SECTION 1 - INTRODUCTION
The MCSI IRV-686H Pentium/MMX 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 which make it ideally suited for industrial applications. The most outstanding
features include: An optional 32MB PROMDISK-ChipDisk Emulator, a PCI EIDE hard disk port to
support 2 EIDE drives, a high performance PCI VGA Video controller and graphics accelerator, a
high performance multi-I/O controller, a WatchDog timer, a 1K-bit E2Key memory for user data, and
a PC/104 expansion port. The board uses the SIS-5598 Chipset with integral VGA controller and
graphics accelerator. 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 E2Key memory is a non-volatile memory that is useful for storing user data,
such as: critical system parameters, terminal address, etc. The PC/104 expansion bus allows easy
installation of thousands of different PC/104 modules available world wide. The WatchDog timer is
ideal for controlling critical processes where unattended operation is essential. The IRV-686H
Pentium SBC was specifically designed to operate in extreme industrial environments, and has an
operating temperature range of 0oto 60oC.
The IRV-686H SBC is fully compatible with the IBM PC/AT ISA Bus which means virtually all the
software written for the IBM PC/AT will run on the IRV-686H SBC.

SECTION 2 - SYSTEM DESCRIPTION
The following sections describe the major system features of the IRV-686H All-In-One Single Board
Computer.
PROCESSOR
The IRV-686H Pentium SBC supports 100MHz to 233MHz Pentium/MMX, and the AMD K6-2
processor up to 333MHz. It also supports the Cyrix 6x86MX-PR266. The Pentium microprocessor
includes an on-chip 16K-byte unified instruction cache, an 16K-byte data cache, an internal high
performance math co-processor, and an enhanced 64-bit data bus. The on-board jumper selectable
clock generator and ZIF CPU socket makes upgrading to a higher performance CPU easy. Some of
the distinctive features of the processors include:
•64-bit External Data Bus
•32-bit Internal Architecture
•128M-byte Directly Addressable Memory Space
•Internal 14 Word by 32-bit Register Set
•Separate 8K-byte Data and Cache Memories (16K for MMX)
•On-chip Pipelined Floating Point Processor
•Integrated Memory Manager
SYSTEM MEMORY (DRAM)
The IRV-686H Pentium SBC features a shared memory which supports up to 128M-bytes of dynamic
random access memory (DRAM) organized as two banks of 32Mx36 including four parity bits. The
board will support either standard fast page mode or high performance EDO DRAM. The memory
is configured using two single in-line memory module sockets, which will accept 72-pin single in-line
memory modules (SIMMs) organized as 1MB, 2MB, 4MB, 8MB, 16MB, 32MB, or 64MB with a
maximum access time of 70ns. One megabyte of memory is shared by the video controller. The
following table demonstrates some of the most common memory configurations.

4M 1Mx36 Not Installed
8M 1Mx36 1Mx36
8M 2Mx36 Not Installed
16M 2Mx36 2Mx36
16M 4Mx36 Not Installed
32M 4Mx36 4Mx36
32M 8Mx36 Not Installed
64M 8Mx36 8Mx36
64M 16Mx36 Not Installed
128M 16Mx36 16Mx36
CACHE MEMORY
The IRV-686H SBC includes 512K-bytes of pipelined burst mode cache memory for high speed access
to blocks of data most recently read from main memory, including buffered data from the disk and
video memory. The cache memory will significantly increase system performance over that of a
conventional non-cached system.

DMA CONTROLLER
The IRV-686H SBC memory refresh and DMA functions are included in the System Controller chip
which includes the equivalence of two 82C37 DMA controllers. The two DMA controllers are
cascaded to provide four DMA channels for transfers to 8-bit peripherals (DMA1) and three channels
for transfers to 16-bit peripherals (DMA2). DMA2 Channel 0 provides the cascade interconnection
for the two DMA devices thereby maintaining IBM PC/AT compatibility. The DMA channel
assignments are listed below:
DMA Channel 0: Not Used (8-bit)
DMA Channel 1: Alternate for Multi-mode Parallel Port (8-bit)
DMA Channel 2: Floppy Disk (8-bit)
DMA Channel 3: Multi-mode Parallel Port (8-bit)
DMA Channel 5: Not Used (16-bit)
DMA Channel 6: Not Used (16-bit)
DMA Channel 7: Not Used (16-bit)
The DMA request (DRQx) and acknowledge (DACKx/) lines are available on the P1 98-pin edge
connector.
INTERRUPT CONTROLLER
The IRV-686H SBC has the equivalence of two 82C59A interrupt controllers included in the System
Controller chip. The controllers accept requests from peripherals, resolve priorities on pending
interrupts and interrupts in service, interrupt the CPU, and provide the vector address of the
interrupt service routine. The two interrupt controllers are cascaded in a fashion compatible with the
IBM PC/AT. The interrupt priority and assignments are shown below in descending order of
priority:
Highest IOCHCK/ Parity Check (Non-maskable)
IRQ0 System Timer (Not Available)
IRQ1 Keyboard (Not Available)
IRQ8 Real Time Clock (Not Available)
IRQ9 SVGA Controller
IRQ10 Not Used
IRQ11 Alternate for Serial Port 2
IRQ12 Alternate for Serial Port 1
IRQ13 Co-processor (Not Available)
IRQ14 Not Used
IRQ15 Not Used
IRQ3 Serial Port 2
IRQ4 Serial Port 1
IRQ5 Alternate for Parallel Port
IRQ6 Floppy Disk Controller
Lowest IRQ7 Parallel Port
The interrupt request lines IRQx and IOCHCK/ are available on the 98-pin edge connector except as
noted above.
