Introduction
Product Description
The IB820 Pentium 4 Full Size PICMG CPU Card incorporates the
Intel® advanced 845G Chipset Memory Controller hub and supports
478-pin Intel Pentium 4 processors of 1.3GHz and up to 3.06GHz+ with
FSB 533MHz/400MHz. IB820 supports the Pentium 4 processor with
256-KB L2 cache and the Pentium 4 processor with 512-KB L2 cache on
0.13 micron process.
The I/O functions are on IB820 integrated onto the ICH4. It supports
either the integrated graphics device (IGD) on the GMCH or an external
graphics device on AGP. The IGD has 3D, 2D, and video capabilities. The
system memory size can be up to 2 GB, using the two DDR sockets on
board. Six USB ports are supported with the USB 1.1/2.0 standard.
IB820 optionally supports the ATI Mobility M7 graphics controller with
16MB or 32MB embedded memory. Interface supported are LVDS,
TMDS and dual CRT. The VGA functionality offers unprecedented video
quality and integrated MPEG-2 decode capability. IB820 also
optionally comes with an Intel 82540 Gigabit LAN controller for faster
networking access.
IB820 supports a MicroPCI socket for MicroPCI daughter cards with
VGA, VGA/LAN, Ethernet (LAN), SCSI, and IEEE 1394 functions.
This CPU card represents the perfect choice for those who want superior
performance for rugged and demanding applications in industrial
automation, image processing, multimedia and telecommunications.

Installing the CPU
The IB820 CPU Card supports a Socket 478 processor socket for Intel
Pentium 4 processors.
The Socket 478 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.

INSTALLATIONS
IB820 User’s Manual 7
ATX Power Installation
The system power is provided to the IB820 CPU card with the J1 and J8
ATX power connectors. Please note that the J8 external ATX power
connector should be connected to the backplane for IB820 to function. J8
is a 3-pin power connector. J1 is a 4-pin 12V power connector. J1 is to be
connected to the ATX power supply.
MicroPCI Daughter Card Installation
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.
Figure 1. Figure 2.

Installing the Memory
The IB820 CPU Card supports two DDR memory sockets for a
maximum total memory of 2GB in DDR memory type. The memory
module capacities supported are 64MB, 128MB, 256MB, 512MB and
1GB. The following table lists the supported SDR DIMM configurations.
Intel 845G supports configurations defined in the JEDEC DDR DIMM
specification only (A,B,C). Non-JEDEC standard DIMMs such as
double-sided x16 DDR SDRAM DIMMs are not supported.

Installing and Removing Memory Modules
To install the DDR modules, locate the memory slot on the CPU card and
perform the following steps:
1.Hold the DDR module so that the key of the DDR module align with
those on the memory slot.
2.Gently push the DDR module in an upright position until the clips of
the slot close to hold the DDR module in place when the DDR module
touches the bottom of the slot.
3.To remove the DDR module, press the clips with both hands.
