Chapter 3 Hardware Description
3.1 Processor
The AI5TV is designed to take a Pentium/Pentium MMX processor
with a bus speed of 50, 60 and 66MHz. Since the internal clock of the
CPU can be multiples of 1.5, 2, 2.5, 3 or 3.5 of the bus clock, the CPU
frequency can be 75MHz to 233MHz.
3.2 L2 Cache
The AI5TV supports 512K Pipelined Burst Synchronous Cache. The
P.B. Synchronous Cache boosts the system performance 10% higher
than regular Asynchronous Cache.
3.3 Main Memory
The AI5TV provides two 64-bit memory banks for up to 128MB. Each
bank consists of two SIMM sockets, SIMM1/SIMM2 and
SIMM3/SIMM4. Both EDO and page mode DRAMs are supported.
The size of the SIMMs can be 4MB, 8MB, 16MB and 32MB.
Each 64-bit memory bank can also be populated by using a DIMM
(Dual In-line Memory Module). The DIMM size can be 8MB, 16MB,
and 32MB. The DIMM types can be FPM, EDO or SDRAM
(synchronous DRAM). Since SIMMs are not available in SDRAM,
DIMMs must be used for SDRAM support.
The following are to be noted in populating SIMM and DIMM sockets:
1. Either SIMM1/SIMM2 or SIMM3/SIMM4 bank can be populated
first. The same is true with DIMM2 and DIMM1.
2. Each bank should consist of the same size of SIMMs.
3. Each bank should consist of the same type of SIMMs. For example,
SIMM1 and SIMM2 are both EDO or page mode.
4. SIMMs can be mixed by the bank. For example, SIMM1/SIMM2
are page mode and SIMM3/SIMM4 are EDO.
5. If SIMM1/SIMM2 or SIMM3/SIMM4 are occupied, then DIMM2
or DIMM1cannot be populated. The reverse is also true.

3.4 BIOS
The Award BIOS on the AI5TV system board provides the standard
BIOS functions plus the following additional features:
1. ISA Plug and Play (PnP) extension
Unlike PCI cards which are plug and play, ISA cards require
setting jumpers to resolve hardware conflict. To make a
computer system PnP, an ISA PnP standard is established and
supported by new OSes, such as Windows 95. Under
Windows 95, the system board BIOS must have ISA PnP
extension to support the new ISA PnP cards.
AI5TV Pentium PCI Baby AT Motherboard User’s Manual

Chapter 3 Hardware Description
2. 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. NCR 53C810 SCSI BIOS
NCR 53C810 is a PCI SCSI shipped from NCR. The BIOS
required to run cards with the 53C810 chip is built-in the
system BIOS. The BIOS will automatically detect the
existence of a 53C810 chip and configure it accordingly.
3.5 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
address which also becomes the identity of the device. There are a total
of 1K port address space available. The following table lists the I/O
port address used on the system board.

Chapter 6 BIOS User Guide
6.1 BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports Intel,
Cyrix, and AMD processors in a standard IBM-AT compatible I/O system. The Award 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 provides a Setup utility program for specifying the system configurations and settings. 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 will allow you to enter the Setup utility. If you
are a little bit late pressing the <Del> key, 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 <Ctrl>, <Alt> and <Del> 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> and <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.

The section below the setup items of the Main Menu displays the control keys for this menu. Another
section at the bottom of the Main Menu, just below the control keys section, displays information on the
currently highlighted item in the list.
NOTE: After making and saving system changes with Setup, you find
that your computer cannot boot. 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 if you
change your system hardware configurations, the onboard battery fails, or the configuration stored in the
CMOS memory was lost or damaged.

memory.
DRAM RAS# Recharge Time
DRAM must continuously be refreshed or it will loose its data. This option allows you to determine the
number of CPU clocks allocated for Row Address Strobe to accumulate its charge before DRAM is
refreshed. If refreshed time is not enough, refresh may be incomplete and data will be lost.
DRAM R/W Leadoff Timing
This field allows you to set the number of CPU clocks before reads and writes to DRAM. By default, it is
set to 7/6 Leadoff timing.
40
AI5TV Pentium PCI Baby AT Motherboard User’s Manual

Power Management
This field allows you to select what type of power saving management modes. There are fours selections
for Power Management.
Disable
No power management. (default)
Min. Power Saving
Minimum power management.
Max. Power Saving
Maximum power management. Only available for SL CPU.
User Define
Each of the ranges are from 1 min. to 1hr. Except for HDD Power Down
which ranges from 1 min. to 15 min.
PM Control by APM
This field allows you to use Advanced Power Management device to enhance the Max. Power Saving mode

Video OFF Method
This field defines the video off features. There are three options available:
V/H SYNC + Blank
Default setting, blank the screen and turn off vertical and horizontal scanning.
DPMS
Allows the BIOS to control the video display card if it supports the DPMS
feature.
Blank Screen
This option only writes blanks to the video buffer.
Doze Mode
When enabled, and after the set time of system inactivity, the CPU clock will run at a slower speed while
all other devices still operate at full speed.
Standby Mode
When enabled, and after the set time of system inactivity, the fixed disk drive and the video would be shut
off while all other devices still operate at full speed.
Suspend Mode
When enabled, and after the set time of system inactivity, all devices except the CPU will be shut off.
HDD Power Down
When enabled, and after the set time of system inactivity, the hard disk drive will be powered down while
all other devices remain active.
Wake Up Events In Doze & Standby
This 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.
Power Down & Resume Events
I/O events can either prevent the system from entering power saving mode or can awaken the system from
such a mode. When an I/O device wants to gain the attention of the operating system, it signals 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 as On, activity will neither prevent the system
from going into a power management mode, nor awaken it.

IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to transfer data to and from your hard
disk drive.
IDE Primary Master/Slave PIO And Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster. Rather than have the BIOS issue a series
of commands that transfer to or from the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly. This way will make work more efficiently.
The system supports five modes, numbered from 0 (default) to 4, which primarily differ in timing. When
Auto is selected, the BIOS will select the best available mode.
