Symantec Technical Support or a knowledgebase document recommended that you replace your current PC DOS files with an earlier version or with MS DOS files. You want to know how to do this.


Solution



In the following Ghost versions, Ghost provides IBM's PC DOS files, version 7.0:
  • Symantec Ghost 7.0 and later
  • Norton Ghost 6.03 and later
  • Norton Ghost 2001 and later


Note: For current versions of Ghost, see the document How to create an MS-DOS system disk for Ghost.


In older Ghost versions, Ghost obtained the MS DOS 7.0 files from a location you specified or from a formatted floppy disk.

Some computers might have problems with PC DOS version 7.0. Occasionally, the PC DOS files do not work well with specific hardware or an old computer BIOS. In these situations, updating the computer's BIOS sometimes prevents the problem. Another solution is to use an earlier version of the PC DOS files or use MS DOS 7.01 instead of the PC DOS that is supplied by Ghost Boot Wizard.

To resolve these problems, replace the PC DOS files on the floppy disk with an earlier version of PC DOS files or with the MS DOS 7.01 files.


Note: MS DOS 7.0 and earlier do not work with FAT32 partitions and may have smaller limits on disk or partition sizes than later versions. MS DOS 7.01 and later, included in Win95b and later, do understand and work with FAT32 partitions. FAT32 partitions are supported by Windows 95b and later, Windows 98/ME, and Windows 2000/XP.


PC DOS files
Command.com
IBMBIO.com
IBMDOS.com
Himem.sys

MS DOS files
Command.com
IO.sys
MSDOS.sys
Himem.sys


Note: Though Ghost does not require Himem.sys, the file sometimes resolves memory problems.


Updating existing bootable floppy disks
To update a floppy disk, manually replace the PC DOS files with the MS DOS files. In some cases, even when replacing PC DOS files with earlier versions of PC DOS files, manually replacing the files might not be sufficient to resolve the problem.

In this case, you can replace the files with one of the following methods:
  • The SYS command: Remove the PC DOS files, and then use DOS's SYS command to place the new DOS files on the floppy disk. Be sure to include the file Himem.sys on the boot disk. Note that Windows Millennium Edition (Windows Me) does not allow you to use the DOS SYS command.

    If using Windows Me, create a Windows Me Startup Disk with a new floppy disk, delete all files that do not match those in the previous list of MS DOS files, and then copy the remaining files from your previous bootable floppy disk to the Startup Disk.
  • Multicast Assist: After updating Multicast Assist Wizard to use the MS DOS files or older PC DOS files, recreate the bootable floppy disk using Ghost 6.0's Multicast Assist Wizard.


Creating new bootable floppy disks
Depending on your Ghost version, you use Ghost Multicast Assist Wizard or Ghost Boot Wizard to create bootable floppy disks.
  • To configure Ghost Multicast Assist Wizard to use the MS DOS files to create bootable floppy disks, see the section "Ghost 6.0 - 6.04 Multicast Assist Wizard."
  • To use Ghost Boot Wizard to create bootable floppy disks that have the MS DOS files, see the section "Ghost Boot Wizard."


Ghost 6.0 - 6.04 Multicast Assist Wizard
The Ghost Multicast Assist Wizard saves DOS files in the Common folder and uses these files each time you create a Ghost Multicast Boot floppy disk. These are usually MS DOS files. If Multicast Assist Wizard is using PC DOS files, you can configure it to use the MS DOS files instead by replacing the PC DOS files in the Common folder.

The Common folder is located under the Template folder, which is a subfolder of where Ghost 6.0 was installed (for example, "c:\program files\Norton Ghost 6.0\template\common\").

To replace the files
  1. Delete the PC DOS files from the Common folder.
  2. Copy the MS DOS files to a temporary folder.
  3. Run Multicast Assist Wizard to create a Ghost Multicast Boot disk. When it prompts for the location of the DOS files, type in the temporary folder where you saved the MS DOS files. Multicast Assist Wizard will copy these to the Common folder.


Ghost Boot Wizard
The Ghost Boot Wizard in some Ghost versions can copy only IBM PC DOS files to the floppy, and not MS DOS files. These Ghost versions are Symantec Ghost 6.5 Enterprise Edition, Symantec Ghost 7.0, and Norton Ghost 2001 version 6.5. For these Ghost versions, use the following instructions to create a bootable floppy disk that has the MS DOS files.


Note: Ghost Boot Wizard in Norton Ghost 2002 allows you to choose MS DOS files instead of PC DOS files. If you have Norton Ghost 2002, you can use Ghost Boot Wizard to create a new bootable floppy disk that has the MS DOS files, instead of manually replacing the DOS files on the floppy disk.


To create a bootable floppy with MS DOS files
  1. Create the floppy with Ghost Boot Wizard.
  2. Remove the PC DOS files from the floppy.
  3. Use DOS's SYS command to place the new DOS files on the floppy disk. Be sure to include the file Himem.sys on the boot disk.


Updating the Ghost Boot Partition
The method for replacing the DOS files on a Ghost Boot Partition depends on your Ghost version.

In Symantec Ghost 7.5, the Ghost Boot Wizard has a option which enables you to choose PC DOS or MS DOS files when you create the Console Boot Partition Image. Use this image to install the Ghost Boot Partition. If the Ghost Boot Partition already exists and uses PC DOS files, see the section "To update an existing Ghost Boot Partition."

Symantec Ghost 7.0 and earlier do not have a feature for using MS DOS files in the Console Boot Partition Image. To create a Ghost Boot Partition that uses MS DOS files, first install a Ghost Boot Partition to the client computer, and then update the partition by manually replacing the DOS files. See the section "To update an existing Ghost Boot Partition."


Note: The Console Boot Partition Image is a file that you create in Ghost Boot Wizard. The file is an image of a DOS boot partition that includes DOS system files, Ghost files, and Network Interface Card (NIC) driver files. To enable the Ghost Console to manage a client computer, Ghost requires that the client computer have the Ghost Client installed, and that you do one of the following:
  • Use Ghost Multicast Server, GhostCast Server, or Symantec Ghost 7.5 Console to roll out the Console Boot Partition Image to the client computers. See the document Preparing a workstation for control by the Ghost Console.
  • Configure Symantec Ghost 7.5 Console to use a Ghost Virtual Boot Partition on the client computers.



To update an existing Ghost Boot Partition
  1. Create a bootable floppy disk.
    1. Create a bootable floppy disk that has MS DOS system files. A Windows 98 Startup disk is sufficient for this purpose. See the document How to create a DOS system disk for Ghost.
    2. Copy Gdisk.exe and Sys.com to the floppy disk.
  2. Use the newly created floppy disk to start the client computer.
  3. Run GDisk using the following command line:

    GDISK 1 /-HIDE /P:1 /Y /R

    The computer restarts from the bootable floppy disk.
  4. Replace the DOS files:
    1. Change to the C: drive. This drive is the Ghost Boot Partition.
    2. Delete the IBM DOS files: Command.com, IBMBIO.com, IBMDOS.com, and Himem.sys.
    3. Change to the A: drive.
    4. Type SYS C:
  5. Run GDisk with the following command line:

    GDISK 1 /HIDE /P:1 /Y
  6. Remove the bootable floppy disk and restart the computer.

To update the existing Ghost Boot Partition on many client computers at once
  1. Update the existing Ghost Boot Partition on one client computer.
  2. Create an image file of the new Ghost Boot Partition.
  3. Rollout the new image file to the client computers.


More information
Ghost does not provide a copy of the MS DOS files.

The following chart lists the method that each Ghost version uses to obtain the DOS files:
  • Method 1 - The Ghost versions listed under "MS DOS files" obtain the MS DOS 7.0x files from a location you specify or from a floppy disk formatted in Windows 95/98.
  • Method 2 - The Ghost versions listed under "IBM PC DOS files" provide the IBM PC DOS files.
  • Method 3 - The Ghost versions listed under "MS DOS and PC DOS" allow you to choose between the MS DOS files or the PC DOS files. If you choose PC DOS files, Ghost Boot Wizard provides the IBM PC DOS files. If you choose MS DOS files, Ghost Boot Wizard obtains the MS DOS 7.0x files from a location you specify or from a floppy disk formatted in Windows 95/98.
