 OS Selection
When operating system is installed and used, this option needs to be set
correctly. For example, if Windows 7 is installed or used, this option must be set
to Windows 7, otherwise blue screen would be occur when the system is
installed, or the installed system cannot be booted.
Note: Android option is only used for testing. Due to lack of corresponding
driver, the current Android system is not fully supported.
 USB Configuration
 Legacy USB Support
This option is used to support legacy USB devices (keyboard, mouse, storage
device, and etc.). When this option is set to Enabled, even under operating
systems that do not support USB, such as DOS, USB device can still be used.
When it is set to Disabled, legacy devices cannot be used in operating systems
that do not support USB.
Note: USB can still be used under EFI application, such as under Shell.
