INTRODUCTION
Introduction
Product Description
I815E is a high-performance flexible embedded board based on the Intel 815E chipset that contains the Graphics and Memory Controller Hub (GMCH), the I/O Controller Hub (ICH2) and the Firmware Hub (FWH). It supports 66/100/133MHz system bus, up to 1.4GHz CPU speed, integrated 2D/3D graphics accelerator, and PC100/PC133 SDRAM modules. With the ICH2, it is able to support UDMA33/66/100, four USB ports, and integrated LAN.
System memory is provided by one 168-pin DIMM socket that accommodates SDRAM with a maximum capacity of 256MB. The Award BIOS facilitates easy system configuration and peripheral setup. Other advanced features include four USB ports, 256-level watchdog timer (supported by LPC I/O IT8712), and IrDA interface.

Installing the CPU
The I815E board 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:
cause your system to hang or be unstable.

Installing the Memory (DIMM)
The I815E board supports one 168-pin DIMM socket for a maximum total memory of 256MB in SDRAM type. The memory module capacities supported are 32MB, 64MB, 128MB and 256MB.
Installing and Removing DIMMs
To install the DIMM, locate the memory slot on the board 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.

Configuring the CPU Frequency
The I815E board does not provide DIP switches to configure the processor speed (CPU frequency). However, the processor speed can be configured inside the BIOS Setup. Refer to the BIOS Setup section in this manual on how to change the processor speed.
JP2: Clear CMOS Contents
Use JP2, a 3-pin header, to clear the CMOS contents. Note that the ATX-power connector should be disconnected from the board before clearing CMOS.

Use JP9 and JP10 2-pin jumpers when overclocking the CPU bus speed from 66MHz to 100MHz or 100MHz to 133MHz. Refer to the table below. Note that some processors cannot be overclocked because their bus speed has been ‘locked’ by the manufacturer and overclocking can cause the system to hang or become unstable.
