Chapter 1. Introduction
Thank you for choosing ROCKY-3702EV Socket 370 Celeron®
and Pentium III ( FC-PGA ) with AGP VGA & 10/100Mbps
Ethernet Single Board Computer. The ROCKY-3702EV is a
PICMG bus form factor board. It is equipped with high
performance Intel®Celeron up to 950MHz and Pentium III ( FC-
PGA ) 1GHz ( or above ) Processor and advanced high
performance multi-mode I/O, designed for the system
manufacturers, integrators, or VARs that want to provide all the
performance, reliability, and quality at a reasonable price.
This board has a built-in DiskOnChip™(DOC) Flash Disk for
embedded application. The DOC Flash Disk is 100% compatible
to hard disk which enable users to use DOS command without
having to install any extra software utility.
An advanced high performance super AT I/O chip – Winbond
W83977EF is used in the ROCKY-3702EV board. The on-chip
UARTs are compatible with the NS16C550. The parallel port and
IDE interface are compatible with IBM PC/AT architecture.
ROCKY-3702EV uses the advanced INTEL 440BX Chipset which
is 100% ISA/PCI compatible chipset with PCI 2.1 standard. In
addition to all of the above, this board provides four 168-pin
sockets for its on-board DRAM. The DIMM module is 3.3 V
SDRAM and support up to a maximum of 256MB for each
module.

2.2 Unpacking Precautions
Some components on ROCKY-3702EV SBC are very sensitive to
static electric charges and can be damaged by a sudden rush of
power. To protect it from unintended damage, be sure to follow
these following precautions:
 Ground yourself to remove any static charge before
touching your ROCKY-3702EV SBC. You can do it by using
a grounded wrist strap at all times or by frequently
touching any conducting materials that is connected to the
ground.
 Handle your ROCKY-3702EV SBC by its edges. Do not
touch IC chips, leads or circuitry if not necessary.
 Do not plug any connector or jumper while the power is on.
 Do not put your ROCKY-3702EV SBC unprotected on a flat
surface because it has components on both sides.
