Introduction
In SDMS 4.0, the SCSI BIOS for the Symbios Logic family of PCI SCSI chips is
capable of mapping SCSI hard disk drives behind any non-SCSI hard disk drives
(IDE, ESDI, etc.) within the same system. A driverless solution will allow connec-
tion of up to 24 hard drives (SCSI and non-SCSI) under DOS 5.0 and above.
Full Virtual DMA Services (VDS), including features such as scatter-gather, are
also supported by the SCSI BIOS. Therefore, to gain maximum performance, you
should disable any double buffer option provided by disk caching software (such as
Microsoft’s SMARTDRV.EXE) for all drives handled through SDMS.
When You Need to Load Drivers
Connecting peripherals other than hard disk drives requires loading the appropriate
driver. Some of the drivers work together, and some are capable of direct communi-
cation with a Symbios Logic PCI/SCSI controller.
ASPI8XX.SYS is an ASPI (Advanced SCSI Programming Interface) manager which
provides standard ASPI compatibility between your SCSI host adapter hardware
and ASPI compatible applications. SYMDISK.SYS is a device driver for SCSI disk
drives, and works through the ASPI manager. SYMCD.SYS is a device driver for
CDROM drives, and works through the ASPI manager.
The following sections list these drivers, their features, and their loading require-
ments.
Automatic Installation of SDMS for DOS
Using the DOS Installation Utility
The Symbios Logic SDMS DOS installation utility provides a quick and easy method
for performing either an automatic or custom installation of the SCSI device drivers
in a DOS/Windows environment.
It works with any system using an SDMS supported Symbios Logic SCSI chip. The
installation utility identifies the system, scans the SCSI bus, and properly installs
the needed SCSI device drivers.
The SDMS Drivers diskette containing the DOS device drivers also holds the DOS
installation utility. To use the utility, insert disk 1 into your floppy drive while in the
DOS environment, and change to the A:\DOS directory, then type: INSTALL.
Follow the directions presented on the screens.
When performing a custom installation, an understanding of the information pre-
sented in the following sections for manual installation may prove useful.
