Page 7: Section 1 - Introduction
Pentium SBC was specifically designed to operate in extreme industrial environments, and has an operating temperature range of 0 o to 60 o C. 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.

Page 9: Section 2 - System Description
YSTEM EMORY 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...
Page 10: Dma Controller
DMA C ONTROLLER 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).
Page 11: Timers
OUSE The IRV-686H SBC contains an IBM PS2 compatible mouse port for interfacing to a generic serial mouse. The mouse port controller assembles the serial data from the mouse into bytes and interrupts the CPU via IRQ1 after each byte is ready to be read. The IRQ1 service routine reads port 60H to get the scan code and acknowledges by sending a positive pulse to port 61H to clear the interrupt for the next byte.
Page 12: Printer Port
VGA D ISPLAY The IRV-686H SBC includes a PCI VGA display controller and graphic accelerator as part of the SIS- 5598 ChipSet which interfaces directly to the local on-board PCI bus. The VGA display port is fully compatible with IBM VGA, EGA, CGA, and MDA display adapters, and provides improved performance and additional functionality.

NTERFACE The IRV-686H SBC includes a PC/104 compatible interface port. The PC/104 interface port allows the IRV-686H board to operate in a standalone configuration which makes it ideal for embedded applications. The PC/104 standard offers total hardware and software compatibility with the PC/ISA bus architecture using ultra small stackable modules.
Page 14: Section 3 - Setup
3 - S ECTION ETUP The IRV-686H SBC uses the latest AWARD Plug-n-Play BIOS which contains an internal Setup Utility for configuring the system. The BIOS includes a graphical user interface, and a new system configuration utility, as well as all the features of the standard BIOS. The system configuration settings are stored in the on-board CMOS memory which is backed up by a Lithium battery.
