SYMPTOM
When users tried to load the CDROM.NLM, the following message was displayed
and the CDROM.NLM module failed to load:
MESSAGE
All of the system resources could not be assigned
SYMPTOM
The CD CHANGE command hung the server or forced the operating system into the
debugger. This only occurred in a few installations and Novell is aware of
the problem and is working on a solution. If the ASPICD.DSK driver is being
used contact Adaptec for an upgraded driver to address this problem. However,
see the below solution for an interim work-around.
SOLUTION
CD CHANGE work-around:
1. From the Server console, use the CD DISMOUNT command to dismount the
volume.
2. Load monitor and select DISK INFORMATION.
3. On the list of System Disk Drives, select the CD-ROM drive on which the
CD-ROM is to be changed.
4. Select Drive Operating Status, take the selection for Deactivate Drive.
5. Change the CD-ROM.
6. Select the Removable Drive Mount Status and take the selection for Mount
Drive.
7. Change back to the System Console and issue a CD MOUNT command.
SYMPTOM
Many CD-ROMs would not mount under the initial release of the CDROM.NLM. The
current version of the CDROM.NLM "S" supports a much broader range of CD's.
SOLUTION
Apply the CDROM3.EXE file.

Installation Instructions:
1. Rename the existing CDROM.NLM to *.OLD.
2. Copy the NWPA.NLM file (for NetWare 4.0x) or the NPA312.NLM file (for
NetWare 3.12) and the CDROM.NLM file to the SYS:SYSTEM subdirectory.
3. Load HBA driver (for example, AHA1540.DSK).
4. Load ASPICD.DSK or CDNASPI.DSK file if it is needed.
5. Based upon your version of NetWare use the following load statements:
NetWare 3.12 NetWare 4.x
Load AFTER311.NLM ------------
Load NPA312.NLM Load NWPA.NLM
Load CDROM.NLM Load CDROM.NLM
6. For a list of available CDROM.NLM commands, type CD HELP at the SYSTEM
CONSOLE prompt.
Solution Specifics:
----------------------------------------------------------------
CD DEVICE LIST typed at the console prompt yields the following information:
** CD ROM Device List
No. Act. Device Name Volume Name Mounted
2 Y Device # 0 SONY CD-ROM CDU-541 (8100000 NSEPRO Y
No.
--
Defines the Media Manager object number assigned to this particular CD player.
When you manipulate the CD in the player by using the "device number" this is
the number you should be using and NOT the number listed under "Device Name".
Act.
--
Indicates whether or not the device, cd player, is active.
Device Name
--
Indicates the name of the device as reported by the device. Do NOT use the
number that appears here to try and manipulate the CD. Using the above
example, you would type "CD MOUNT 2" to mount the CD. You would NOT type "CD
MOUNT 0".
Volume Name
--
Indicates the volume name as reported by the CD.
Mounted
--
Indicates whether or not the CD is mounted as a NetWare volume.
----------------------------------------------------------------
The files contained in CDROM3.EXE will only work with NetWare 3.12 and 4.0x.
Explanation of files:
NWPA.NLM
This is a support file for the CDROM.NLM running on a NetWare 4.0x server.
NPA312.NLM
This is a support file for the CDROM.NLM running on a NetWare 3.12 server.
CDROM.NLM
This is the updated CDROM.NLM only for Novell NetWare 3.12 and 4.0x.
NOTE: The current version of the CDROM.NLM needs to have AFTER311.NLM,
STREAMS.NLM and CLIB.NLM files loaded before it will load (this is only with
NetWare 3.12). You can accomplish this by loading the AFTER311.NLM file at
the server console. The CLIB.NLM and STREAMS.NLM files will be automatically
loaded. The "S" revision of the CDROM.NLM (included in this file) will not
use any previously created index files. An index file is created the first
time a new CD is mounted as a NetWare volume. Novell recommends that you
execute the CD PURGE command at the server console to purge all previous index
files. The CD PURGE command should only be executed when no CD's are mounted
as NetWare volumes. Executing the CD PURGE command requires that each CD
re-build its index files the first time it is mounted as a NetWare volume.
When mounting CDs with the new CDROM.NLM the /R parameter should be used to
rebuild the index files. This will result in a slight delay.
Issues Resolved:
1. Many CD-ROMs that would not mount under the initial release of the
CDROM.NLM will now mount without any problems. Enhancements were made to the
CDROM.NLM to better support the ISO 9660 and the High Sierra CD-ROM formats.
2. The error messages encountered during the mounting of a CD volume on a
NetWare 4.x server have been addressed.
3. CD-ROMs without a label will now mount. A new feature has been added so
that a volume label can be assigned to any CD volume upon mounting. Use the
following syntax:
CD RENAME /D=<device #> new name
CD MOUNT device#|volume name /R
NOTE:The "/R" must be used when remounting the renamed volume for the first
time.
NOTE:If CDROM.NLM encounters a CD-ROM without a label, it will automatically
assign a label to the CD that is associated with the CD device number.
4. The CDROM.NLM has been enhanced so that volumes are mounted based on a
64KB block size. It now takes less resources to mount a CD-ROM.
5. CDROM.NLM has been enhanced so that volumes mount faster. The CDROM.NLM
now correctly uses the data base files in the SYS:SYSTEM subdirectory.
6. Adding a name space to a CD volume is now possible. Novell recommends
using the /MAC and /NFS (these are CDROM.NLM command line parameters) for
these types of name spaces. For OS/2, you can use the ADD NAME SPACE command
to add this support to the CD volume.
7. The CDROM.NLM now supports CD's with greater than 1824 directories and
more than 58,368 files.
***************
*** WARNING ***
***************
DO NOT enable compression, suballocation, or change any of the file attributes
of the files contained on the CD-ROM or delete any of the files on the CD-ROM.
Undesirable results may occur. Novell recommends that only the
Supervisor/Admin be given rights to change the file attributes.
7. CD-ROM NLM Command Line Options:
CD DEVICE LIST
This command shows a listing of CD-ROM devices that are available on the
server, whether they are active, loaded CD-ROMs, and their mount status.
CD VOLUME LIST
This command shows a listing of all CD volumes that have been mounted since
the CDROM.NLM was loaded, the device that contains the CD-ROM, and the
CD-ROM's mount status.
CD MOUNT [No.] or [volume name] <flags>
This command mounts a CD-ROM as NetWare Volume. The available flags are
listed below. The [No.] or [volume name] can be obtained by using the CD
VOLUME LIST command.
CD DISMOUNT [No.] or [volume name]
This command dismounts a CD-ROM that has been mounted as a NetWare Volume. The
[No.] or [volume name] can be obtained by using the CD VOLUME LIST command.
CD CHANGE [No.] or [volume name] <flags>
This command is used to change a CD-ROM that is mounted as a NetWare volume to
another CD-ROM. Available flags are listed below. (See the note about CD
CHANGE in the SYMPTOM section of this document).
CD DIR [No.] [volume name]
This command is used to list the ROOT DIRECTORY contents of an UNMOUNTED CD.
CD GROUP ([group name] and [group num])
This command is used to show assigned groups and assign groups to a group
number 0 through 9. For example: Group "CDGROUP" needs to be assigned to the
CD group number 1. The syntax would be the following:
CD GROUP CDGROUP 1
NOTE: The "del" as the group name will remove a group number assignment.
The assignment could then be displayed by typing:
CD GROUP
The results would be as follows:
** CD ROM Access Group List
*Group: 0 > EVERYONE (assigned by default)
*Group: 1 > CDGROUP
To assign the group to a CD-ROM, see the available CD MOUNT flags below.
CD PURGE
This command will destroy all index files.
CD RENAME /D=[No.] [new volume name]
This command is used to change the name of a CD-ROM. The syntax is as
follows:
CD RENAME /D=<device #> new name
CD MOUNT device#|volume name /R
(NOTE: The "/R" must be used when remounting the volume.)
The [No.] or [volume name] can be obtained by using the CD VOLUME LIST
command.
CD HELP
This command displays the help screen for CDROM.NLM.
CD MOUNT and DISMOUNT FLAGS
■ The "/mac" is used to add Macintosh Name Space Support. This adds the
necessary DATA and RESOURCE forks so that Macintosh workstations can access
the information on the CD.
■ The "/nfs" is used to add NFS Name Space Support.
■ The "/G=x" is used to set the default volume group access rights. This is
used with the CD GROUP command previously listed. The mount syntax to assign
a group to a CD would be as follows:
CD MOUNT <device # | volume name> /G=x
where "x" is the group number assigned to a group. (See CD GROUP command
above).
■ The "/R" is used to rebuild the index file on the selected Volume.
NOTE: In previous releases, the /R option forced the CDROM.NLM to reuse an
index file if it existed. The CDROM.NLM now does this by default.
■ The "/X=name" is used to exclude a directory tree from the mounted volume
as the CD is being mounted.
■ Special option "/I": This option is used to ignore errors found with the
CD while attempting to mount the CD.
NOTE: Use of this flag could result in files not showing up after the CD
mounts.
■ The "/W" is used to mount a CD volume with the R/O attribute turned off.
With versions of the CDROM.NLM before v4.10g, the CD would be mounted with the
R/O option already disabled (that is, the CD would be mounted R/W). This
allowed the changing of file attributes, inherited rights masks, trustee
assignments and the adding of groups and users to a CD volume. If an attempt
is made, with 4.10g version of the CDROM.NLM, to change any of the above
items, an error writing to the CD will occur. To change the volume to R/W,
dismount the CD (CD Dismount <cd #| cd volume name> and remount it using the
"/W" option.
