Chapter 2
How to back up your new Video-Voice Original Master, and
How to create a Video-Voice Work Disk.
How to use this chapter:
If are using a computer with two floppy disk drives, read
parts A through E, and follow the instructions in those parts.
If are using a computer with a hard disk drive and one
floppy disk drive, read parts A through E, but do not perform any
of the instructions. Follow the instructions in part F instead.
If are using a computer with no hard disk and only one
floppy disk drive, read parts A through E, but do not perform any
of the instructions. Skip over part F, and follow the
instructions in part G instead.
A. Protect your investment!
Before you use Video-Voice, follow these simple
instructions to protect your investment. Disks are fragile, but
it is easy to copy the data on them, so please take the time to
make backup copies of this valuable program. Be careful, but
don't panic if you make a mistake. Copying disks with a computer
is similar to using a high-speed cassette duplicator, but a whole
lot faster.
B. What you will do:
1. You will create a Video-Voice Working Master disk. You will
keep your Video-Voice Working Master disk close at hand and use
it for creating Video-Voice Work Disks. You will store the
Original Master disk in a safe place
2. You will create a bootable System Disk.
3. You will create a bootable Video-Voice Work Disk. You will use
this disk each time you use the Video-Voice program.
C. How to create a Video-Voice Working Master disk:
You are going to make a back-up of the Video-Voice disk that
you received from Grassroots Computing.
While you are making the backup disk, YOUR COMPUTER IS NOT
GOING TO TALK, even if your synthesizer is connected. If you
have never used a computer before, seriously consider getting a
more knowledgeable friend to help you with these steps. Later
on, Video-Voice will enable you to use your computer
independently.
To make a Video-Voice Working Master disk, you will need the
Video-Voice program disk you bought from Grassroots Computing, a
disk with your computer's DOS (Disk Operating System) on it, and
a blank disk. Be sure that your DOS disk has the DISKCOPY
command file on it.
1. How to boot your computer. Place your DOS disk in disk
drive A. If your disk drives are mounted horizontally, insert
your disk with the LABEL FACING UP and with the notch to the
left. If your disk drives are mounted vertically, follow the
manufacturer's instructions for inserting disk. Close the drive
door. Now turn on the computer. Wait for the machine to warm up
and come up to full speed. This is called "booting the
computer." This "booting" process can take as long as two minutes
on an IBM PC. As it boots, the computer may beep but that's a
normal sound. The disk drive will whir and make grinding sounds.
The computer is loading the DOS program from drive A into its
memory. Eventually the drive noises will cease.
The computer will prompt you to enter the date. It does
this by displaying a message on the screen and waiting for you to
type in the date. Your synthesizer will not tell you about this
prompt. Just press the ENTER key to bypass it.
The computer will prompt you to enter the time. Bypass the
prompt by pressing the ENTER key.
The computer will display the "A>" prompt. This is an
upper-case "A" followed by a ">" symbol (known as a "greater
than" sign or a "right angle bracket"). The "A>" prompt is the
computer's way of telling you it is ready for you to type a
command.
2. IF YOU HAVE A COMPUTER WITH TWO FLOPPY DRIVES, type the following
line of text on your keyboard:
DISKCOPY A: B:
then press the ENTER key. Type it in EXACTLY as it is shown
above. If you enter any character incorrectly, you could destroy
data on one of your disks. DISKCOPY is a program on your DOS
disk. It will prompt you to place disks in drives A and B.
3. Take your DOS disk out of the A drive and put it away.
4. Make sure that the Video-Voice disk you received from
Grassroots Computing has a write protect tab on it, then place it
in drive A. This is your "Original Master."
5. Place a blank disk in Drive B. This will soon be your
"Working Master."
6. Close the drive doors and press the ENTER key to tell the
computer to begin duplicating your Video-Voice Original Master
onto the disk in drive B.
7. When the drives stop whirring, you will be asked if you
want to make another copy. Press the N key, followed by the
ENTER key.
8. Remove your new Working Master copy of Video-Voice from
drive B. Put an identifying label and a write-protect tab on it,
and place it in its protective sleeve.
9. Remove the Original Master copy of Video-Voice from drive A,
place it in its protective sleeve and store it somewhere safe.
We strongly suggest that you store your Original Master in
another building, such as your mother's house or a friend's
apartment. That protects you against (heaven forbid) loss of the
program by fire, theft, or other disaster.
(note: Grassroots Computing will charge its usual upgrade fee to
replace a damaged or missing original master.)
D. How to format a System Disk:
You will need a bootable System Disk in order to create a
bootable Video-Voice Work Disk.
To make a bootable System Disk, you will need your DOS disk
and a blank disk.
1. Put your DOS disk in drive A and close the drive door.
2. Put your blank disk in drive B and close the drive door.
3. Type the following line of text on your keyboard:
FORMAT B:/S
then press the ENTER key. Type it in EXACTLY as shown above. If
you enter any character incorrectly, YOU COULD DESTROY DATA on
one of your disks. The computer will prompt you to place a disk
in drive B. You have already done so, so just press the ENTER
key.
4. When the drives stop whirring, you will be asked if you want
to format another copy. Press the N key, followed by the ENTER
key.
5. Remove the DOS disk from drive A and put it away.
6. Remove the bootable System Disk from drive B, put it in its
protective sleeve, and keep it handy for the next step.
E. How to create a bootable Video-Voice Work Disk:
You will need the Work Master disk you created a few steps
back, and the bootable System Disk you just created.
1. Place your Video-Voice Working Master in Drive A and close
the drive door.
2. Type in the command:
COPY A:*.* B:/V
then press the ENTER key. The drives will whir for a while and
the names of the files that have been copied will appear on the
screen.
3. When the drives stop whirring, remove the Video-Voice Working
Master disk from drive A and put it away. You will only use the
Working Master to make new Video-Voice Work Disks.
4. Remove your new Video-Voice Work Disk from drive B, put a
label and a write-protect tab on it, and place it in its
protective sleeve. You will use your Video-Voice Work Disk to
load Video-Voice into the computer on a daily basis.
Anytime you want to make another Video-Voice Work Disk, format
another bootable System Disk use the Video-Voice Working Master
to make another copy.
F. Setting up Video-Voice on a hard disk:
As a user of a computer with a hard disk drive, you do not
need to make a Working Master disk or a Work Disk. Instead, you
will copy the Video-Voice files into a sub-directory on your hard
disk. Then you will store your Video-Voice Original Master disk
in a safe place. You will run Video-Voice from your hard disk.
1. Boot your computer. Press the ENTER key twice to bypass
the date and time prompts. If you have a multifunction board
with a real-time clock-calendar on it. The correct time will be
loaded automatically and there are no date and time prompts to
bypass.
A "C>" prompt will be displayed. If your hard drive is
designated as anything other that "C:" drive, use the correct
designation whenever you are instructed to enter "C:".
2. Type the following line of text on your keyboard:
MD VIDVOICE
and press the ENTER key. Type it exactly as shown above. You
have just created a new subdirectory on your hard disk called
VIDVOICE.
3. Type the following line of text on your keyboard:
CD VIDVOICE
and press the ENTER key. Type it exactly as shown above. You
have just made the VIDVOICE subdirectory the default
subdirectory.
4. You will copy the contents of the Video-Voice Original
Master Disk into the VIDVOICE subdirectory.
Place the Video-Voice Original Master disk that you bought
from Grassroots Computing in Drive A. Close the drive door.
Type the following line of text on your keyboard:
COPY A:*.* C:/V
and press the ENTER key. Type it exactly as shown above. The
drives will whir for a while and the names of the files that have
been copied will appear on the screen.
When the drives stop whirring, all of the files that were on
the Video-Voice Original Work disk will also be in the VIDVOICE
subdirectory of your hard disk.
6. Type the following line of text on your keyboard:
CD/
and press the ENTER key. You have just made the "root" directory
of your hard disk the default directory.
7. Type the following line of text on your keyboard:
COPY A:HARDVV.BAT C:/V
and press the ENTER key. Type it exactly as shown above. The
drives will whir for a while and the name of the file that has
just been copied will appear on the screen.
When the drives stop whirring, the batch file HARDVV.BAT that
was on the Video-Voice Original Work disk will also be in the
root directory of your hard disk.
8. Type the following line of text on your keyboard:
REN HARDVV.BAT VV.BAT
and press the ENTER key. Type it exactly as shown above. The
drives will whir for a while.
When the drives stop whirring, the batch file HARDVV.BAT that
was on the Video-Voice Original Work disk will have been renamed
as VV.BAT in the root directory of your hard disk.
9. Remove the Video-Voice Original Master disk from drive A and
store it in a safe place.
G. Backing up and making work disks on a single-drive computer:
If you have access to a computer with two disk drives, make
your back-up copies and your work disks on that machine if you
can. It will be MUCH EASIER ON A TWO-DRIVE MACHINE.
If you are using a computer with only one disk drive, please
SERIOUSLY CONSIDER UPGRADING the computer to two disk drives. It
will make your computing far more satisfying, and will greatly
reduce the frustrations and inevitable mistakes that seem to be
part of using a single-drive computer.
If you have no alternative but to use a computer with only
one disk drive, follow the instructions CAREFULLY. Sighted
assistance or a device like the Opticon will be necessary to read
the screen.
1. Boot your computer. Press the ENTER key twice to bypass the
date and time prompts.
2. Insert your DOS disk in the drive, and close the drive door.
Type the following command on the keyboard:
FORMAT A:/S
then press the ENTER key. Type it EXACTLY as shown above. The
drive will whir for a short time.
3. When the whirring stops, remove the DOS disk from the drive,
and insert a blank disk in the drive and close the door. Press
the ENTER key. The drive will whir and grind for a while,
pausing occasionally for short times.
When the drive has stopped, remove the newly formatted disk
and put it aside temporarily.
4. Insert another blank disk and close the drive door. Press
the Y key. This instructs the computer to format another disk.
As before, the drive will whir and grind and eventually come to a
stop.
When the drive has stopped, press the N key. This instructs
the computer to NOT to format another disk.
Remove the newly formatted disk and put it aside
temporarily. You now have two bootable system disks.
5. DO NOT ATTEMPT TO PERFORM THIS STEP WITHOUT A MEANS OF
REVEIWING THE SCREEN DISPLAY.
Because of the high probability of error involved in this copying
technique, it is very important that the disk being copied from
MUST have a write-protect tab in place.
First you will make a Video-Voice Working Master disk.
Make sure that the Video-Voice Original Master disk that you
received from Grassroots Computing has a write protect tab on it,
then insert it into the disk drive and close the drive door.
Type the following line of text on your keyboard:
COPY A:*.* B:/V
then press the ENTER key.
The drive will whir for a while. The computer is making a
copy of PART of a disk file in its RAM memory. A message will be
displayed on the screen to insert the disk for drive B.
On a single-drive machine, the computer "pretends" that it
has two drives, but requires the user to physically insert and
remove disks. As far as the computer is concerned, the Original
Master disk is on pretend-drive A. The copy that you are going
to make will be on pretend-drive B. So --
Remove the Original Master disk from the drive (pretend-
drive A) and insert the blank disk into the drive (pretend-drive
B) and press the ENTER. The drive will whir for a while. It is
making a copy of the part of the disk file that is in its RAM
memory and putting the copy on the disk on pretend-drive B. A
message will be displayed on the screen to insert the disk for
drive A.
Remove the Working Master disk from the drive (pretend-drive
B) and insert the Original Master disk into the drive (pretend-
drive A) and press the ENTER key. The computer will whir for a
while and display the message to insert the disk for drive B.
Remove the Original Master disk from the drive (pretend-drive
A) and insert the Working Master disk into the drive (pretend-
drive B) and press the ENTER key. The computer will whir for a
while and display the message to insert the disk for drive A.
Continue removing and inserting disks until the computer
displays the A> prompt again. Remember at all times that the
Video-Voice ORIGINAL Master disk goes on pretend-drive A and that
the Video-Voice WORKING Master disk goes on pretend-drive B.
When the computer displays the A> prompt, you are finished
making the Working Master copy from the drive and put it aside.
Remove the Video-Voice Original Master disk, place it in its
protective sleeve, and store it in a safe place.
Remove the Video-Voice Working Master, put a label and a
write-protect tab on it, place it in its protective sleeve, and
set it aside temporarily.
6. DO NOT ATTEMPT TO PERFORM THIS STEP WITHOUT A MEANS OF
REVEIWING THE SCREEN DISPLAY.
Because of the high probability of error involved in this copying
technique, it is very important that the disk being copied from
MUST have a write-protect tab in place.
Now you will make a Video-Voice Work disk.
Insert the Video-Voice Working Master disk that you just
made in the drive.
Type the following line of text on your keyboard:
COPY A:*.* B:/V
then press the ENTER key.
Repeat the disk-swapping procedure you performed when making
the Working Master disk. The Working Master disk now goes on
pretend-drive A and the new blank disk goes on pretend-drive B.
When the computer displays the A> prompt, you are finished
making the Video-Voice Work disk. Remove it from the drive and
put a label and a write protect tab on it, and place it in its
protective sleeve. You will use your Video-Voice Work disk to
load Video-Voice into the computer on a daily basis. Take the
Video-Voice Work Master disk, place it in its protective sleeve,
and store it in a safe place. Use the Work Master Disk to make
any more Video-Voice Work Disks. Do not use the Video-Voice
Original Master disk except to make another Video-Voice Working
Master disk.
