TECHNICAL BULLETIN
2.26.90 PCTOOLS5 JCR (update 7.17.90)
DISK UTILITY SOFTWARE: PC Tools Deluxe 5.5, Central Point Software
Installing PC Tools
PC Tools can be installed on a server and shared across the network by the workstations. Using
this configuration, however, an environment variable must be set to specify where PC Tools
should put all user-specific files (PCSHELL.THM, PCSHELL.CFG, PCBACKUP.CFG, etc). This
needs to be a directory that is unique for each user and to which the user has write privileges.
This variable should be added to the workstation's autoexec.bat.....
SET PCTOOLS = drive: \path
Where drive is the drive letter and path is the full path where PC Tools should place its user-
specific files. All of the currently linked network drives will show up with the local drives on the
Drive Command Line. This will show only the active links.
NOTE: The customer must purchase a copy of PC Tools Deluxe for every station on the network
or contact Central Point for a Network or Site License.
The compatibility testing was processed on a 3-node network. PC Tools was installed/configured
on a common server (with environment variables set) during one set of tests, and again on all
3 nodes (without environment variables) during a second set of tests. The systems were running
DOS 3.3 and DOS 4.01. I selected to load PC Cache, Mirror, PCShell and Desktop memory
resident. PC TOOLS then made the following adjustments to the autoexec.bat file:
MIRROR C: /TC {To activate Mirror on drive C:
PC-CACHE /IA /IB {Activates PC Cache
PCSHELL /RT {To load PCShell TSR
DESKTOP /R /CS {To load Desktop resident, uses 42064 bytes
PC BACKUP
The command to load PC Backup is PCBACKUP - for a listing of configurations switches, please
refer to the PC Tools Hard Disk Backup manual (p 6).
PC Backup does provide attribute exclusion / inclusion by configuration through the Options
menu. PC Backup will backup all hidden/system/read only files when configured to do so; the
default configuration does not backup hidden or system files. It will not backup the QCONTROL
file in LANtastic. PCBackup will backup files onto and from a redirected drive with no problems.
FILE AND DISK RECOVERY
The following commands in PC TOOLS are not compatible with a network environment:
Compress, Rebuild, Mirror, Undelete. These commands handle direct physical access to the
drive, which is not possible on a network drive.
PC SHELL
The following commands in PCSHELL are not available on a network server or a network drive:
Directory Maintenance, Prune and Graft, Directory Sort, Disk Info, Disk Map, File Map, Rename
Volume, Search Disk, Undelete, Verify Disk, View/Edit Disk (Sector Editor).
To print from PCSHELL, a Ctrl-Alt-PrtScrn is required.
PC SHELL may be loaded in shell mode by typing PCSHELL at the prompt, or it may be loaded
in TSR mode. PC Shell uses EMS (Expanded Memory) when it is resident and active only.
When you hotkey into PC Shell, it will automatically load the PCSHELL.THM overlay file into
expanded memory (LIM compatible), if available, to hold the image of the underlying application.
If EMS memory is insufficient or non-existent, then the image is placed in PCSHELL.THM on disk.
The amount of expanded memory required to run PCShell depends on how PCShell is loaded.
If one loads PCShell with the TINY configuration (recommended), it will require approx 200KB of
expanded memory.
To remove from memory, type KILL (Note: This will remove PCShell, Desktop and BackTalk if
they are the last TSR utilities to be loaded).
When PC Shell is loaded in TSR mode, a configuration switch is required to determine the
amount of memory PC Shell will take up. To load in TSR mode, select one of the following -
additional switches are available to provide support for various configurations. For a list of those
switches, please refer to the PC Tools Data Recovery and DOS Utilities manual. Don't forget to
load this after the network! The hotkey to load PC Shell is Ctrl-Esc.
PCSHELL /RTINY - Uses 9K (recommended configuration)
PCSHELL /RSMALL- Uses 70K
PCSHELL /RMEDIUM- Uses 90K
PCSHELL /RLARGE- Uses 170K
NOTE: PC Shell will work with different versions of DOS across the network. For example, one server can
run DOS 3.3 while another runs DOS 4.01. PC Shell can access files on both across the network.
DESKTOP MANAGER
The Desktop Manager can be loaded stand alone by typing DESKTOP at the prompt. It can also
be loaded in TSR mode, by adding the /R switch and typing in DESKTOP /R. The hot key to load
Desktop is Ctrl-Space. Just like PC Shell, Desktop uses EMS when it is resident and active only.
It will load the DESKTOP.THM overlay file into expanded memory.
To remove from memory, type KILL (Note: This will remove PCShell, Desktop and BackTalk, if
they are the last TSR utilities loaded).
Other switches are available to support various configurations. For a detailed list, please refer
to the PC TOOLS Desktop Manager manual (pp 14).
PC SECURE
NOTE: Due to USA federal regulations, PC Secure is shipped out of the U.S.A. with the
encryption/decryption option disabled. The U.S.A. and non-U.S.A. versions of PC Secure are not
compatible. You will NOT be able to decrypt a file with the U.S.A. version that was compressed
with the non-U.S.A. version and vice-versa. PC Secure does work with the network. However,
it's suggested never to place your decrypted files on a file server. Always copy the encrypted
file to a private directory or local disk first, then decrypt it. For a list of configuration switches on
PCSECURE, please refer to the PC Tools Data Recovery and DOS Utilities manual (p 197).
PC-CACHE
PC-Cache should be installed after Mirror but before any other memory-resident programs.
During one set of these tests, PC-Cache was loaded in the 640K memory and no problems were
encountered. Due to various reports by our distributors and dealers indicating the product to
be compatible, no further testing was done at this time. For a listing of configuration switches,
please refer to the PC Tools Data Recovery and DOS Utilities manual (p 170).
To remove PC-Cache from memory, type PC-CACHE /UNLOAD.
