ASUS LSI SCSI User’s Manual 3

1. Introduction

General Description

The onboard LSI integrated Dual Channel Ultra2 SCSI provides two SCSI-3,

Ultra2 SCSI interfaces that require BIOS support. The dual channel LSI inte-

grated SCSI provides 16-bit Low Voltage Differential (LVD) and Single-Ended

(SE) SCSI solutions for your computer. This supports legacy Fast SCSI de-

vices, Ultra SCSI devices, Ultra2 SCSI devices, and the newest Ultra160 SCSI

devices. PCI SCSI Device Management System (SDMS™) software operates

the chipset, but the design of the chipset does not prevent other software to be

used with it. BIOS support for this chipset is incorporated in the ASUS moth-

erboard BIOS.

SCSI Interface

• Two separate SCSI channels

• 16-bit SE/LVD

• Automatically enabled termination

• One 68-pin high-density for channel A

• One 68-pin high-density for channel B

• Fast, Ultra, and Ultra2 data transfer capability

• SCSI TERMPWR source with autoresetting circuit breaker and

TERMPWR shorted LED for each channel

• SCSI Plug and Play

• SCAM (SCSI Configured AutoMatically).

• Flash EEPROM for BIOS storage

• Serial NVRAM (Non Volatile Random Access Memory) on each chan-

nel for user configuration utility and SCAM information storage
