ASW-410 Installation Utility
=====================================
OVERVIEW:
=========
This disk contains the Adaptec ASW-410 Installation Utility
(INSTALL.EXE) for the ASW-410 CD-ROM drivers (ASWCDxxx.SYS).
It can be invoked by simply making the drive which has the
INSTALL.EXE, ASWCDxxx.SYS, and MSCDEX.EXE files the current
drive and typing "install".
The Adaptec ASPI CD-ROM module for DOS will work with all
Adaptec SCSI host adapters, provided that a DOS ASPI Manager
is loaded (via the CONFIG.SYS).
To use this utility, the end user must receive the following
files:
(1) INSTALL.EXE - Install utility executable code
(2) INSTALL.HLP - Install utility help file for C-Worthy 2.0
(3) INSTALL.CWA - Install utility C-Worthy menus and screens
(4) MSCDEX.EXE - Microsoft MS-DOS CD-ROM Extensions
(5) ASWCDxxx.SYS - Appropriate CD-ROM driver
Alternate Installation Procedure:
=================================
Installation requires modifying the CONFIG.SYS and AUTOEXEC.BAT
files. You must also copy the driver onto your hard disk, along
with the file MSCDEX.EXE.
CONFIG.SYS
- The DOS ASPI Manager for the host adapter should be loaded
before any other ASPI modules, including the CD-ROM module.
- Use the DEVICE command for each driver you are using. The format is:
DEVICE = [path] ASWCDxxx.SYS /D:device_name
Note that this driver resets the SCSI when the driver initializes
itself. This reset may cause problems if the SCSI bus has other
devices connected, such as a bootable hard drive. The reset may be
disabled with a command line option as follows:
DEVICE = [path] ASWCDxxx.SYS /D:device_name /NORST
The "/NORST" causes the driver to not reset the SCSI bus. If it
is not included, the default is to reset the bus.
- Use the LASTDRIVE command to reserve enough drive letters.
- FILES and BUFFERS should be set to at least 20.
- A sample CONFIG.SYS might look like:
DEVICE=ASPI4DOS.SYS (for AHA-1540, 1640, and 1740 (standard mode))
DEVICE=C:\ASWCDSNY.SYS /D:ASPICD0
LASTDRIVE=N
FILES=20
BUFFERS=20
AUTOEXEC.BAT
-AUTOEXEC.BAT is used to load the Microsoft Extensions, MSCDEX.EXE.
This allows a CD-ROM to be recognized as a single logical drive
letter under DOS. It is not required to include MSCDEX.EXE in
AUTOEXEC.BAT, but is a convenience so that the CD-ROM is ready to
use when the system is booted up.
-The format of MSCDEX.EXE is:
MSCDEX.EXE /D:<device_name> /L:<drive_letter> /M:xx /V /E
where:
/D device_name is the same as in CONFIG.SYS. In the above
example is was ASPICD0.
/L The logical drive letter that will be assigned to the
CD-ROM drive.
/M The number of cache buffers for MSCDEX.EXE (8-15). Each
uses 2048 bytes of RAM. 10 is default.
/V Enables verbose mode, displaying information about
MSCDEX.EXE during boot.
/E Allows MSCDEX.EXE to use expanded memory, if available.

ASW-410 CD-ROM DRIVER FOR DOS: V2.1
========================================
OVERVIEW:
=========
This disk contains the Adaptec ASPI CD-ROM modules for DOS.
This driver will work with all Adaptec SCSI host adapters, providing
that a DOS ASPI Manger is loaded (via the CONFIG.SYS).
Installation Procedure:
========================
An INSTALL Utility is included in this release. See the Installation
manual supplied for details.
Installation requires modifying the CONFIG.SYS and AUTOEXEC.BAT
files. You must also copy the driver onto your hard disk, along
with the file MSCDEX.EXE.
CONFIG.SYS
- The DOS ASPI Manager for the host adapter should be loaded
before any other ASPI modules, including the CD-ROM module.
- Use the DEVICE command for each driver you are using. The format is:
DEVICE = [path] ASWCDxxx.SYS /D:device_name
Note that this driver resets the SCSI when the driver initializes
itself. This reset may cause problems if the SCSI bus has other
devices connected, such as a bootable hard drive. The reset may be
disabled with a command line option as follows:
DEVICE = [path] ASWCDxxx.SYS /D:device_name /NORST
The "/NORST" causes the driver to not reset the SCSI bus. If it
is not included, the default is to reset the bus.
- Use the LASTDRIVE command to reserve enough drive letters.
- FILES and BUFFERS should be set to at least 20.
- A sample CONFIG.SYS might look like:
DEVICE=ASPI4DOS.SYS (for AHA-1540, 1640, and 1740 (standard mode))
DEVICE=C:\ASWCDSNY.SYS /D:ASPICD0
LASTDRIVE=N
FILES=20
BUFFERS=20
AUTOEXEC.BAT
-AUTOEXEC.BAT is used to load the Microsoft Extensions, MSCDEX.EXE.
This allows a CD-ROM to be recognized as a single logical drive
letter under DOS. It is not required to include MSCDEX.EXE in
AUTOEXEC.BAT, but is a convenience so that the CD-ROM is ready to
use when the system is booted up.
-The format of MSCDEX.EXE is:
MSCDEX.EXE /D:<device_name> /L:<drive_letter> /M:xx /V /E
where:
/D device_name is the same as in CONFIG.SYS. In the above
example is was ASPICD0.
/L The logical drive letter that will be assigned to the
CD-ROM drive.
/M The number of cache buffers for MSCDEX.EXE (8-15). Each
uses 2048 bytes of RAM. 10 is default.
/V Enables verbose mode, displaying information about
MSCDEX.EXE during boot.
/E Allows MSCDEX.EXE to use expanded memory, if available.
/V and /E are optional.
Changes From V2.0:
==================
This version has three main changes from V2.0: 1) Support has been
added for the Panasonic (Matsushita) CD-ROM drive, 2) Various bug fixes,
and 3) Support for the ASWCDALL.SYS driver has been discontinued.
The bug fixes are itemized in detail below:
(1) Some drivers will reset the SCSI bus on power-up via an ASPI
generated "Bus Device Reset" message. The reset can be
avoided by adding a "/NORST" command line option.
(2) To support clone drives, each driver will no longer require
an "Inquiry" command be sent to verify the drive type. If
multiple drives are used, a "/I" command line option must be
added to force the driver to issue the Inquiry command, thereby
prohibiting clone usage.
(3) For SONY, on any command which requires playback status to be
returned, the driver more correctly updates its internal flags
to return the appropriate status. Previously, when the audio
status was returned (for the MSCDEX AUDST read IOCTL command),
sometimes the flags were not updated properly.
(4) Changes were made to correctly update the returned status info
in order to run under Windows with Multimedia Extensions.
