Introduction to VL-Bus
The Series 87 Enterprise-IV EISA Local Bus Motherboard conforms to the VESA® (Video Electronics
Standards Association) VL-Bus® specifications as well as the EISA (Extended Industry Standard
Architecture) specification.
The VL-Bus
The VL-Bus is designed to standardize the hardware interface of peripherals connected to a
microprocessor-level local bus. The VL-Bus Specification is a standard set of interface, architecture,
timings, electrical, and physical specifications that permits all VL-Bus products to be totally
interchangeable.
VL-Bus is Based on 80486 Local Bus Design
The general architecture of the VL-Bus is designed to Intel® 80486 CPU local bus standards with
additional hardware functions that accommodate VL-Bus master devices and facilitate the system I/O bus
interface. The timing specifications allow VL-Bus devices to operate at the full 32-bit 80486 CPU
bandwidth.
seven EISA expansion slots ar e EISA (NOT Vl-Bus) bus mastering slots.
Both VL-Bus slots on the Enterprise-IV motherboard have bus mastering capability.
Six of the
EISA and Local Bus Expansion
The American Megatrends Enterprise-IV EISA Local Bus motherboard has seven expansion slots. Six of
these slots are EISA bus mastering slo t s. One is an EISA non-bus master slot. Two slot s are VL-Bus bus
mastering slots. The VL-Bus slots consist of a standard EISA 32-bit slot connector and an inline VL-Bus
connector.
Enterprise-IV EISA VLB Motherboard User's Guide
Introduction to VL-Bus,
Continued
The following graphic shows the EISA and VL-Bus expansion slots. You can install 16-bit ISA or 32-bit
EISA adapter cards in any expansion slot, including the VL-Bus slots. The VL-Bus expansion slots include
one EISA slot that has both EISA and VL-Bus bus mastering (SLOT 6) slot and one VL-Bus master slot
(SLOT 7) that is an EISA non-bus mastering slot.
EISA or ISA adapter cards have no VL-Bus functionality when installed in a VL-Bus expansion slot.
The current VL-Bus expansion socket specification includes a 16-bit MCA® (Micro Channel Architecture)
expansion socket inline with a standard 32-bit EISA expansion socket connector.
A future VL-bus specification will use a 32-bit MCA connector (a total of 64 bits). The VL-Bus
specification supports 32-bit EISA adapter cards.
The VL-Bus Adapter Cards have a different set of connectors on the bottom of the card and will only fit in
the VL-Bus expansion sl ots.

Step 4 Install Upgrade Processor
Follow the procedures described in this step to install an upgrade processor in the empty ZIF socket near the
CPU.
Improper Upgrade Processor installation can
damage the Upgrade Processor and/or the
motherboard. You must follow the procedures in
this section exactly as documented.
Processor Type and Speed
The Upgrade Processor socket is a 240-pin socket near one edge of the board. The Enterprise-IV VLB
EISA motherboard supports the following CPUs and Upgrade Processors:
Upgrade Processor in ZIF Socket PQFP CPU
None 486DX
P23T, 487SX, or P24T 486DX
P23T, 487SX, or P24T
486DX or 486DX2
486DX or 486DX2 486DX
486SX
486SX 486DX
Warning
The Enterprise-IV VLB EISA motherboard also supports future Intel processors and upgradeable
processors.
Chapter 3 Installation
Step 4 Install Upgrade Processor,
Installing an Upgrade Processor
The following discussion applies only to 169-pin processors, such as the 486DX, 486DX2, 486DX3,
486SX, 80487SX, P23T, or P24. Upgrade Processor installation is easy because a ZIF (zero insertion force)
socket is used.
Step Action
1 Lift the lever on the ZIF socket. The empty Upgrad e Processor sock et
looks like this.
2 Pin 1 of the socket has a white diagonal line across one corner on the
motherboard, which corresponds to pin 1 of the Upgrade Processor.
Check for bent pins on the Upgrade Processor chip. Gently straighten any
bent pins with pliers. Place the Upgrade Processor squarely in the middle
of the socket,

Step Action
Continued
Installing a P24T
The P24T Upgrade Processor is a 240-pin package that uses all socket pins. Use the same procedure
describe above to install the P24T. However, when a P24T Upgrade Processor is properly installed, it uses
all 240 pins, so no extra socket pins can be seen.
Step 5 Install the Motherboard
The mounting holes on the motherboard are the same as an AT motherboard. Standoffs and mounting
screws should be supplied with the chassis.
Step Action
1 Wear an antistatic wristband. Place the chassis for the motherboard on an
anti-static mat.
2 Connect the chassis to ground to avoid static damage. Connect an
alligator clip with a wire lead to any unpainted part of the chassis. Ground
the other end of the lead to the same point as the mat and wristband.
3 Rotate the chassis so that the front is to the right, and the rear is to the left.
The side facing you is where the motherboard is mounted. The power
supply is mounted near the back end of the chassis.
4 Push four nylon standoffs from the solder side of the motherboard in the
holes provided for them. The standoffs lock in place.
5 Find the slots provided for the standoffs on the chassis. Hold the
motherboard, component-side up, with the edge with three standoffs
toward you and the edge with the power supply connector away from you.
The edge connectors for the adapter cards should be on the left.
6 Carefully slide the motherboard into the chassis. Make certain that the
standoffs fit the slots provided for them. If the standoffs are properly
locked, the motherboard should not slide. It should also rest level with the
chassis. The far edge should fit the slots in the plastic clips.
7 Place the two mounting screws in the holes provided for them and tighten
them. If necessary, shift the motherboard slightly to align the mounting
holes on the motherboard with the holes on the chassis.
Be sure to use plastic standoffs.
Chapter 3 Installation
The motherboard mounting hole locations are shown below.

Enterprise-IV EISA VLB Motherboard User's Guide
Step 6 Connect the Power Supply
The power supply should match the physical configuration of the chassis. Make sure that the power switch
is Off before assembly.
Before attaching the power cables, make sure that the proper voltage is selected. Power supplies often can
run on a wide range of voltages, but must be set (usually with a switch) to the proper range. Use at least a
230 watt power supply that has built-in filters to suppress radiated emissions. If all EISA expansion slots are
filled, a standard 200-250 watt power supply is not sufficient, a 300-450 watt power supply is needed. The
location of the power supply connectors (P1, P2, and P3) is shown in the following graphic.
Connect to P1 and P2
The connector with three red wires and two black wires is attached to P2. The connector with the Orange
line 1 is attached to P1. P3 is provided for high capacity power supplies that have an extra cable. The
following graphic shows the wire colors for all power connectors.

Step 9 Connect Cables
When attaching connectors to the motherboard, make sure you attach the correct end. Most connector wires
are color-coded. Match the color of the wires leaving pin 1 on the switch or LED to pin 1 on the connector
end. There may be more than one connector with the same color-coded wires. If so, follow the wire to the
switch or LED. Pin 1 of all connectors is labeled on the motherboard. Sometimes the label is obscured by a
part. You can always identify Pin 1 by looking at the other side of the motherboard. All Pin 1 locations are
always identified by a square pad.

Chapter 5 AMIBIOS Setup
Section 1
Running AMIBIOS Setup
AMIBIOS Setup resides in ROM and is available when the computer is turned on. AMIBIOS Setup permits
the end user to configure these system parameters (type of disk drives and monitor, day, date, and time, and
so on). The parameters are stored in CMOS RAM. When the computer is turned off, a back-up battery
provides power to CMOS RAM, which retains these parameters. The system is configured with these values
when powered on.
Default Values
If the configuration values in CMOS RAM become corrupted, the system is configured with the default
settings stored in this ROM file. There are two sets of BIOS settings stored in the ROM file: the BIOS
Setup defaults and the Power-On defaults. See page 61 for more information on default settings.

shadowing, BIOS code is copied from slower ROM to faster RAM. The BIOS is then executed from the
RAM. This option permits the contents of memory locations F0000h – FFFFFh to be copied from ROM to
RAM for quicker execution and controls whether these contents can be written to or read from cache
memory. The settings are:

Humidity
The recommended humidity range for operation of the American Megatrends Enterprise-IV EISA VLB
motherboard is 20% to 80% non-condensing.
Enterprise-IV EISA VLB Motherboard User's Guide
Power Considerations
Power Supply Requirements
The Enterprise-IV EISA VLB motherboard requires +5V, -5V, +12V, -12V, and about 44 Amps maximum.
Power Consumption
The four SIMM memory banks consume 2 Amps each, for a total of 8 Amps.
Each EISA expansion slot is gated at 4.5 Amps maximum. There are eight EISA expansion slots, so the
total power consumption for EISA expansion slots is 36 Amps. The total maximum power consumption is
44 Amps at +5V with a 220 Watt power supply.
Power Source
Three power connectors (P1, P2, and P3) are provided on the Enterprise-IV EISA VLB motherboard. These
connectors provide seven +5V connects. Each is rated at approximately 5 Amps. The total power
consumption for all three connectors is approximately 35 Amps.
Conclusion
The minimum rating of the power supply should be 230 Watts for a fully loaded motherboard, including a
12V power source. The maximum power consumption on each EISA slot is 4.5 Amps at 5V.
Appendix A Temperature and Power Considerations
Appendix B
Heat Dissipation
The 50 MHz 80486DX and 66 MHz 80486DX2 and P24T are very high performance CPUs that can rival
the performance of any currently available CPU, including RISC processors. However, there is an
undesirable side effect to the high performance — t he heat generated by high power consumption.
These CPUs can dissipate 5 – 8 watts of power. Since this power is concentrated in a small area, it is
necessary to remove the heat generated by this power consumption. For this reason we have supplied a heat
sink with all American Megatrends motherboards that have a 50 MHz 80486DX/DX2 or 66 MHz
80486DX2 CPU.
Since American Megatrends manufactures only the motherboard and CPU Card system components,
American Megatrends has no control over operating factors such as air flow and ambient temperature inside
the computer case. The system integrator must make sure that the CPU always operates within a safe
operating temperature range .
Enterprise-IV EISA VLB Motherboard User's Guide
Heat Dissipation,
Continued
Test Procedure to Assure Proper Operating Temperatures:
1. Install the motherboard in a fully loaded system.
2. Install a temperature sensor (such as a thermocouple) so that the surface of the heat sink can be
measured without opening the case.
3. Turn on the system and run a diagnostics utility program such as AMIDiag for at least one hour.
Expected Results
If the temperature on the surface of the heat sink is 75 degrees centigrade or below, there will be no
problem with the operation of the computer.
Identifying a Problem
If the temperature exceeds 75 degrees centigrade, the system integrator must take the necessary measures to
ensure that the CPU does not overheat.
Potential Solutions
• Install a fan to increase the air flow over the CPU. Some power supplies may have larger or more
powerful fans.
• Install a different heat sink with a greater surface area.
• Different case styles may have better ventilation allowing for more air-flow over the CPU.
