r68977 r69054 1473 1473 1474 1474 <para>EFI provides two distinct video interfaces: GOP (Graphics Output 1475 Protocol) and UGA (Universal Graphics Adapter). Mac OS X uses GOP, while 1476 Linux tends to use UGA. VirtualBox provides a configuration option to 1477 control the framebuffer size for both interfaces.</para> 1478 1479 <para>To control GOP, use the following 1480 <computeroutput>VBoxManage</computeroutput> command: <screen>VBoxManage setextradata "VM name" VBoxInternal2/EfiGopMode N</screen> 1481 Where N can be one of 0,1,2,3,4,5 referring to the 640x480, 800x600, 1482 1024x768, 1280x1024, 1440x900, 1920x1200 screen resolution respectively.</para> 1483 1484 <para>To change the UGA resolution: <screen>VBoxManage setextradata "VM name" VBoxInternal2/UgaHorizontalResolution 1440 1485 VBoxManage setextradata "VM name" VBoxInternal2/UgaVerticalResolution 900</screen></para> 1486 1487 <para>The video mode for both GOP and UGA can only be changed when the 1488 VM is powered off and remains persistent until changed.</para> 1475 Protocol) and UGA (Universal Graphics Adapter). Modern operating systems 1476 (such as Mac OS X) generally use GOP, while some older ones still use 1477 UGA. VirtualBox provides a configuration option to control the 1478 graphics resolution for both interfaces, making the difference mostly 1479 irrelevant for users.</para> 1480 1481 <para>The default resolution is 1024x768. To select a graphics resolution 1482 for EFI, use the following <computeroutput>VBoxManage</computeroutput> 1483 command: 1484 <screen>VBoxManage setextradata "VM name"
