Important: LSI Logic highly recommends that you backup your system
disk before installing any software. Failure to back up all
files on your system may result in unrecoverable loss of
data.
1.4 Installing the Ultra2 SCSI Drivers
The LSI Logic ITSPS and ITHPS Ultra2 SCSI device drivers are
optimized for low CPU overhead and high I/O throughput, making use of
the LSI Logic single interrupt scripts. The ITHPS driver supports the
ITI8200 adapters that have the LSI53C896 controller. The ITSPS driver
is for another LSI Logic Ultra2 SCSI controller and its associated host
adapters.
The ITSPS and ITHPS device drivers are bundled together and included
in your host adapter kit. This document refers to the installation of the
ITHPS driver. When you install the ITHPS driver, the ITSPS driver is
automatically installed as well. The ITSPS driver supports older LSI Logic
Ultra2 SCSI controllers.
