Option Board Version 3.0 (and up) Notes:
======================================

A feature has been added to the Option Board software that may
be new to you if you are updating from a previous release:

This new feature will allow single drive users to make backups
without disk-swaps if they have a hard disk or RAM disk with 
enough unused space.

Here is how it works:

If you have a hard disk (or large RAM disk) and make backups on 
an XT or AT computer with only a single 360 K drive, the first
part of the disk will be read into the computer's memory.  The
remainder of the disk will be read into a temporary file TC
will create on your hard disk (or RAM disk).  When TC asks you
to insert the target disk, it will write the first part of the
disk from the computer's memory, then retrieve the rest of the
disk data from the temporary hard disk (or RAM disk) file it
created while reading the original disk.  When the backup copy
is complete, the temporary hard disk file will be erased.

This all happens automatically - there is nothing you need to
do.  Just select the source and target drives like usual
(e.g. source as drive A and target as A or source as B and 
target as B).  You do not directly specify the hard disk -
TC will find it automatically.

This hard disk buffering only happens if the source drive and
the target drive are the same. If you make a backup from drive
A to B, for example, the hard disk will not be used.

Please note that this does not mean the Option Board can copy
protected software to a hard disk.  It only uses the hard disk
to minimize disk swaps for customers with a single floppy disk.


If You Have Problems:
--------------------

We have had some reports that certain non-standard hard disks
and RAM disk drivers can interfere with the disk-buffering
capabilities of TC version 3.0 and up. If you notice that TC
seems to "hang" after you enter the target drive or otherwise
will not make a good backup, please use the file "TCS" instead
of "TC" (it is on this diskette).  TCS is identical to TC 
except that it does not have the hard disk buffering feature.

Thank you for using the Copy II PC Option Board.


A NOTE FOR AUTOLOADER USERS:
----------------------------

The file names have been changed for the autoloader versions
of the Option Board software.  The new name of "TCMTN" is
"TCLOADER" and the new name of "TCMAN" is "TCMANUAL".  These
files are for software duplication firms who wish to use the
Option Board as part of a low-cost disk duplication system
and require extra hardware not included with the Option Board.
