Introduction

1.5. INTRODUCE THE PCI - BUS
Connecting devices to a CPU local bus can dramatically increase the speed of I/O-
bound peripherals with only a slight increase in cost over traditional systems.
This price / Performance point has created a vast market potential for local bus
products.
The main barrier to this market has been the lack of an accepted standard for local
bus peripherals.
Many mainboard and chipset manufactures developed their own local bus
implementations, but they are incompatible with each other.
The VL (Video Electronics Standards Association) local bus and PCI (Peripheral
Component Interconnect) bus specification was created to end this confusion.
The PCI - bus standard, under development since Jun. 1992, which is designed to
bring workstation-level performance to standard PC platform. The PCI - bus
removes many of the bottlenecks that have hampered PC for several years.
On the PCI - bus, peripherals operate at the native speed of the computer system,
thus enabling data transfer between peripherals and the system at maximum speed.
This performance is critical for bandwidth-constrained devices such as video,
multimedia, mass storage, and networking adapters.
PCI - bus standard provides end-users with a low-cost, extendible and portable local
bus design, which will allow system and peripherals from different manufactures to
work together.
1.6. FEATURES
q32 bits bus transfer mode.
qBus Master or Slave access.
qMemory burst transfer to 132 MB/sec.
q33 MHz operation speed.
q10 device loading ability.
qCPU independent.

1.7. What is AGP
The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI bridge
device that supports graphics display interface. The main purpose of the AGP port
is to provide fast access to system memory.
The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32-bits at
33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side
band addressing. When the 2x-data rate is used the port can transmit data at
533Mb/sec (66.6*2*4). The read-queue can be used to pipeline reads –removing the
effects of the reads-latency. Side band addressing can be used to transmit the data
address on a separate line in order to further speed the transaction.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The mainboard package should contain the following:
•The 5AA mainboard.
•USER’S MANUAL for mainboard.
•Cable set for IDE ¡B Floppy ¡B I/O Port & PS/2 mouse (Optional).
•CD for Mainboard Drivers and Utilities.
The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original packing
until it is installed.
Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the same point
as the anti-static mat.
Inspect the mainboard carton for obvious damage. Shipping and handling may
cause damage to your board. Be sure there are no shipping and handling damage
on the board before proceeding.
After opening the mainboard carton, extract the system board and place it only on a
grounded anti-static surface component side up. Again inspect the board for
damage.
Press down on all of the socket IC’s to make sure that they are properly seated. Do
this only on with the board placed on a firm flat surface.
M DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED.
It is assumed that the chassis is designed for a standard AT mainboard mounting.
Place the chassis on the anti-static mat and remove the cover.
Take the plastic clips, Nylon stand-off and screws for mounting the system board,
and keep them separate.
