Introduction
The LSI22915A has two 16-bit Low Voltage Differential (LVD) and
Single-Ended (SE) Ultra160 SCSI channels that connect to the PCI local
bus on your computer. The LSI22915A is tailored to systems that require
on-board BIOS support. When you install the LSI22915A in your PCI
system, you can connect up to 15 SCSI disk drives and other SCSI devices
to each of its two SCSI channels. In addition to Ultra160 SCSI devices, the
LSI22915A also supports legacy Fast, Ultra, and Ultra2 SCSI devices.
The LSI22915A controls the SCSI devices that are connected to it. The
chain of internal and external SCSI devices connected to each SCSI
channel is referred to as a SCSI bus.
Storage Device Management System (SDMS™) software operates the
board. However, the design of the board allows you to use other SCSI
software. BIOS support for this host adapter is incorporated on the board
in a 128 Kbyte Flash EEPROM.
