dosfloppy(CDMT)

Description

To install a product from a single DOS floppy, first generate the distribution image using either the Software Mastering Toolkit (SMT) or the Custom Distribution Mastering Toolkit (CDMT), then copy the custom-installable image to an existing DOS floppy filesystem and use custom to install it.

The custom utility supports all standard installation features for a product distributed on a DOS filesystem floppy, with the restriction that the distribution size be smaller than a single floppy. Only one image per product is supported and the image must fit on a single floppy volume.

You should be familiar with the concepts and tools required to cut custom-installable distributions on media other than DOS floppies.

To cut, create, and install a custom-installable product on a DOS floppy:

1. Use the distribution mastering tools to cut the custom-installable distribution image:

   
   Software Mastering Toolkit

   For a perms(F) list-based product, use the SMT to cut the distribution image. See the Software Mastering Toolkit Guide for details.

   Given the desired floppy device and media size, the mkcuts(SMT) utility generates enough media-sized tar(C) images to contain the entire distribution. Because the SMT-generated images are padded to the specified media size (for example, 1.44MB), you must use tar to extract the files from the generated image into a directory. You can then use tar to re-archive the directory into a new nonpadded product image to copy to the DOS floppy.

   
   Custom Distribution Mastering Toolkit

   For a Software Storage Object (SSO)-based distribution, use the CDMT. See ``Custom Distribution Mastering Toolkit'' in Developer's Topics. CDMT generates a cpio(C) archive image.

   NOTE: If more than one image is generated, the product is too large to use the DOS floppy distribution feature.

2. Format the DOS floppy using either the format command from DOS or the dosformat(C) command from your SCO OpenServer system:
   
   dosformat /dev/fd0

3. Create a directory called /SCO in the DOS filesystem. To create the directory on the DOS floppy, use either the mkdir command from DOS or the dosmkdir(C) command from your SCO OpenServer system:
   
   dosmkdir /dev/fd0:/SCO

4. Copy the single-volume media image that you generated using the mastering tools onto the DOS floppy as /SCO/CUSTOM.DST. Use the doscp(C) command from your SCO OpenServer system to copy the image:
   
   doscp /SCO/CUSTOM.DST /dev/fd0:/SCO/CUSTOM.DST

Use one of the following methods to install the product:

Install from the command line:

1. Insert the floppy into the floppy drive.

2. Enter:
   
   custom -p product_name -i -m floppy_device

Install using the Software manager:

1. In the Software manager, select Run Installation from the Software menu.

2. Insert the floppy disk into a drive and select that device from the menu.

3. Click on Full.

Limitations

• custom only recognizes a single distribution archive named /SCO/CUSTOM.DST on a DOS floppy.

• The /SCO/CUSTOM.DST distribution image must be a valid tar or cpio archive.

• The custom-installable image must fit a single floppy volume.

• The DOS commands, doscp(C) and dosdir(C), must exist on the target SCO OpenServer system in the /usr/bin directory. Make sure that these utilities have been installed.

• The DOS floppy must be formatted with DOS version 5.0 or earlier.
