1. Introduction

1. Introduction

This chapter describes how the ASUS PCI-SC896 Host Adapter interfaces to
PCI computer systems and includes these topics:

• Section 1.1, “General Description”

• Section 1.2, “Features”

• Section 1.3, “Interface Descriptions”

1.1 General Description

ASUS PCI-SC896 Dual Channel PCI to Ultra2 SCSI host adapter board pro­vides two SCSI-3, Ultra2 SCSI interfaces to PCI computer systems that re­quire BIOS support on the add-in SCSI adapter . Installing this adapter in your
PCI system allows connection of SCSI devices over a SCSI bus. The dual
channel PCI-SC896 board provides 16-bit Low Voltage Differential (LVD)
and Single-Ended (SE) SCSI solutions for your computer, using only one PCI
slot. This board supports legacy Fast SCSI devices, Ultra SCSI devices, and
the newest Ultra2 SCSI devices. ASUS SCSI Device Management System
(SDMS™) software operates the board, but the design of the board does not
prevent other software to be used with it. BIOS support for this host adapter is
incorporated on the board in a 128K Flash device. This guide and the PCI
SCSI Device Management System SDMS 4.0 User’s Guide contain product
information and installation instructions to help you gain the full benefits of
your PCI-SC896 Dual Channel PCI to Ultra2 SCSI host adapter for your com­puter system.

1. Introduction

1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI Interface, the
SCSI Interface, the SCSI Activity LED Interface, and Wide Ultra2 SCSI.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O compo­nents to a PC processor and memory subsystem. The PCI functionality for the
PCI-SC896 is contained within the ASUS PCI-SC896 PCI-SCSI I/O Processor
chip. The PCI-SC896 connects directly to the PCI bus and generates timing
protocol in compliance with the PCI specification. The PCI interface operates as
a 32-bit DMA bus master. The connection is made through the edge connector
J1. The signal definitions and pin numbers conform to the PCI Local Bus Speci­fication Revision 2.1 standard. The PCI-SC896 conforms to the PCI universal
signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface

The SCSI functionality for the PCI-SC896 is contained within the ASUS PCI­SC896 PCI-SCSI I/O Processor chip. The PCI-SC896 connects directly to the
two SCSI buses for SE or LVD SCSI applications and generates timing and
protocol in compliance with the SCSI standard. Each SCSI interface operates
at a burst transfer rate of up to 40 Mbyte per second for wide single-ended
transfers, and up to 80 Mbyte per second for wide LVD SCSI transfers.

1. Introduction

The SCSI interfaces on the PCI-SC896 operates as two 16-bit, synchronous or
asynchronous, single-ended or LVD, and supports Ultra2 SCSI protocols and
16-bit arbitration. The PCI-SC896 board provides autosensing, dual mode SE/
L VD SCSI termination. T ermination is normally enabled. When a SCSI device
is sensed to be connected to both internal and external connectors, termination
for that channel is automatically disabled. The PCI-SC896 supplies SCSI bus
TERMPWR (termination power) through a blocking diode and self-resetting

1.5 A short circuit protection device. An on-board LED lights up when
TERMPWR is shorted and turns off. A 40 MHz oscillator is installed on the
PCI-SC896 board to provide the clock frequency to the PCI-SC896 that is
necessary to support Wide Ultra2 SCSI transfers of up to 80 Mbytes/s.
