    Hi I'm new and need advice. I have a new Toshiba A200 with ATI Mobility Radeon™ HD 2600 graphics, and my problem is I have older applications that require 256 colors to work. I can see my graphics setup does not offer anything but true or high color, and so far I have not found how to disable it. Not that I'd know if disabling it would still allow any video to display.

    I was hoping I could setup a profile that I'd use when I need 256 colors, then switch back.

    Any help would be greatly appreciated as one of the programs needing 256 colors navigates this boat!

    Right click on the application icon, go to Properties, click on the Compatibility tab, and check the run in 256 colour box.

    Tried that first off. I've run this program on several machines with windows from 95 thru to xp and that always does the trick. But on this new laptop with the ATI graphics, which also has Win xp, it does not.

    Looking at display properties - settings - advanced - adapter - list all modes
    I see only true color and high color available.

    It doesn't run even when you select run in Win95 mode in addition to 256 colours in Compatibility Settings?
    And you will not be able to make XP run in 256 colour mode unless you uninstall your video drivers or hack them somehow.

    Well Budding, It does not run when Win95 mode and 256 colours are set.
    Big problem. Need this machine to run navigational program at times. So, all suggestions considered. Will uninstalling the video drivers affect or unable screen display? Not tried this before.
    Thanks for your help

    I had same problem on Toshiba A200 with dual boot Vista & XP.
    Trying to run C-Map 256 colour with XP
    I uninstalled the ATI graphics driver I had in XP.
    XP then used its default Display driver.
    Now C-Map works fine in 256 colour compatability mode.
    I had to adjust the screen resolution (right click on screen then select properties)
