Creating SCO OpenServer floppy media

This section describes how to create a floppy disk from the floppy images provided on the SCO OpenServer CD-ROM, including the floppy Boot Disk, small kernel Boot Disk, and the two BTLD disk images.

• To create a floppy disk on an SCO OpenServer system or other UNIX system, see ``Creating floppy disks on UNIX systems using ezcp''.

• To create a floppy disk on a Windows or DOS system, see ``Creating floppy disks on Windows systems using ezcp''.

Creating floppy disks on UNIX systems using ezcp

If you are using the first 3.5-inch floppy drive on your system to create an SCO OpenServer floppy disk, we recommend that you use the ezcp command, as described in this section.

The ezcp command is a UNIX shell script that copies images to /dev/rfd0135ds18. This script is provided on the SCO OpenServer System CD-ROM, in the /images directory.

To create an SCO OpenServer floppy disk on a UNIX system using the ezcp command:

1. Format a 3.5-inch high density floppy disk using the format(C) command. Label the floppy disk appropriately.

2. Use the mount(ADM) command to mount the SCO OpenServer System CD-ROM to the /mnt directory or other desired mount point.

3. Change to the /images directory on the SCO OpenServer CD-ROM:
   
   cd /mnt/images

   If you are using a different mount point, substitute it for /mnt in the above example.
   

4. Use the ezcp command to copy the desired image to the floppy disk:
   
   ezcp boot/image_name

   where image_name is one of the following image files:

   	install.img	primary floppy Boot Disk
   	smallmem.img	small kernel Boot Disk
   	btld.img	first Boot-Time Loadable Drivers disk
   	btld2.img	second Boot-Time Loadable Drivers disk

5. Verify that the image was written to the floppy disk correctly using the sum(C) command:
   
   sum -r /dev/fd0

   Compare the result to the checksum file on the SCO OpenServer CD-ROM (/images/boot/image_name.sum) that corresponds to the image you copied. If the checksums are the same, the floppy disk is ready for use.

   ---

   NOTE: Depending on the version of your operating system and the configuration of your hardware, you may use a device node other than /dev/fd0.

Alternative method for creating floppy disks on UNIX systems

If you are unable to use the ezcp command on your UNIX system to create an SCO OpenServer floppy disk because you need to use a drive other than the first 3.5-inch floppy drive, use this approach instead:

1. Format a 3.5-inch high density floppy disk using the format(C) command. Label the floppy disk appropriately.

2. Use the mount(ADM) command to mount the SCO OpenServer System CD-ROM to the /mnt directory or other desired mount point.

3. Change to the directory on the SCO OpenServer CD-ROM that contains the disk images:
   
   cd /mnt/images/boot

   If you are using a different mount point, substitute it for /mnt in the above example.
   

4. Copy the desired image to the floppy disk using the dd(C) command:
   
   dd if=image_name of=/dev/fd0 bs=18k

   where image_name is one of the following image files:

   	install.img	primary floppy Boot Disk
   	smallmem.img	small kernel Boot Disk
   	btld.img	first Boot-Time Loadable Drivers disk
   	btld2.img	second Boot-Time Loadable Drivers disk

5. Verify that the image was written to the floppy disk correctly using the sum(C) command:
   
   sum -r /dev/fd0

   Compare the result to the checksum file on the SCO OpenServer CD-ROM (/mnt/images/boot/image_name.sum) that corresponds to the image you copied. If the checksums are the same, the floppy disk is ready for use.

   NOTE: Depending on the version of your operating system and the configuration of your hardware, you may use a device node other than /dev/fd0.

Creating floppy disks on Windows systems using ezcp

If you are using the first 3.5-inch floppy drive on your system to create an SCO OpenServer floppy disk, we recommend that you use the ezcp command, as described in this section.

The ezcp.bat file is a Windows/DOS batch file that uses floppycp to copy floppy images to drive A:. This batch file is provided on the SCO OpenServer System CD-ROM, in the \images directory.

To create an SCO OpenServer floppy disk on a Windows or DOS system using the ezcp command:

1. Format a 3.5-inch high density floppy disk using the DOS format command. Label the floppy disk appropriately.

2. Insert the SCO OpenServer System CD-ROM into the CD-ROM drive and change to the \images directory:
   
   D:
   cd \images

   If your system's CD-ROM drive uses a different drive letter, substitute the correct letter in the above example.

3. Use the ezcp command to copy the desired image to the floppy disk:
   
   ezcp boot\image_name

   where image_name is one of the following image files:

   	install.img	primary floppy Boot Disk
   	smallmem.img	small kernel Boot Disk
   	btld.img	first Boot-Time Loadable Drivers disk
   	btld2.img	second Boot-Time Loadable Drivers disk

   The floppy disk is now ready for use.

Alternative method for creating floppy disks on Windows systems

If you are unable to use the ezcp command on your Windows or DOS system to create an SCO OpenServer floppy disk because you need to use a drive other than the first 3.5-inch floppy drive, use this approach instead:

1. Format a 3.5-inch high density floppy disk using the DOS format command. Label the floppy disk appropriately.

2. Insert the SCO OpenServer System CD-ROM into the CD-ROM drive.
   

3. Use the floppycp command to copy the desired image to the floppy disk:
   
   D:\images\floppycp \f D:\images\boot\image_name

   where image_name is one of the following image files:

   	install.img	primary floppy Boot Disk
   	smallmem.img	small kernel Boot Disk
   	btld.img	first Boot-Time Loadable Drivers disk
   	btld2.img	second Boot-Time Loadable Drivers disk

   If your system's CD-ROM drive uses a different drive letter, substitute the correct letter in the above example.

   For help with the floppycp command, enter:
   
   D:\images\floppycp \h

   The floppy disk is now ready for use.
