This chapter briefly describes each of the major features of the TI5VGA
motherboard. The layout of the board is shown in Figure 1 which shows
the locations of the key components. The topics covered in this chapter
are as follows:
3.1 Processor and CPU Voltage........................................................7
The TI5VGA is designed to take a Socket 7-based processor with a bus
speed of 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, 4.5, 5 and 5.5 of the bus clock, the CPU
frequency can be 100 to 550MHz.
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 t han 10 watts.
3.2 L2 Cache Memory
The TI5VGA supports 1MB P.B. (Pipelin ed Burst) Sync h ron ou s C ach e.
2MB is optional. The P.B. Synchronous Cache boosts the system’s
performance, 10% higher than regular Asynchronous Cache.
3.3 Main Memory
The TI5VGA motherboard support s t h ree 168- pi n DIMMs (D u al In - li n e
Memory Module) sockets. DIMM modules can be 8MB, 16MB, 32MB,
64MB and 128MB in EDO DRAM or SDRAM type. DIMM1, DIMM2
or DIMM3 bank can be populated first. Examples are shown in the
following table on how to configure the memory size.
The BIOS on the TI5VGA motherboard provides the standard BIOS
functions plus the following additional features:
1. DMI (Desktop Management Interface)
The motherboard supports D MI to en abl e computer syst em management
in an enterprise.
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. Un der Window s 95, th e mot herboard BIOS mu st 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 VT82686A chipset. It supports
PIO mode 3/4 and bus ma stering . The peak tran sfer rate of PIO m ode 3/4
can be as hig h as 17MB/sec. Usin g HDDs that su pport bus m astering , 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 supported. The VT82686A also supports UDMA33
and UDMA66, a new “synchronous DMA” protocol for faster data
transfers.
3.6 Onboard Multi-I/O
The multi-I/O is integrated in the VIA chipset that 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.
The hardware monitoring function is integrated in the VIA chipset. It
monitors the system temperature, voltages and fan speeds. With the use
of a system management utility, the hardware status can be checked and
warning message can be displayed when there is a problem.
3.8 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
addresses 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
addresses used on the motherboard.

3.11 Accelerated Graphics Port (AGP) Slot
The TI5VGA motherboard comes with an AGP slot for an AGP VGA
card that supports 133MHz 2X mode for AD and SBA signaling to
provide high-performance 3D graphic display.
The TI5VGA-100MHz, on the other hand, supports VIA’s MVP3
chipset and has a maximum CPU bus speed of 100MHz. Please note the
correct settings of both the CPU and SDRAM clocks.
In the case your motherboard TI5VGA-100MHz has a processor
supporting 100MHz CPU clock (such as AMD K6-2/300) and your
DIMM module is PC100 compliant, the SDRAM clock can be set to
100MHz. Otherwise, set the SDRAM clock at 66MHz.

This chapter describes the different settings available in the Aw ard BIOS
that comes with the TI5VGA motherboard. The topics covered in this
chapter are as follows:
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 ration s an d s ettin g s. The BIOS ROM of th e 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 th e <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 e nt ries, <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.
“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
hardware configurations, the onboard battery fails, or the configuration
stored in the CMOS memory was lost or damaged.
