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.

standard
 Dual Auto-sensing interface to 10Mbps,
100Mbps Network
 RJ45 connector for 10BASE-TX and 100BASE-TX
 Full Duplex capability
 Full Software driver support
•Ultra DMA/33 (Enhanced PCI IDE Interface) : up to four
PCI Enhance IDE hard drives. The Ultra DMA/33 IDE can
handle data transfer up to 33MB/s. Best of all is that this new
technology is compatible with existing ATA-2 IDE
specifications so there is no need to change any of customer’s
current accessories.

•Multi-I/O Chip :
 W83977, all I/O setup by BIOS
 Two 16C550 RS-232C Ports
 One EPP/ECP Parallel Port, Floppy Port
•Floppy disk drive interface : Two 2.88 MB, 1.44MB, 1.2MB,
720KB, or 360KB floppy disk drives.
•Two high speed Serial ports : NS16C550 compatible
UARTs
•Bi-directional Parallel Port

program. It is useful for storing system ID, Password and
other crucial data on the board.
•Watch-dog timer : Can be set by 1, 2, 10, 20, 110 or 220
seconds per period. Reset or NMI is generated when CPU
does not periodically trigger the timer. Your program uses
hex 043 and 443 to control the watch-dog and generates a
system reset.
