Title: CDIS CDROM Driver and Access Server
Document #: FYI.S.27
Date: March 19, 1992
Product: Access Server
Product Version: 1.22
SUPERSEDES: NA
SYMPTOM: NA
ISSUE/PROBLEM
The use of CDROM players with Access Server.
SOLUTION
The CBIS "CD Solution v2.20C" (100-user), production date 2/10/92 is reported
to work with Access Server V1.2.
The configuration requirements are:
1. A CONFIG.SYS file for the REMOTE workstation as shown below. Note in
particular the LASTDRIVE statement. A LASTDRIVE statement must be inserted on
the Access Service as well and the drive specification must be identical to
that of the REMOTE workstation. Failure to do this will allow access to the
CD drives from the first session ONLY. A session will terminate normally but
upon reconnecting to the NAS, attempt to access the CD drives results in an
error message and the NAS must be rebooted.
FILES=30
BUFFERS=25
DEVICE=C:\CDSYS.SYS /D:MSCD001 /N:3
LASTDRIVE=H
2. A CONFIG.SYS for the Access Server is show below. Actual INCLUDE & EXCLUDE
statements will vary from environment to environment and are not relevant to
the CD Solution requirements. Note that the CDSYS.SYS driver is ahead of the
NASDISK.SYS drives. This is required for proper drive pointer allocation.
DEVICE=C:\ACCESS\QEMM386.SYS MAPS=32 HANDLES=64 RAM I=D000-DFFF X=C800-C9FF
DEVICE=C:\CDSYS.SYS /D:MSCD001 /N:3
DEVICE=C:\ACCESS\NASDISK.SYS /P18 /S
DEVICE=C:\ACCESS\NASDISK.SYS /P11 /S
FILES=5
BUFFERS=1
LASTDRIVE=H
STACKS 0,0
DEVICE=C:\ACCESS\LPTDRV.SYS
DEVICE=C:\ACCESS\STANDIO.SYS
SHELL=C:\COMMAND.COM /E:1024 /P
The following batch file is for the workstations locally on the network. They
will allow normal use of the CD ROM drives by individuals local to the LAN.
Note that you do not have to use a CDUSE command as the line MSCDEX /D:MSCD001
/L:E does this. The /L:nn is the start letter for the sequence of redirected
CD drives. In this case our first CD drive is E:. The /D:MSCD001 is the CD
device name from CBIS CD SERVER. This batch file accommodate IPX connections
to the NAS.
C:
CD\CBIS
MSCDEX /D:MSCD001 /L:E
CDFICHE
3. A batch file on the NAS's C: drive as shown below. Unfortunately, you must
allow users rights to access the NAS's local drives. This is accomplished by
inserting a /LD parameter on the %1:SIGNON line in the NASSTART.BAT file.
This potentially presents a security issue. Here we are using the CDREDIR and
CDUSE commands as MSCDEX will attempt to redirect to drive A:. CDUSE F: J:
will redirect the CD drive J: from the CD server to a local drive F:. The /O
parameter is critical as it allows an override to previous redirection. Not
including the /O parameter will cause the batch file to run properly the first
time, but subsequent attempts will result in an error message of duplicate
redirection. This batch file can be executed out of the LOGIN SCRIPT as EXIT
'CD.BAT'. It applies to users connecting to the NAS via the WNIM+ board. A
conditional IF..THEN statement is recommended.
@ECHO OFF
CDREDIR
CDUSE F: J: /O
CDUSE G: K: /O
CDUSE H: L: /O
CD\CBIS
CDFICHE
CD\
4. A modification of the DVINTF.CFG file in the \ACCESS directory as shown
below. DVINTF.CFG may or may not be created during NASGEN. It is a text file
and may be created using an ASCII text editor.
DEVICE=C:\CDSYS.SYS /D:MSCD001 /N:<number of active CD drives>
LASTDRIVE=L
MAX DV TASKS=<maximum number of active sessions allowed>
MAX BUFFER LENGTH=<packet buffer size, max=1536, default=512>
NOTE: This is not a certification. Further testing is still needed.
