    CGA.BGI and EGAVGA.BGI question

    I have a DOS based program ( specific use calculator ) with 2 files in it's directory.
    CGA.BGI
    and
    EGAVGA.BGI
    I am led to believe these are it's driver files for viewing.

    The program will work OK in XP, but after the numbers and data is entered, on the Menu it has
    "View Graph" Press "A" on keyboard.

    This View Graph part of the program also has the Sum calculations from the data entered as well which is what I require to see so I can then continue my project in the Excel forum.
    I need to know how it arrived at those calculations.

    I went to my local PC "fix it" shop and he said I need an old CGA monitor because it's very old and may never work on the flat screens. I need to get an old DOS and it's older type graphics card and the monitor.

    Well, I know there were many many MANY old cathode ray TV's and Monitors thrown out just recently, so there may be "Buckly's Hope" of ever trying to sort this out.
    I think we understand what I'm trying to say here,

    Is there a way I can get this "View Graph" screen to appear ?
    Can I update those graphic files or update the program itself ?

    We have tried various settings in Properties, but nothing, it's simply no compatble-ing !
    The rest of the program views and works perfectly OK

    Thanks.

    I suspect the PC shop you took the problem to may be being a little short with the detail. Rather than needing a CGA monitor, my guess is that the CGA and EGCVGA drivers will not work with a modern motherboard equipped with an on-board gfx controller or a pci-e based card. Finding an old monitor is unlikely to fix the problem.

    So, what to do? Well, although I don't use this, I have heard good stories about DOSBox, which comes with it's own graphics rendering engine and may display the graphs that you need.
    In God we trust; all others must bring data.

    SOLVED


    It views the graph and whatever else, it worked.


    Thanks.
