5VG is a Baby AT Pentium

motherboard that supports all the features to make a Microsoft PC’97

compliant PCI/ISA system. This high performance model comes with

an Accelerated Graphics Port (AGP) slot, power management

functionalitythat is compliant with ACPI (Advanced Configuration and

Power Interface) and legacyAPM requirements. In addition to standard

PIO and DMA mode operation, the AI5VG features Ultra DMA/33 for

improved disk I/O throughput. The main features of this motherboard

are listed as follows:

Main Processor

Intel Pentium 90/100/120/133/150/166/200

Intel Pentium MMX (P55C) 90/100/120/133/150/166/200/233

Cyrix 6x86/6x86L P150+/P166+/P200+

Cyrix 6x86MX PR166/PR200/PR233/PR266

AMD K5 PR100/PR133/PR166

AMD K6 166/200/233

L2 Cache

512KB Pipelined Burst Synchronous SRAM onboard

Main Memory

Four 72-pin SIMM sockets and two 168-pin DIMM sockets

Memory Type

SIMMs: FPM (Fast Page Mode) or EDO (Extended Data Out)

SIMM Size: 4MB 8MB 16MB 32MB 64MB

DIMMs: EDO DRAM or SDRAM (Synchronous DRAM)

DIMM Size: 8MB 16MB 32MB 64MB 128MB

Chipset

VIA’s VP3AT chipset with built-in PCI EIDE

Onboard I/O

Winbond W83877 for two serial, one parallel, one floppy drive

interface and IrDA support

Chapter 2 Specifications

AI5VG Pentium VP3 Baby AT Motherboard User’s Manual 3

Onboard Bus Mastering EIDE

Two EIDE interfaces for up to four devices, support PIO Mode 3/4

or Ultra DMA/33 IDE Hard Disk and ATAPI CD-ROM.

BIOS

Licensed BIOS with additional features:

• FLASH EEPROM (128KB) for BIOS update

• ISA Plug and Play (PnP) extension

• Power management

CPU Temperature Sensor

The AD22105 ICon the motherboard is a temperature sensor for the

CPU. When the CPU temperature exceeds threshold value, the CPU

slows down automatically to allow it to cool down to a safe level.

Windows 95 Shut-Down

This allows the PC to power off via Windows 95 operating system.

(This feature requires ATX power supply.)

AGP Support (Accelerated Graphics Port)

The AI5VG motherboard comeswithan AGP slot for an AGP VGA

card that supports 133MHz 2X mode for AD and SBA signaling.

PC97 Compliance

The AI5VG implements BIOS and hardware designs that meet

PC97 standards and is fully compatible with all Windows operating

systems.

Expansion Slots

Four 32-bit PCI slots

Two 16-bit ISA slots

One AGP slot

Form Factor

Baby AT, 9”x8.6” (23cm x 22cm)

Chapter 3 Hardware Description

6 AI5VG Pentium VP3 Baby AT Motherboard User’s Manual

3.1 Processor and CPU Voltage

The AI5VG is designed to take a Pentium Processor with a bus speed of

60 and 66 MHz. The internal clock of the CPU can be multiples of 1.5, 2,

2.5, 3, 3.5, 4 and 4.5 of the bus clock, the CPU frequency can be 90 to

300MHz.

The onboard CPU voltage regulator provides support for CPUs Vcore

which require voltage other than 3.3V such as 2.8V, and/or power

consumption higher than 10 watts.

3.2 L2 Cache Memory

The AI5VG supports 512KB P.B. (Pipelined Burst) Synchronous Cache.

The P.B. Synchronous Cache boosts the system’s performance, 10%

higher than regular Asynchronous Cache.

3.3 Main Memory

The AI5VG motherboard supports four 72-pin SIMMs and two 168-pin

DIMMs (Dual In-line Memory Module) sockets. The DRAMs for the

SIMM socketscan be 4MB, 8MB, 16MB, 32MB, and 64MB in EDO and

FPM types. DIMM modules can be 8MB, 16MB, 32MB, 64MB and

128MB in EDO DRAM or SDRAM type.

The following should be noted when populating the SIMM/DIMM

sockets:

1. SIMM1/SIMM2, SIMM3/SIMM4 or DIMM1, DIMM2 bank can be

populated first.

2. Each bank**should consist of the same size SIMMs.

3. Each bank should consist of the same type SIMMs. For example,

SIMM1 and SIMM2 are both be EDO or Page Mode.

** Each bank consists of two SIMM slots or one DIMM slot. For

example, SIMM 1 and SIMM 2 are considered as one bank and

DIMM 1 as another one.
