Abstract: Responsive to a start-up of an instance of a cloud-based computing environment, metadata that is stored in a virtual trusted platform module (vTPM) is accessed. The metadata represents configuration parameters for the instance, and the configuration parameters include a security credential. The instance is configured based on the metadata. The configuration includes configuring an access control of the instance with the security credential.

Abstract: A computer system having a core logic chipset that functions as a bridge between an Accelerated Graphics Port ("AGP") bus device such as a graphics controller, and a host processor and computer system memory wherein a Graphics Address Remapping Table ("GART table") is used by the core logic chipset to remap virtual memory addresses used by the AGP graphics controller into physical memory addresses that reside in the computer system memory. The GART table enables the AGP graphics controller to work in contiguous virtual memory address space, but actually use non-contiguous blocks or pages of physical system memory to store textures, command lists and the like. Contiguous virtual memory address space must be allocated for the AGP device within the addressable memory space of the computer system, typically 4 gigabytes using 32 bit addressing.
