1.6. What is AGP ?
The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI
bridge device that supports an AGP port. 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 speed up the transaction.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The mainboard package should contain the following:
•The 6BNZ mainboard and RISER card (Optional).
•Universal Retention Mechanism & Attach Mount
•USER'S MANUAL for mainboard.
•Cable set for IDE¡BFloppy and Joystick (Optional).
•Diskette or CD for Mainboard¡BVGA¡BSound and LAN Utility
(Optional).
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 damages 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.
