Chapter 2 Hardware Description
2.1 Processor
The AI5TV is designed to take a Pentium processor with a bus speed of 50, 60 and 66 MHz. Since the internal clock of the CPU can be multiples of 1.5, 2, 2.5 or 3 of the bus clock, the CPU frequency can be 75MHz to 200MHz.
2.2 L2 Cache and Cache Module Connector
The AI5TV supports Pipelined Burst Synchronous Cache 256K or 512K. The P.B. Synchronous Cache boost the system performance 10% higher than regular Asynchronous Cache.
Chapter 2 Hardware Description
6 AI5TV Motherboard User’s Manual
2.3 Main Memory
The AI5TV provides two 64-bit memory banks for up to 128MB. Each bank consist of two SIMM sockets, M0/M1 and M2/M3. Both EDO and page mode DRAMs are supported. The size of the SIMMs can be 4MB, 8MB, 16MB or 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, 32MB or 64MB. 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 the important factors for populating the SIMM sockets:
1. Either M0/M1 or M2/M3 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.
ex: M0 and M1 should both be EDO or page mode.
4. SIMMs can be mixed by the bank.
ex: M0/M1 are page mode and M2/M3 are EDO
5. If M2/M3 are occupied, then M5 can not be populated. The reverse is also true.
Bank0(M0, M1) Bank1(M2, M3) Total Memory
4MB ----- 8MB
8MB ----- 16MB 16MB ----- 32MB 32MB ----- 64MB

2.4 BIOS
The 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.
2. Power management
The power management feature provides power saving by slowing down the CPU clock, turning off the monitor screen, and stopping the HDD spindle motor.
3. NCR 53C810(AHA7850) SCSI BIOS
NCR 53C810(AHA7850) is a PCI SCSI shipped from NCR (Adaptec). The BIOS required to run cards with the 53C810(AHA7850) chip is built-in the system BIOS. The BIOS will automatically detect the existence of an 53C810 (AHA7850) chip and configure it accordingly.

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.
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 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> 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.

NOTE: After making and saving system changes with Setup, you find
that your computer can not 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.
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 change your system hardware configurations, the onboard battery fails, or the configurations stored in the CMOS memory were lost or damaged.

Chapter 5 BIOS
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the system registers repeated keystrokes speed. You can select speed range from 6 to 30 characters per second. By default, this item is set to 6.
Typematic Delay (Msec)
When the typematic rate is enabled, this item allows you to set the time interval for displaying the first and second characters. By default, this item is set to 250msec.
Security Option
This field allows you to limit access to the System and Setup. The default value is Setup. When you select System, the system prompts for the User Password every time you boot up. When you select Setup, the system always boots up and prompts for the Supervisor Password only when the Setup utility is called up.
PCI/VGA Palette Snoop
Some display cards that are non-standard VGA may not show colors properly. This field allows you to set whether MPEG ISA/VESA VGA Cards can work with PCI/VGA or not. When this field is enabled, a PCI/VGA can work with a MPEG ISA/VESA VGA card. When this field is disabled, a PCI/VGA cannot work with a MPEG ISA/VESA Card.
OS Select for DRAM > 64
This option allows the system to access greater than 64MB of DRAM memory when used with OS/2 which depends on certain BIOS calls to access memory. The default setting is NON-OS/2.
Video BIOS Shadow
This item allows you to change the Video BIOS location from ROM to RAM. Video Shadow will increase the video speed.
C8000 - CBFFF Shadow/DC000 - DFFFF Shadow
Shadowing a ROM reduces the memory available between 640KB to 1024KB. These fields determine whether optional ROM will be copied to RAM or not.

Auto Configuration
This field predefined values for DRAM, cache timing according to CPU type and system clock. When this field is enabled, the predefined items will become read-only.
DRAM Timing
The DRAM timing is controlled by the DRAM Timing Registers. The timing type is dependent on the system design. Slower rates may be required in some system designs to support loose layouts or slower 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.
Chapter 5 BIOS
Fast RAS to CAS Delay
When DRAM is refreshed, both rows and columns are addressed separately. This field allows you to determine the timing of transition from Row Address Strobe (RAS) to Column Address Strobe (CAS). By default, it is set to 3 CPU clocks.
Refresh RAS# Assertion
This field allows you to determine the number of CPU clocks asserted for the Row Address Strobe is refreshed. By default, it is set to 5
CLKS.
ISA Bus Clock
This field allows you to select the PCI clock type.
Pipeline Cache Timing
This field allows you to select two timings of pipeline caches, Faster and Fastest.
System BIOS Cacheable
When enabled, accesses to the system BIOS ROM addressed at F0000H-FFFFFH are cached, provided that the cache controller is enabled.
Video BIOS Cacheable
When enabled, accesses to the video BIOS addressed at C0000H to C7FFFH are cached, provided that the cache controller is enabled.
8 Bit I/O Recovery Time
This field allows you to select the recovery time allowed for 8 bit I/O. By default, this field is set to 1 Clock.
16 Bit I/O Recovery Time
This field allows you to select the recovery time allowed for 16 bit I/O. By default, this field is set to 1 Clock.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA cards. This field allows you to reserve 15MB to 16MB memory address space to ISA expansion cards. This makes memory from 15MB and up unavailable to the system. Expansion cards can only access memory up to 16MB. By default, this field is set to
Disabled.
Peer Concurrency
This field allows you to select the number of PCI devices to be activated at a time. The default value is Enabled.

Chapter 5 BIOS
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 slower speed while all other devices still operate at full speed.
Standby Mode
When enabled and after the set time of system inactivity expires, 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 expires, 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 suspend mode.
Power Down & Resume Events
This section are I/O events which can prevent the system from entering a 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 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 to 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 controller and CPU directly. This way will make the 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.
