Introduction
Product Description
IB780 is a high-performance flexible CPU card based on the VIA Apollo
PLE 133T chipset. The VIA Apollo PLE 133T chipset is based on an
innovative and scaleable architecture with proven reliability. It is a two-
chip set consisting of the VT8601T North Bridge Controller and
VT82C686B South Bridge Controller.
IB780 supports 66/100/133MHz system bus, up 1.2GHz CPU speed, the
VT8601T integrated graphics accelerator. Additional key features
include support for four USB ports, AC-97 link for audio, hardware
monitoring, and power management.
System memory is provided by three 168-pin DIMM sockets that
accommodate SDRAM with a maximum capacity of 1.5GB. The Award
BIOS facilitates easy system configuration and peripheral setup.
Expansion functionality is provided with MicroPCI socket that supports
MicroPCI daughter cards for Ethernet (LAN), SCSI, and IEEE 1394
functions.
Other advanced features include DiskOnChip flash disk support, 16-
level watchdog timer, and IrDA interface.
DiskOnChip flash disks are storage devices that has no moving parts and
emulates FDD/HDD with Flash/RAM/ROM offering reliable
data/program storage and long life span. They are reliable and suitable
for industrial or other harsh environments characterized by motion,
shock, vibration, adverse temperature, dust and humidity. Other features
include faster data access, longer MTBF, lower power consumption, cost
effective for small capacity and small form factor.

Installing the CPU
The IB780 CPU Card supports a Socket 370 processor socket for Intel
Pentium III and Celeron processors.
The Socket 370 processor socket comes with a lever to secure the
processor. Raise this lever to about a 90°angle to allow the insertion of
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, return the
lever to the lock position. Refer to the figures below.
After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.
NOTE:Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

IB780 User’s Manual 7
MicroPCI Daughter Card Installation
The IB780 CPU card is integrated with a MicroPCI socketthat use
SO-DIMM 144-pin connectors. These sockets can accommodate the
optional MicroPCI daughter cards.
To insert the MicroPCI daughter cards, position it at 30°to the PCB and
gently push it into the MicroPCI connector (See Figure 1 below). The
card will not fit when inserted at an angle of 45°or 15°. Once inserted,
slowly press the card towards the PCB until it locks on both sides to the
clips of the connector. Screw the card to the PCB to secure the
installation. To remove the MicroPCI card, pull the‘clips’sideways as
shown in Figure 2 below.

Installing the Memory (DIMM)
The IB780 CPU Card supports three 168-pin DIMM socket for a
maximum total memory of 1.56GB in SDRAM type. The memory
module capacities supported are 64MB, 128MB, 256MB, and 512MB.
Installing and Removing DIMMs
To install the DIMM, locate the memory slot on the CPU card and
perform the following steps:
1. Hold the DIMM so that the two keys of the DIMM align with those on
the memory slot.
2. Gently push the DIMM in an upright position until the clips of the slot
close to hold the DIMM in place when the DIMM touches the bottom
of the slot.
3. To remove the DIMM, press the clips with both hands.
