 Additional Installation Guidelines

In some cases, just installing BackMaster and the drivers is insufficient to
run your tape drive properly.  With all of the different tape drives and
adapters available today, you may need to make some changes in your
configuration before you have a full installation.  This guide will help you to
determine if your system requires any modifications.

   2. Colorado Trakker Tape Drives

   3. Iomega Ditto & Conner Parallel Drives

   6. Older Tape Drives

   7. Warp Timing Issue's

Users With 8MB of RAM

If you are using a system with 8 megabytes of memory, there is an option during
installation for the Device driver memory enhancement.  If you do not check
this option, you may receive an Error 69 when attempting to use BackMaster.  To
eliminate this problem, you will need to edit the BackMaster tape drivers
located in your config.sys file.  At least one driver for BackMaster will not
begin with a REM statement.  On the drivers that do not begin with the REM
statement, add the /M option to the end of the driver.  The modified driver
should look like this:

DEVICE=C:\BACKMAST\PTDVR.SYS /M

C: will be the drive that you installed BackMaster on, and the BackMast
directory name should be the same unless you renamed the default directory. You
may have other drivers that you are loading for BackMaster, so be sure that you
include the /M option on all the drivers that you are using.

Colorado Trakker Tape Drives

Some systems will require you to make some minor modifications to BackMaster
configuration in order to use the Colorado Trakker drives properly.  The
systems that are most likely to require these modifications are those with
Pentium processors.  If you receive an Error #44, Error #117, Error #73, or
Error #70, increase the Control and Data delay options on the Parallel Page in
the BackMaster Configuration Notebook.  These values will increase to 6, and
will sometimes need to be set that high on some Pentium systems.  Setting these
values above 5 will result in a slight slowdown of the system until the tape
drive is initialized, which can take anywhere from 30 seconds to 2 minutes.


ΓòÉΓòÉΓòÉ <hidden> Iomega Ditto & Conner Parallel Drives ΓòÉΓòÉΓòÉ

Iomega Ditto & Conner Parallel Drives

Iomega and Conner have several new tape drives available on the market today
that have built in high speed adapters.  To use Iomega Ditto Easy 800 Parallel,
1700 Parallel, and 3200 Parallel, as well as Conner 800 Parallel, 1700
Parallel, and 3200 Parallel with BackMaster, you will need to edit your
config.sys by adding the /J1 option to the line that reads:

DEVICE=C:\BACKMAST\PTDVR.SYS

C: will be the drive that you installed BackMaster on, and the BackMast
directory should be the same unless you renamed the default directory. The
PTDVR.SYS driver will always have the same name.  You may have a /M after the
PTDVR.SYS if you are using only 8 megabytes of memory. Once you have located
the line, you will need to add a /J1 after the PTDVR.SYS.  If you have an
option added to the end of the driver already, add the /J1 after it.  The
modified driver line should look like this:

DEVICE=C:\BACKMAST\PTDVR.SYS /J1


ΓòÉΓòÉΓòÉ <hidden> Iomega Ditto Dash Accelerator and Conner CTC ΓòÉΓòÉΓòÉ

Iomega Ditto Dash Accelerator and Conner CTC

Iomega and Conner have released new adapter's called the Ditto Dash accelerator
card and the Conner CTC accelerator. If you are using one of these adapter's,
you will need to edit your config.sys by adding the /J1 option to the line that
reads:

DEVICE=C:\BACKMAST\FTDVR.SYS

C: will be the drive that you installed BackMaster on, and the BackMast
directory should be the same unless you renamed the default directory. The
FTDVR.SYS driver will always have the same name.  You may have a /M after the
FTDVR.SYS if you are using only 8 megabytes of memory. Once you have located
this line, you will need to add a /J1 after the FTDVR.SYS.  If you have an
option added to the end of the driver already, add the /J1 option after it.
The modified driver line should look like this:

DEVICE=C:\BACKMAST\FTDVR.SYS /J1

Tape Drives Attached to a Floppy Controller

Some systems with this configuration may encounter problems with Error #51 or
DMA Overruns, or even excessive shoeshining.  In these cases, you will need to
edit your config.sys by adding the /S option to the end of your BackMaster
drivers.  This will change the way BackMaster communicates with the drive and
should allow you to bypass these errors.  The driver should look like this:

DEVICE=C:\BACKMAST\FTDVR.SYS /S

C: will be the drive that you installed BackMaster on, and the BackMast
directory should be the same unless you changed the default directory. The
FTDVR.SYS driver will always have the same name.  If you have an option added
to the end of the driver already, then add the /S option after it.  You may
have other drivers that you are loading for BackMaster.  Be sure that you
include the /S option on all the drivers that you are using where you seem to
be having these errors.

Older Drives, Archive XL, CONNER, and MicroSolution

You May experience shoeshining when using some of the older Archive XL, Conner,
and MicroSolution drives.  To correct this error, you will need to edit your
config.sys and add the /J2 option to the end of your BackMaster drivers. The
driver should look like this:

DEVICE=C:\BACKMAST\FTDVR.SYS /J2

C: will be the drive that you installed BackMaster on, and the BackMast
directory should be the same unless you renamed the default directory. The
FTDVR.SYS driver will always have the same name.  If you have an option added
to the end of the driver already, then add the /J2 option after it. You may
have other drivers that you are loading for BackMaster.  Be sure that you
include the /J2 option on all the drivers that you are using.


ΓòÉΓòÉΓòÉ <hidden> Warp Timing Issues ΓòÉΓòÉΓòÉ

Warp Timing Issues:

OS/2 Warp is designed to require fewer resources and run in less memory. Some
of the default CONFIG.SYS statements in Warp's default installation are not
tuned for faster systems or all left out to allow the system to poll these
settings durring system usage. Because of this on some systems a timing issue
may cause BackMaster to have eratic results and error's. The following
CONFIG.SYS statements may improve over all system response as well as solving
some of BackMaster's eratic results.

PRIORITY_DISK_IO=YES - This is the default, it specifies that     applications
running in the foreground are to receive priority     for disk access over
applications running in the background.     PRIORITY_DISK_IO=NO specifies that all
applications (fore-     ground and background) are to be treated equally with
    regard to disk access. The default of YES can cause     BackMaster to have eratic
results due to swapper.dat file     growth, and other tasks that are running. To
specify that all     applications (foreground and background) are to be treated
    equally with regard to disk access, type the following in the     CONFIG.SYS
file: PRIORITY_DISK_IO=NO

MAXWAIT=3 - Says that if you're running more than one task at a time, none of
theose tasks can wait more than 3 seconds before its priority is boosted to
make it more likely to get control of the system. On some faster systems this
value is too long. Changing it to MAXWAIT=1 or 2, so no task has to wait so
long may make your system and BackMaster run more smoothly.

TIMESLICE=X,X - Sets the minimum and maximum amount of processor time allocated
to processes and programs for both OS/2 and DOS sessions. The DEFAULT is
dynamic time slicing based on the system load and paging activity. By default
this statement is missing from the Warp CONFIG.SYS file. Theoretically this
gives the best performance in all situations. By adding a TIMESLICE statement
to your CONFIG.SYS file you may achieve better system response and solve some
BackMaster problems. On many faster systems a statement of TIMESLICE=32.57
seems to speed up overall system performance and resolve some BackMaster
issues.

BASEDEV=PRINT01.SYS - Is the default parallel port driver for most systems, by
default the parallel irq value is polled durring system calls to any parallel
port devices. If you're parallel port device gives you eratic error's or
performance try using the BASEDEV=PRINT01.SYS /IRQ switch for the parallel port
driver statement.
