If you requested that the Oracle VM software be preinstalled on the server when you placed your order, Oracle VM 3.2 was preinstalled at the factory. If the Oracle VM software is preinstalled on your server, but you do not want to use it, you can install any other supported operating system or virtual machine software on your server. For an updated list of operating systems supported by the server, see the latest version of the Sun Server X4-2 Product Notes at http://www.oracle.com/goto/X4-2/docs. You can also view a list of supported operating systems at http://wikis.oracle.com/display/SystemsComm/Sun+Server+X4-2+-+Operating+Systems.
Note - If Oracle VM was preinstalled, it was installed with the server set to Legacy BIOS Boot Mode. If you choose to boot the server in UEFI BIOS Boot Mode, the preinstalled image is not accessible and cannot be used. Oracle VM software does not support UEFI BIOS.
