Extensible Firmware Interface Specification
Most images are loaded by the boot manager. When an EFI application or driver is installed, the
installation procedure registers itself with the boot manager for loading. However, in some cases
an application or driver may want to programmatically load and start another EFI image. This can
be done with the
LoadImage()
applications during the driver's initialization entry point. Table 3-9 lists the functions that make up
Image Services.
