    Hi Bruenor and friends,

    I make a fresh install of Windows 95 but i have a problem with magic dosbox. I can only boot on safe mode if i try to boot in normal mode a get a black screen after windows logo. The img file is working fine on dosbox pc.

    These are my speqs:
    Xiaomi Pocophone F1 (snapdragon 845)
    Android 10 (maybe this is the problem?)
    Magic Dosbox v1.0.80

    And this my config file

    
    [dosbox]
    machine=svga_s3
    memsize=64
    #Amount of video memory in megabytes (0-8).
    #  The maximum resolution and color depth the svga_s3 will be able to display
    #  is determined by this value.
     #  0: 512k (800x600  at 256 colors)
    #  1: 1024x768  at 256 colors or 800x600  at 64k colors
    #  2: 1600x1200 at 256 colors or 1024x768 at 64k colors or 640x480 at 16M colors
    #  4: 1600x1200 at 64k colors or 1024x768 at 16M colors
    #  8: up to 1600x1200 at 16M colors

    Hi again:)

    If you are in safe mode then you must delete some stuff from device manager. I do it in my win95 guide on youtube.

    around 4th minute.

    I dont have any ports. It’s weird, last time it works fine but it’s been a long time. I think the problem is android 10.

    To rule out a device issue, does it work in Dosbox on your PC (Windows/Linux)?
    And just a shot in the dark, but have you enabled SVN core in your Win95 profile?

    Yes its working in dosbox windows. I tried with svn and normal core.
    Tried Roland Deschain win95 img and its boots but windows says there’s no video driver and when i try to install video driver says that cannot detect hardware.

    Svn should be turned off. Hmm is img located on sdcard or internal storage?

    Solved reinstalling windows 95. it seems the cause was a buggy s3 video driver.
    Thanks Bruenor and Alex 🙂

    Glad you could fix it. 👍 No need to thank me at least, I didn’t do anything. 😉
