Specifications

You need to install the ASPI MS-DOS Manager when you want to
do the following:
Install the SCSI adapter card in a system with more than two
hard disk drives
Install a SCSI hard disk drive that has a SCSI ID other than
0 or 1
Install a SCSI hard disk drive with a capacity greater than
1024MB
Install a removable SCSI device, such as a CD-ROM, tape
backup drive, or magneto-optical device
Interface with ASPI modules, such as SY-TOS® devices,
CD-ROM drives, printers, plotters, and scanners
Use MS-DOS programs that run in protected mode, such
as Microsoft
®
Windows™ 3.0, Windows/386, Quarterdeck
QEMM 386, Qualitas 386MAX
Use programs that write large amounts of data directly to
video memory
Change the configuration of the SCSI adapter card
Increase the performance of your SCSI interface.
When you install the ASPI MS-DOS Manager, the computer routes
Interrupt (Int) 13 calls through the driver rather than through the
BIOS of the SCSI adapter card. This means Int 13 calls are
processed at RAM speed instead of ROM speed, which increases
overall system performance.
Installing the ASPI MS- DOS Manager
The filename of the device driver that installs the ASPI MS-DOS
Manager in Standard mode is ASPI4DOS.SYS. The filename of the
device driver that installs the ASPI MS-DOS Manager in Enhanced
mode is ASPIEDOS.SYS. Both of these files are located on the ASPI
MS-DOS Manager diskette.
