Definitions

  • the Egenera BladeFrameTM processing platform allows an administrator to configure (under software control) at least one virtualized processing area network (PAN) system having one or more inter-communicating processors, each without a local disk or other boot device of any type.
  • PAN virtualized processing area network
  • Figure 4 illustrates a particular embodiment of the invention adapted for a platform analogous to that of figure 2.
  • the emulation logic for the BIOs run time service is similar to the logic used in device drivers that provide emulation, such as those used in the art. However, those techniques have not been used in the context of BIOs run time services.
  • emulation logic for BIOS disk services involves first translating LNT 13 functions to SCSI packets, then transmitting the SCSI packets over the medium for service by a control node such as that described in the incorporated patent application.
  • OS device drivers typically do not service LNT 13 calls, but handle SCSI packet requests directly.
  • the LNT 13 to SCSI translation mechanism, where the SCSI device is a local disk, is known in the art.

Abstract

L'invention porte sur: un système et un procédé de virtualisation du BIOS et de ses services de temps d'exécution; sur un système de traitement comportant: un processeur, une mémoire à adresse physique spatiale prédéfinie, un support d'enregistrement, et un milieu de communication entre le processeur et le support d'enregistrement, le système de traitement pouvant fonctionner dans un environnement de pré-exécution dans lequel une partie donnée de l'espace de l'adresse physique contenant une RAM sert à mettre en correspondance les routines des services de temps d'exécution; et sur un système de virtualisation du BIOS comprenant une image des instructions BIOS exécutables par processeur se trouvant sur le support d'enregistrement, et des instructions exécutables par processeur qui récupèrent les images BIOS dans le support d'enregistrement et les stockent dans la RAM correspondant à la deuxième partie donnée de l'espace de l'adresse physique.
