video - BIOS int 10h service 0 and EGA mode -

-

i've spent lot of time trying find out happens when 1 calls bios int 10, service 0 set video mode. possible perform these actions manually using ega ports?

i've found documentation different sources, failed find sets particular mode. i'm starting thing "video mode" not register value, it's bunch of settings in ega.

to clear, i'm practicing text modes (0,1,2,3 , 7) under dosbox , qemu.

look web tauron vga utilities. code in package sets various video modes (text , graphics) using video registers , not using bios functions. of these modes appear work under dosbox, tried.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
