  • efi loadthis
  • opening the source file viewer
  • and an example setup script file

  • Professional
  • Advanced

  • Desktop gets shifted horizontally on Intel BayTrail, ASUS Transformer Pad TF103

    Dear all,

    while testing my app on the Atom Z3745, the screen suddenly got rotated right by a few hundred pixels. The pixels shifted out on the right side were displayed on the left side, but one pixel line lower.

    This screen rotation problem was not related to my app, it persisted on the Android desktop after exiting my app.

    The solution was to press the on/off button twice, then the desktop was OK again.

    Since this shift could be an issue in the graphics driver, I'm reporting it here.

    The problem appeared randomly twice this evening.


    OpenGL/ES texture format GL_BGRA broken in Intel BayTrail Android Driver

    Dear all,

    I tested my app on Android 4.4 with Intel(R) HD Graphics for BayTrail , OpenGL ES-CM 1.1, and unfortunately no textures were shown at all.

    I now tracked down the problem: Even though the Intel BayTrail driver reports to support the extension GL_EXT_texture_format_BGRA8888, using glTexImage2D with format GL_BGRA seems to create a mess, so that no more textures are displayed at all. All is fine if GL_RGBA is used instead.

    Test system was an Asus Transformer Pad TF103C.

    *** FIX *** HAXM 1.1.1 on Windows 7 64bit

    For people having install issues with HAXM - specifically this issue:  "Failed to configure driver: unknown error. Failed to open driver".
    I discovered that the issue is the digital signed catalog for the 64bit driver is named wrong in the install.
    It is named in the inf file for the driver:
    but the file that is in the folder is named - this is the name for the 32bit OS driver.

    So this is what I did to fix it.

    Driver problems whilst rooting a Dell Venue 8 (3840)

    We have some Dell Venue 8's (3840 Merrifield, running 4.4.4) that we are doing a software project with that requires us to root the units, and I very carefully followed the steps provided in, and used the drivers and packages that can be downloaded from the site, exactly per instructions.


    HAXM install fails every suggested way - 577 error


    I'm experiencing an issue installing Intel HAXM 1.1.1 on Windows 7 Professional SP1 64-bit Hungarian. First: each suggested way to install HAXM fails. The normal, simply running the installer gives the message: "Failed to configure driver: unknown error. Failed to open driver".

    Installing via the hax_extract.cmd gives the 0x424 error as seen below. Driver seems to be installed, but service cannot be started:
