SECTION 1 - INTRODUCTION
The MCSI IRV-3702 Celeron All-In-One Single Board Computer (SBC) contains all the basic elements
found in a high-performance IBM PC/AT compatible desktop computer system plus some unique
features that make it ideally suited for industrial applications. The most outstanding features include:
An optional 32MB PROMDISK-Chip
Disk Emulator, dual PCI EIDE hard disk ports to support four
EIDE drives, a high performance multi-I/O controller, a WatchDog timer, a 1K-bit E
2
Key memory for
user data, and a 10/100Mbps Ethernet Port. The board uses the Intel 82443BX advanced chipset, and
the S3 Trio 3D/2X Graphics controller. The multi-I/O controller includes: dual 16C550 UARTs, a
floppy port, and a SPP/EPP/ECP multi-mode bi-directional parallel port. The optional PROMDISK-
Chip Disk Emulator comes complete with ROM-DOS version 6.22, making it ideal for embedded
diskless applications. The 1K-bit E
2
Key memory is a non-volatile memory useful for storing user data,
such as: critical system parameters, terminal address, etc. The WatchDog timer is ideal for controlling
critical processes where unattended operation is essential.
The IRV-3702 SBC is fully compatible with the ISA Bus and the PCI Bus (version 2.1) which means
virtually all the software written for the IBM PC/AT will run on the IRV-3702 SBC.
