6.4.4 DOS device drivers
Device drivers are software programs that enable your computer to
communicate with SCSI devices such as hard disk drives, CD-ROM
drives, and scanners. Each kind of device requires a different device
driver. Adaptec EZ-SCSI includes several DOS device drivers that are
copied to your hard disk during installation. If Adaptec EZ-SCSI finds
these kinds of devices on your computer, it adds command lines to
your config.sys and autoexec.bat files to load the necessary device
drivers.
To learn more about the Adaptec EZ-SCSI device drivers, including
their command line option information, refer to the Adaptec EZ-SCSI
Online Reference (a Windows Help application).
6.4.5 DOS ASPI managers
ASPI (Advanced SCSI Programming Interface) managers are software
programs that enable the SCSI device drivers, your host adapter, and
your SCSI devices to communicate with one another. ASPI managers
are written for a specific operating system, such as DOS, and a
specific family of Adaptec host adapters.
Adaptec EZ-SCSI includes several ASPI managers for DOS. When
you install Adaptec EZ-SCSI on these operating systems, it detects
what kind of host adapter is installed in your computer and automati-
cally configures your system with the correct ASPI manager. To learn
more about these ASPI managers, including their command line
option information, refer to the Adaptec EZ-SCSI Online Reference (a
Windows Help application).
