Configuring a CD-ROM on a Stacked System
(Applies to Stacker 1.x, 2.x, and 3.0)


Background
During system startup, Stacker drives are assigned a drive letter by DOS as
they are "mounted" by the Stacker device driver in Config.sys. CD-ROM drives
are not assigned a drive letter until MSCDEX.exe loads in the Autoexec.bat
file. Because Stacker drive letters are assigned first, the CD-ROM will have
to take the next available letter. This means that if your CD-ROM existed
before Stacker, you will probably have to re-configure it to use a new drive
letter.

Configuring the CD-ROM.

1. CONFIG.SYS - Here are is a sample Config.sys. It is recommended that
the CD-ROM device be loaded after SSWAP.COM as shown.

DEVICE=C:\DOS\SETVER.EXE (this is required if running under DOS 5.0)
DEVICE=C:\STACKER\STACKER.COM C:\STACVOL.DSK .....etc.
DEVICE=C:\STACKER\SSWAP.COM C:\STACVOL.DSK /SYNC
DEVICE=SONYCDU.SYS or DEVICE=PCD650S.SYS [/D:name /B:xxx /M:mode]

2. AUTOEXEC.BAT The CD-ROM letter is assigned here with the /L: parameter
on the MSCDEX command line. Take note of the Stacker drive letter
assignments at boot time. For example, to determine which drive letters
Stacker has been given, type:

C:\STACKER\STACKER

The output will look similar to:

STACKER - 2.00, (c) 1990-91, Stac Electronics, Carlsbad, CA
Drive C: was drive D: at boot time [ D:\STACVOL.DSK ]
Drive D: was drive C: at boot time

Set the CD-ROM to the next available drive letter. In this example, drive
E: is available for the CD-ROM. In Autoexec.bat you would assign drive E:
on the MSCDEX command line,

MSCDEX /D:name /M:x /V /L:letter /E
Change /L:Letter to /L:E
MSCDEX /D:name /M:x /V /L:E /E

After changing the CD-ROM drive letter, it may be necessary to re-setup
applications or programs to recognize the new drive letter designation.
