Information for DOS/Windows 3.1x
Users
The following information may be useful if you install EZ-SCSI on a
computer running DOS, Windows 3.1x, or Windows for Workgroups
3.1x.
DOS and Windows 3.1x Device Driver
Devices drivers are software programs that enable your computer to
communicate with SCSI devices such as hard disk drivers, CD-ROM
drivers, and scanners. Each kind of device requires a different device
driver. Adaptec EZ-SCSI includes several DOS/Windows 3.1x device
drivers that are copied to your hard disk during installation. Adaptec
EZ-SCSI adds command lines to your config.sys and autoexec.bat files
to load these device drivers if it finds these kinds of devices on your
computer system.
To learn more about the EZ-SCSI device drivers, including their
command line option information, see the Windows Help application.
