VM additions in dos VPC - not working

Discussion in 'Virtual PC' started by Paul from London, Feb 13, 2006.

  1. Having installed Virt pc on trial, dos 6.22 win3.11 I find the CPU is 100%
    and the application hangs, pity as it does what I want in 3.11. Anyway some
    threads suggest SP1 or VM additions (is VM additions within SP1?) so I try to
    install SP1 - it wont proceed, as the pop up box says as there is another VPC
    install cant go ahead, please remove VPC and start again. So I try and then
    it says cant install SP1 as there is no VPC on the computer. Where do I go
    from here?

    Please note I can’t find DOS drivers for my laptop CD so do I have to add
    via host OS.

    PS - I am wasting my time and is VPC not really capable of DOS?

    First, the trial of VPC includes SP1. And its not possible to update
    the trial with a full version updater.

    Its not VPC, but DOS. DOS has no CPU halt instruction, to let VPC
    know that its not using the CPU so utilization peaks to 100%. This
    will occur with a Win9x OS too, without the VM Additions.

    To get around this, run the idle.com TSR include with the DOS

    What application hangs? It may have some kind of hardware dependency
    that is not compatible with VPC.
