Installation Guide for the Symbios SDMS Drivers: SYMC8XX.SYS V4.13.00 SYM_HI.SYS V4.13.00 LSI_U3.SYS V5.01.00
This file describes the features and use of the Symbios SDMS device drivers for the Windows NT 3.5x/4.x operating system environment. It is divided into the following sections:

Windows NT is an operating system designed to run on processors using current technology. It provides a graphical user interface environment incorporating many high-level features (refer to the Microsoft Windows NT documentation for details). An I/O manager handles I/O requests in Windows NT. To address a SCSI peripheral, the I/O manager goes through the appropriate drivers. Class drivers for hard disk, floptical, CD-ROM, printer, and scanner peripherals are provided in Windows NT.
Other class drivers, provided by peripheral manufacturers, may be added to support new devices. Tape device support is built into the operating system itself and does not require a class driver. LSI Logic and Microsoft provide miniport drivers, called SYMC8XX.SYS, SYM_HI.SYS, and LSI_U3.SYS to complete the path to a Symbios controller or processor with an optional SDMS SCSI BIOS. The next sections describe these drivers and their installation. * * * * * * * * * * * Features * * * * * * * * * * * *

The SYMC8XX.SYS driver is named "Symbios PCI (53C8XX)" for driver installation. It supports the following devices and Symbios host adapters based on those devices:
o SYM53C810, SYM53C810A, SYM53C810AE (SYM8100S, SYM8100ASP) o SYM53C815 (SYM815XS, SYM8150SP)
