    I have one weird problem with fullscreen cmd and with some old dos apps.
    When i put cmd to fullscreen there is red frame arround it.
    Also when i run an old dos app natively i get red frame flashing with beep sounds and a weird color palette.
    Don't you know what that means? Any help appreciated.

    video how does it look:

    It means you need to use DOSBOX/Qemu etc. XP OS & higher are not meant to run DOS games/apps that require direct access to hardware (sound/video etc). The beeping/red frame is the Hardware Abstraction Layer (HAL) introduced with NT complaining that something is trying to access the hardware directly without asking HAL nicely.

    Thanks for your reply...
    I will probably use dosbox for dos apps,
    But just curious, it worked on many xp pcs without that red frame and beeping... What could be different on this pc?
    and what about that red frame in cmd when in fullscreen?
    Thanks.

    I dunno. I just tried Commander Keen 3 in XP and I got the flashing red frame and annoying beeps in full screen. DOS allowed apps to access the hardware directly, NT and above requires drivers that work with HAL.
