Boot devices and media

Boot devices and media

SCO OpenServer requires either of the following boot devices:

The SCO OpenServer media kit provides both a primary installation floppy disk and the installation CD-ROM. In addition, images of all floppy disks you might need exist in the /images/boot directory on the CD-ROM. These include:

install.img
An image of the primary installation disk, which you can use to replace a lost or damaged copy.

notebook.img
An image of a small kernel installation disk, for use on systems with small memory (16 or 24MB) configurations. This kernel has all of the disk drivers removed except for IDE/ATAPI (wd) and Adaptec 1520 (smad). Kernel buffer allocations are also reduced and may affect installation speed.

btld.img
An image of the Boot-Time Loadable Drivers disk, containing drivers for SCSI host adapters not supported by the primary installation diskette. There are also additional BTLDs provided for convenience.

You can create floppy disks containing these images with the ezcp command provided on the CD-ROM, or you can use commands specific to the SCO OpenServer system or the DOS/Windows system. 

Creating installation media using ezcp

The ezcp command is available for use with UNIX or Windows/DOS and is located in the /images directory on the SCO OpenServer installation CD-ROM. ezcp.bat is an MS-DOS batch file that uses floppycp to copy floppy images to drive A: (the first 3.5-inch floppy drive). ezcp is a UNIX shell script that copies images to /dev/rfd0135ds18 (also known as drive A:). The file /images/README contains a description and instructions.

Perform the following steps to have ezcp copy images to the first 3.5-inch floppy drive; if you need to specify another drive, use the dd or floppycp command.

  1. Insert a formatted disk into the floppy drive.

  2. Move to the images directory on the CD-ROM. (For UNIX users, this is usually mounted on /mnt. DOS/Windows users should use the appropriate drive letter.)

  3. To run ezcp from the images directory, enter:

    ezcp image

    image is the name of the image file. For example, under a UNIX system, to copy the image from install.img, enter:

    ./ezcp boot/install.img

    Under MS-DOS or Windows, enter:

    ezcp boot\install.img

    Note that the image file might be in a different directory from the ezcp script, as in the above example.

  4. Be sure to label the finished diskette appropriately.


Creating installation media - UNIX

You may be able to use the ezcp command to create installation media.

If ezcp does not suit your needs, to create a floppy disk from the images found on the SCO OpenServer installation CD-ROM in /images/boot:

  1. Format a 3.5-inch high-density diskette using the format(C) command.

  2. Label the diskette.

  3. Change to the directory containing the disk images:

    cd /mnt/images/boot

    NOTE: The example above assumes that your CD-ROM is mounted on the /mnt directory. If it is mounted on a different mount point, substitute that for /mnt in the example above.

  4. Use dd(C) to copy the image to the diskette:

    dd if=image.img of=/dev/fd0 bs=18k

    image is the name of the image you want to copy.

  5. Verify that the image was correctly written using sum(C):

    sum -r /dev/fd0

    Compare the result to the checksum file in /mnt/images/boot that corresponds to the image you copied.

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



Creating installation media - DOS

You may be able to use the ezcp command to create installation media.

If ezcp does not suit your needs, SCO OpenServer includes the floppycp command, which enables you to create installation images from a DOS or Windows system. To do so:

  1. Format a 3.5-inch high-density diskette using the DOS format command.

  2. Label the diskette.

  3. Insert the SCO OpenServer installation CD-ROM into your CD-ROM drive. This procedure assumes that your CD-ROM is drive D:; if this is not the case, substitute the appropriate drive letter.

  4. Use the floppycp command to copy the image to the diskette:

    D:\images\floppycp \f D:\images\boot\image.img

    image is the name of the image you want to copy.

    For help with the floppycp program, enter:

    D:\images\floppycp \h
