|
|
<p>To create a new disk image,
|
|
all you have to do is tell AppleWin to use an image file which doesn't
|
|
already exist and the emulator will automatically create a new image
|
|
file. Specifying a new disk image is like inserting a blank,
|
|
unformatted floppy disk into a real drive. This means that
|
|
the image must be formatted by emulator before it can be used.
|
|
Specifically, this is what you'd do using DOS 3.3:</p>
|
|
|
|
<ol>
|
|
|
|
<li>Load a master DOS 3.3 disk
|
|
image in drive 1 and boot the emulated Apple. </li>
|
|
|
|
<li>Click on the Drive 1
|
|
toolbar button. </li>
|
|
|
|
<li>Instead of selecting a disk
|
|
image from the list, type in a name for a new disk image and press
|
|
enter. </li>
|
|
|
|
<li>Type in a program that you
|
|
want DOS to run whenever this new disk is booted. A simple but useful
|
|
program is:<br>
|
|
|
|
<br>
|
|
|
|
<span style="font-family: Courier New,Courier,monospace;">10
|
|
PRINT
|
|
CHR$(4);"CATALOG"</span><font face="Courier New"><br>
|
|
|
|
</font><br>
|
|
|
|
</li>
|
|
|
|
<li>Type <span style="font-family: Courier New,Courier,monospace;">"INIT
|
|
HELLO"</span> to initialize (format) the disk image. </li>
|
|
|
|
</ol>
|
|
|
|
<p>You now have a working disk
|
|
image, which you can use to save documents or other information. If you
|
|
want to fill this image with data from a real floppy disk that you
|
|
have, then you need to "transfer" the disk's data. See the <a href="ddi-transfer.html">Transferring
|
|
Disk Images</a> topic for more information. </p>
|
|
|
|
<p>Please note that not all disk image types supported by
|
|
AppleWin can be created in this manner. Since there is no way
|
|
to detect the image type from the image itself, it is determined by the
|
|
given file extension only. Three extensions are allowed: (.DSK, .DO,
|
|
.NIB). The first two create a "DOS Order Image" and then latter creates
|
|
a "Nibble Image". If the extension is completely omitted,
|
|
".DSK" will be chosen by default. For more information, see <a href="ddi-formats.html">Disk Image Formats</a>.</p>
