1.1General Description

The LSI Logic LSI20160 provides one SCSI-3, Ultra160 SCSI interface 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 LSI20160 provides one Ultra160 SCSI channel. The LSI20160 supports Low Voltage Differential (LVD) and Single-Ended (SE) SCSI. This board supports Fast/Ultra/Ultra2 SCSI devices as well as the newest Ultra160 SCSI devices.

The LSI Logic Storage Device Management System (SDMS™) software operates the board. The design of the board does not prevent other SCSI software from being used with it. BIOS support for this host adapter is incorporated on the board in a 128 Kbyte Flash device. The onboard controller for the LSI20160 is the LSI53C1000 PCI to Ultra160 SCSI Controller.
