Abstract
An operating system for a computer system having a protection scheme with a plurality of privilege rings provides services for message broadcasting from applications at less privileged rings to virtual drivers at a most privileged ring, and from the virtual drivers to applications. The virtual drivers can perform user mode operations including message broadcasting as an application by synchronizing to a thread of a user mode message server at application time, and setting the thread's user mode context to perform the operations.
