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.

Hardware Installation

3. HARDWARE INSTALLATION

3.1. UNPACKING

The main board package should contain the following:

• The 6ZM7/6ZM7A main board.

• USER'S MANUAL for main board.

• Cable set for IDE, Floppy devices.

• CD for main board Utility. (Bus Master + Sound Driver + LDCM + Utility)

The main board contains sensitive electric components, which can be easily
damaged by static electricity, so the main board 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 main board 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 main board 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.

3.4. DRAM INSTALLATION

The main board can be installed with 16 / 32 / 64 / 128 / 256 MB 168 pins DIMM
module DRAM, and the DRAM speed must be 50 or 60 ns for EDO & 67MHz for
SDRAM when system bus speed is set to 66MHz. The DRAM memory system
on main board consists of bank 0 and bank 1.
Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bits system. The total memory size is 16 MB ~ 256MB
SDRAM, EDO DRAM size is 16MB ~ 256MB. The DRAM installation position
refer to Figure 3.1, and notice the Pin 1 of DIMM module must match with the
Pin 1 of DIMM socket. Insert the DIMM module into the DIMM socket at Vertical
angle. If there is a wrong direction of Pin 1, the SDRAM DIMM module could
not be inserted into socket completely.

3.5. CPU SPEED SETUP

The system bus frequency can be switched between 66MHz and 133MHz by
adjusting DIP SW2. The CPU frequency ratio can be switched from X3 to X9.5
by adjusting DIP SW1. The user can set up CPU speed for 366~533MHz
processors by adjusting SW1 and SW2 properly.

M

Please set the CPU host frequency in accordance with your

processor’s specifications. We don’t recommend you to set the

system bus frequency over the CPU’s specification because these
specific bus frequencies are not the standard specifications for
CPU, chipset and most of the peripherals. Whether your system can
run under these specific bus frequencies properly will depend on
your hardware configurations, including CPU, Chipsets, SDRAM,
Cards….etc.

M

The CPU is a sensitive electric component and it can be easily

damaged by static electricity, so users must keep it away from metal
surface when the CPU is installed onto main board.

3.6. CMOS RTC & ISA CFG CMOS RAM

There're RTC & CMOS RAM on board; they have a power supply from external
battery to keep the DATA inviolate & effective. The RTC is a REAL-TIME
CLOCK device, which provides the DATE & TIME to system. The CMOS
SRAM is used for keeping the information of system configuration, so the
system can automatically boot OS every time. Since the lifetime of internal
battery is 5 years, the user can change a new Battery to replace old one after it
cannot work.

M Danger of explosion if battery is incorrectly replaced.
M Replace only with the same or equivalent type recommended by the

manufacturer.

3-7

6ZM7/6ZM7A

M Dispose of used batteries according to the manufacturer’ s instructions.

3.7. SPEAKER CONNECTOR INSTALLATION

There is a speaker in AT system for sound purpose. The 4 - Pins connector
SPKR is used to connect speaker. Pin2-3 short is internal speaker (Default
value).

3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION

The RESET switch on panel provides users with HARDWARE RESET function.
The system will do a cold start after the RESET switch is pushed and released
by user. The RESET switch is a 2 PIN connector and should be installed to

RST on main board.

3.9. POWER LED CONNECTOR INSTALLATION

System has power LED lamp on the panel of chassis. The power LED will light
on off or flash to indicate which step on the system. The connector should be
connected to P+P-P- of main board in a correct direction.

3.10. IDE & ATAPI DEVICE INSTALLATION

There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which following
ATAPI standard SPEC. Each IDE port can connected to two ATAPI devices
(IDE Hard Disk, CD-ROM or Tape Driver), so total four ATAPI devices can
exist in a system. The HD is the active LED port for ATAPI devices.

3.11. PERIPHERAL DEVICE INSTALLATION

After the I/O device installation and jumpers setup, the main board can be
mounted into the chassis and fixed by screw. To complete the main board
installation, the peripheral device could be installed now. The basic system
needs a display interface card. If the PCI - Bus device is to be installed in the
system, any one of three PCI - Bus slots can be used.

3.12. KEYBOARD & PS/2 MOUSE INSTALLATION

The main board supports PS/2 Mouse. The BIOS will auto detect whether the
PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is
installed. After installing the peripheral device, the user should check
everything again, and ready power-on the system.
