BIOS classes

  • Article

The virtual BIOS is a software image that is loaded into RAM to configure some of the basic aspects of and boot a computer system. There is one BIOS element per computer system and that element cannot be replaced or removed. Thus, there is no resource pool for adding new BIOS elements to the virtual machine. The BIOS element also does not have its own SettingData class to describe the settings for the BIOS. Settings for the BIOS, such as serial numbers, boot order, and num lock state, are found in the Msvm_VirtualSystemSettingData class.

The following are virtualization WMI classes related to the BIOS. These classes are in the \\.\Root\Virtualization namespace.
