DOS 6.2.2 & VM Additions

    (I searched the FAQs and prior posts but did not find this addressed.)

    I installed DOS 6.2.2 under VPC 2004 SP1 running on Win2kPro-SP4. Other than
    a few hicups with the floppy drive everything seems in place. I have loaded
    and run a number of programs from floppies. So far, so good.

    When I select the "Install or Update Virtual Machine Additions" it just sits
    there. If I click on the "CD" tab at the top it displays the message about
    releasing the image. If I try to go to drive "D:" it says invalid drive. It
    will allow me to release the image and then to load the image from the host
    file but then I cannot access this one either.

    I deleted the first DOS VM and then installed again. Same thing. I
    uninstalled VPC and downloaded another copy which when installed demonstrated
    the same properties. So for the moment I have a very nice floppy-centric DOS
    2.1 type of system without printer, network, shared files, or CD.

    Can anyone help or am I going insane?

    Thanks.

    The DOS additions must be installed manually. You use the DOS
    Additions VFD and mount it to the floppy drive. There is no cd-rom
    drivers, autorun options for DOS OSes, so the Additions menu install
    won't work.
    C:\Program Files\Microsoft Virtual PC\Virtual Machine Additions\DOS
    Virtual Machine Additions.vfd

    You missed on critical option for VPC Info (a lot of people miss it.),
    the VPC help. Here's the info for DOS Additions, see the help file
    for better formatting:

    Installing Virtual Machine Additions for MS-DOS
    You can perform a standard installation or a manual installation of
    Virtual Machine Additions for MS-DOS. By using the following details
    about a manual installation, you also can write a batch file that you
    can use to perform an unattended installation. For instructions about
    how to perform a standard installation, see To install Virtual Machine
    Additions for MS-DOS.

    Locate the Virtual Machine Additions for MS-DOSĀ® virtual floppy disk
    (DOS Virtual Machine Additions.vfd) on the installation CD. To install
    Virtual Machine Additions for MS-DOS, do the following:

    Start a virtual machine that is running a Windows operating system.
    In the virtual machine window, log on to the guest operating system as
    Administrator or a member of the Administrators group.
    On the Action menu of the virtual machine, click Install or Update
    Virtual Machine Additions. If you are unable to move the mouse pointer
    to the Action menu, press the host key to release the mouse pointer
    from the virtual machine window.
    When prompted for confirmation, read the information, and then click
    Continue.
    When the Virtual Machine Additions InstallShield Wizard opens, click
    Cancel, and then click Yes.
    Double-click My Computer, right-click the CD drive icon, and then
    click Open.
    Copy the contents of the DOS folder to a floppy disk.
    Start the virtual machine that has MS-DOS installed on it, and then
    copy the contents of the floppy disk to the virtual machine.
    After the contents of the floppy disk are on the virtual machine, do
    the following to install Virtual Machine Additions for MS-DOS:

    Mouse.com
    This is the MS-DOS mouse driver for use with Virtual PC. It can be
    loaded at any time by running Mouse.com. This file should be copied to
    a known location on the virtual hard disk and a startup line should be
    added to to the Autoexec.bat file, for example, C:\VmAdd\Mouse.com
    Idle.com
    This file is a utility that will stop MS-DOS from using 100% of the
    CPU cycles when it is idle. It can be loaded at any time by running
    Idle.com. This file should be copied to a known location on the
    virtual hard disk and a startup line should be added to to the
    Autoexec.bat file, for example, C:\VmAdd\Idle.com.
    Note

    This utility will not prevent MS-DOS from using 100% of the CPU if you
    start a program.
    Cdrom.sys
    This file is the MS-DOS CD-ROM driver. It should be copied to a known
    location on the virtual had disk. To access the CD-ROM under MS-DOS
    you will need to load this driver in the Config.sys file; for example,
    device=C:\VmAdd\Cdrom.sys /D:idecd001 /L:E where /D: is the name of
    the CD device and /L: is the drive letter to use. You will also need
    to load Mscdex.exe in the Autoexec.bat file; for example,
    C:\DOS\Mscdex.exe /D:idecd001 /L:E /M:8 where /D: is the name of the
    CD device, /L: is the drive letter to use, and /M: is the number of
    buffers to use. For more information about Config.sys and
    Autoexec.bat, see the documentation included with DOS.
    Fshare.exe
    This file is the MS-DOS shared folder driver for use with Virtual PC.
    It can be loaded at any time by running Fshare.exe. This file should
    be copied to a known location on the virtual hard disk and a startup
    line should be added to the Autoexec.bat file, for example,
    C:\VmAdd\Fshare.exe.
    Important

    To work correctly, the lastdrive variable must be defined in the
    Config.sys file, for example, lastdrive=z.

    Thanks for the more detailed info. I thought I was going crazy (not that that
    is a new thing for me.) The speed and detail of your help was amazing. Thanks.

    I read the detail that you wrote but it sounds like somewhere along the line
    I need to get my hands on the compressed DOS 6.22 installation disks. I can't
    find mine. Where do I get it? Many thanks.

    Allow me to hijack this and jump in here:

    If I attach a real CD-Rom to a real booted DOS (if the DOS has MSCDEX.EXE)
    then I can read the CD-Rom!

    I just can't read the CD-Rom image that's created by the Virtual Machine
    Additions... I can see a DOS folder using DIR, buit I can't run or copy the
    files that I see there. The folder does me no good.
    There's no Installation CD if you download Virtual PC from Microsoft's Web
    site. That's confusing (although you pointed out the right folder above).

    Then its here

    C:\Program Files\Microsoft Virtual PC\Virtual Machine Additions\DOS
    Virtual Machine Additions.vfd

    in a default installation.

    Hi, my problem, my machine does not have a floppy disk. I could use a cdburnerxp to burn the five files on a cd, which I get from unpacking the vmadditions.iso with winrar or isobuster.
    It is not possible to open the iso file with the floppy menu item of virtual pc, I tried.
    Is there a program which permits me to creat a floppy img file from the vmadditions.iso files?
