FCC Standards
The FCC (Federal Communications Commission) restricts
the amount of radiation and radio frequency emissions
coming from computing equipment.
Note: This equipment has been tested and found to comply
with the limits for a Class B digital device pursuant to Part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference
to radioor television reception, which can be determined by
turning the equipment off and on, the use is encouraged to try
to correct the interference by one or more of the following
measures:
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and
receiver.
•
•
Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician
for help.

Processor Speed Ratio JP32, JP31, JP30, JP29
The PentiumPro uses a clock multiplier to run at a
speed faster than the processor bus.
These jumpers match the installed processor’s speed with
single board computer’s defined processor speed.
When upgrading processors, you may need to adjust these
jumpers.

System Memory
There are a total of four banks available for memory
upgrades. The board supports DIMM in the following
combinations:
1M x 64/72
2M x 64/72
4M x 64/72
8M x 64/72
= 8 MB/bank
= 16 MB/bank
= 32 MB/bank
= 64 MB/bank
16M x 64/72 = 128 MB/bank
32M x 64/72 = 256 MB/bank
Installing and Removing DIMM
Read these instructions completely before installing or
removing DIMMs. The DIMM is held by plastic press-clips
on both sides of the slot.
Installing DIMM
1) Hold the DIMM so that the gold tab is pointing toward the
slot. The DIMM is keyed so that it will only snap into the
slot when positioned correctly.
2) Press one end of the DIMM until it inserts and its press-
clip snaps into place.
3) Press the other end of the DIMM until it inserts and its
press-clip snaps into place.
Removing DIMM
1) Pull both press-clips simultaneously, until the DIMM pops
up from its slot.

Note: IRQ9, IRQ10, IRQ11, IRQ12, IRQ15, IRQ3, IRQ4,
IRQ5 and IRQ7 can be redirected to PCI add-in boards.
The PCI standard has a 4-IRQ limitation. Some PCI add-in
boards do not require IRQs. Some can share an IRQ with
another board of the same model and manufacture. Check the
add-in board’s docmentation for IRQ information.
Direct Memory Access
The system supports seven DMA channels:
Controller 1
Controller 2
Channel 0 - Spare
Channel 4 - Cascade
for Controller 1
Channel 1 - SDLC
Channel 2 - Diskette
Channel 3 - Spare
Channel 5 - Spare
Channel 6 - Spare
Channel 7 - Spare
The first DMA controller holds channels 0 through 3. These
channels support 8-bit data transfers between 8-bit I/O
adapters and 8- or 16-bit system memory. Each channel can
transfer data in 4 KB blocks.
The second DMA controller holds channels 4 through 7.
Channel 4 cascades channels 0 through 3 to the
microprocessor. Channel 5, 6 and 7 support 16-bit data
transfers between 16-bit I/O adapters and 16-bit system
memory. These DMA channels can transfer data throughout
the 16 MB system-address space in 128 KB blocks.
Channel 5, 6 and 7 cannot transfer data on odd byte
boundaries.

Configuration Utilities
Overview
The BIOS Setup utility stores your system’s configuration.
The utility described below provides a bridge to PCI slots in
excess of the four allowed by current standards.
When your system “boots”, it’s configuration is read into
main memory. Hard drives, floppy drives, video adapter,
memory and keyboard are described to the system.
The BIOS is pre-configured at the factory. This document is
an overview of the BIOS.
To start the program, press the <Delete> key while the
system is booting. The Utilities menu screen will display:
