AI5VG+ User’s Manual 7
3.1 Processor and CPU Voltage
The AI5VG+ is designed to take a Pentium Processor with a bus speed of
60, 66, 75, 83 and 100 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 r egular Asynchronous Cache.
3.3 Main Memory
The AI5VG+ motherboard supports two 72-pin SIMMs and three
168-pin DIMMs (Dual In-line Memory Module) sockets. The DRAMs
for the SIMM sockets can 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. Each bank**
should consist of the same size SIMMs.
2. Each bank should consist of the same type SIMMs. For example,
SIMM1 and SIMM2 are both be EDO or Page Mode.
3. 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.

3.4 BIOS
The BIOS on the AI5VG+ motherboard provides the standard BIOS
functions plus the following additional features:
1. DMI (Desktop Management Interface)
The motherboard supports DMI t o en able computer system management
in an enterprise.
Chapter 3 Hardware Description
10 AI5VG+ User’s Manual
2. ISA Plug and Play (PnP) Extension
Unlike PCI cards which are plug and play, ISA cards require setting
jumpers to resolve hardware conflicts. To make a computer system PnP,
an ISA PnP standard is established and supported by new OSes, such as
Windows 95. Under Wi ndow s 95, th e moth erboard BIOS mus t have ISA
PnP extension to support the new ISA PnP cards.
3. Power Management
The power management feature provides power savings by slowing down
the CPU clock, turning off the monitor screen and stopping the HDD
spindle motor.
3.5 Onboard PCI EIDE
The PCI EIDE controller is part of the MVP3 chipset. It supports PIO
mode 3/4 and bus m asterin g . The peak tran sfer rate of PIO m ode 3/4 can
be as high as 17MB/sec. Using HDDs that support bus mastering, the
peak transfer rate can reach 22MB/sec. There are two IDE connectors,
primary IDE and secondary IDE. With two devices per connector, up to
four IDE drives are s upporte d. The MVP3 also su pports Ultra DMA /33,
a new “synchronous DMA” protocol for faster data transfers.
3.6 Onboard Multi-I/O
The onboard multi-I/O chip, Winbond W83877, supports two 16550
UART-compatible serial ports, one high speed EPP/ECP parallel port
and one floppy controller. The floppy controller supports 2.88MB
format. The I/O port addresses of the serial and parallel ports are
programmable via BIOS set-up.
3.7 Onboard CPU Temperature Sensor
The AD22105 IC on 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.
Chapter 3 Hardware Description
AI5VG+ User’s Manual 11

5.2 J8: AT Power Supply Connector
When using an AT compatible power supply, plug both of the power
supply connectors into J8. Make sure the power supply connectors are
connected in the right orientation. The power supply connectors are
connected in the right orientation if the black wires of each power cable
are ADJACENT to each other. That is, black wires of each connector
should be aligned in the center of the J8 power supply connector.

6.1 BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel/Cyrix/AMD processors in a
standard IBM-AT compatible I/O system. The BIOS provides critical
low-level support for standard devices such as disk drives, serial and
parallel ports. It also adds virus and password protection as well as
special support for detailed fine-tuning of the chipset controlling the
entire system.
6.2 BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system conf ig u rations an d s etting s . The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you
to enter the Setup utility. If you are a little bit late pressing the <Del> k ey,
POST(Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> a nd <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

NOTE: After making and saving system changes with Setup, you find
that your computer cannot boot, the Award BIOS supports an
override to the CMOS settings that resets your system to its
default.
We strongly recommend that you avoid making any changes to
the chipset defaults. These defaults have been carefully chosen
by both Award and your system manufacturer to provide the
absolute maximum performance and reliability.

6.3 Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system and set the system
clock and error handling. If the motherboard is already installed in a
working system , you will not need to select this option. You will need to
run the Standard CMOS option, however, if you cha nge your system

stored in the CMOS memory was lost or damaged.

Primary HDDs / Secondary HDDs
The onboard PCI IDE connectors provide Primary and Secondary
channels for co nnecting up to four IDE hard disks or other IDE devices.
Each channel can support up to two hard disks; the first is the “Master”
and the second is the “Slave”.
To enter the specifications for a hard disk drive, you must select first a
“Type”. There are 45 predefin ed types and 4 user definable types are for
Enhanced IDE BIOS. Type 1 to 45 are predefined. Type “User” is
user-definable. For the Primary Master/Slave as well as Secondary
Master/Slave, you can select “Auto” under the TYPE and MODE fields.
This will enable auto detection of your IDE drives and CD-ROM drive
during POST.
Press <PgUp>/<PgDn> to select a numbered hard disk type or type the
number and press the <Enter> key. The hard disk will not work properly
if you enter incorrect informatio n for this field. If your hard disk drive
type is not matched or listed, you can use Type User to define your own
drive type manually . If y ou select Type User, related information is asked

PM Events
The VGA, LPT & COM, HDD & FDD, DMA /master, Modem Ring
Resume, RTC Alarm Resume and Primary INTR section are I/O events
which can prevent the system from entering a power saving mode or can
awaken the sy s tem from such a mode. When an I/O device wants to gain
the attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service. The default value is
Off
. When
set On, activity will neither prevent the system from going into a power
management mode nor awaken it. The IRQ section sets the wake-up call
of the system. If activity is detected from any enabled IRQ channels in the
left-hand group, the system wakes up from suspended mode.
