with the exception of the disaster recovery utilities. All other user
functions may be performed with data amounts up to 5 MB.
This demo may be freely copied and distributed, providing that this text file
is included with the demo. The user agrees, by the usage of this demo, to
accept full responsibility for the protection of their data. This demo is not
intended to be used as a final backup solution. MSR Development shall not be
held liable for any loss or damage, either actual or incidental, related to the
use of this demo.
_______________________________________________________________________________

About this demo:
See BMDEMO.DOC (located in the BackMaster program folder)
for more information.
Adaptec controllers:
If you have an Adaptec Busmaster controller, the following
CONFIG.SYS setting is suggested:
BASEDEV=AHA154X.ADD /V /A:0 /BON:4 /A:0 /BOFF:12
/V displays messages during bootup. /A:0 specifies the
first of four possible adapters, and is necessary even if
only one adapter is installed. /BON:4 sets the bus on time
to 4 microseconds. /BOFF:12 sets the bus off time to 12
microseconds. Most of this information may be found in the
Command Reference under BASEDEV. The above BASEDEV setting
gives the floppy controller enough time on the bus to
transfer enough data (by DMA) to keep the tape moving.
Special thanks to Beta Tester Jay Vanderbilt for this
information.
Bus timing and BackMaster DMA overrun error:
BackMaster may not work correctly if your system bus timing
is set higher than 8 MHZ. Tape drives are very sensitive to
hardware timing and an abnormal bus speed may result in
operational problems or errors reported by BackMaster.
If you are consistently getting a DMA overrun error message
(error number 51) we suggest checking your hardware settings.
Experiment with the bus speed, setting it as close to 8MHz
as possible. If your system supports the 7.15MHz or 7.25MHz
settings, these will usually work best.
CoreTape 250 tape drive support:
The BackMaster 1.1 release does not support the
CoreTape 250.
Creating recovery diskettes:
Now is a good time to create a set of custom recovery
diskettes for your computer. The recovery diskettes can
be used with a complete system backup to restore your
system or move your system to a new hard drive. BMRCVR
(in the BackMaster folder) will create the recovery
diskettes automatically. You may, if you wish, create
the recovery diskettes manually. Instructions for doing
so are given in the file BOOT.TXT, which is located in
the directory to which BackMaster was installed.
Device driver conflicts:
The BackMaster device drivers, FTDVR.SYS, TC15DVR.SYS, and
PTDVR.SYS, may on some systems have conflicts with the
Multimedia Presentation Manager (MMPM) drivers, some cdrom
device drivers, the Diamond P9000 video drivers, and ATI
Graphics Ultra video drivers. The driver conflicts may
cause an "Unable to open driver" error message or an OS/2
TRAP 000D. To avoid the driver conflicts, make sure that
FTDVR.SYS, TC15DVR.SYS, and PTDVR.SYS are loaded in
CONFIG.SYS after the CDROM drivers, Diamond P9000 video
drivers, and ATI Graphics Ultra video drivers, but before
the MMPM drivers.
Note: We recommend locating FTDVR.SYS and PTDVR.SYS
immediately following the IFS= statement (if present)
in CONFIG.SYS. However, some drivers (such as CDROM
drivers) may have to be loaded before our driver. Some
experimentation on your part may be required to find
the optimal location for FTDVR.SYS and PTDVR.SYS.
Concerning the Diamond P9000 video drivers: The driver
conflict with the P9000 and BackMaster drivers has been
known to cause OS/2 command windows to indefinitely
scroll, as if the enter key was continually pressed.
This symptom disappears when the video drivers are loaded
ahead of the BackMaster drivers.
Concerning the ATI Graphics Ultra video drivers:
Confilicts with these drivers are infrequent.
The BackMaster installation program, BMINST, will place the
FTDVR.SYS, TC15DVR.SYS, and PTDVR.SYS in the correct location
in CONFIG.SYS for most machines (except in the case of the
Diamond P9000 and ATI Graphics Ultra video drivers). The
driver conflicts are mentioned here for the case of a manual
installation or a driver conflict with specific systems.
Incompatibility with Colorado's TAPE.EXE 4.03 or greater:
BackMaster will not read compressed tapes made with any
version of TAPE.EXE 4.03 or greater, but BackMaster will
read the uncompressed volumes made with this software.
(This will be corrected in a future release.)
Low memory:
BackMaster may not work correctly on machines with less than
8 MB of memory. Machines with 8 MB of memory that have
network software loaded may also fall into this category.
In the case of a low memory machine, BackMaster will report
one of these errors: "Unable to load device driver", or
"Unable to allocate memory in device driver". Note: This
problem may be resolved in future versions of BackMaster or
OS/2.
Older tape drives (Hard Select):
The list of tape drives in the "Configuration Options"
dialog refer to Soft Select tape drives (most of the newer
tape drives are Soft Select), and will not correctly select
the older Hard Select type of tape drive. If you have a
Hard Select tape drive, select the "Generic QIC 40/80" tape
drive from the "Configuration Options" list. Refer to the
documentation that came with your tape drive to determine
which type of tape drive (Hard Select or Soft Select) you
have. In general, Hard Select drives may have jumpers to
select the drive (A or B) and will only function as the A or
B device, but not as a third floppy device.
Ordering information:
See ORDERFRM.TXT (located in the BackMaster desktop folder)
for more information.
Stacker and DCF2:
If FTDVR.SYS (or PTDVR.SYS) resides on a stacked volume,
the DEVICE=FTDVR.SYS statement should be placed after the
Stacker device drivers. Some conflicts have been reported
when BackMaster accesses files in a DCF2 Virtual Disk Unit,
resulting in a SYS3175 in DOSCALL1. If you encounter this
problem, please report it to Proportional Software.
TC-15M high-speed adapter:
BackMaster supports the TC-15 high-speed adapter, but does
not support the TC-15M high-speed adapter, which is the
microchannel version of the TC-15. (Please consult MSR
for the latest information)
Time critical:
During normal tape drive operations, BackMaster must respond
to the tape drive signals within a certain amount of time,
or the tape drive may start to behave unpredictably, causing
BackMaster to abort the current tape operation. Active DOS
and Windows sessions may deny BackMaster the CPU time needed
to respond quickly to tape drive signals. If BackMaster
aborts in the middle of a tape operation, make sure that the
"Time Critical" check box in the "Device" page of the
configuration notebook is checked before retrying the tape
operation. Time critical will ensure that BackMaster is
given enough CPU time to respond quickly to the tape drive
requests.
Version of OS/2:
BackMaster is designed for OS/2 versions 2.1 and above. It
may be used with OS/2 2.0, but unexplained failures (ie. BackMaster
may abort and close without warning due to a PM bug) may occur,
especially during the file selection process. If you must
use BackMaster with OS/2 2.0, we suggest that you avoid
extensive use of the PM interface. (ie. use command line options
where possible)
Write errors:
Write errors during a backup are fatal. If BackMaster
detects a write error, it will report the error and abort
the backup. It will be necessary to reformat the tape
before making further backups, since version 1.1 of
BackMaster will not update the bad sector map if bad sectors
are found during a backup.
