Title (EN) DISPLAYING A BIOS UPDATE PROGRESS
(FR) AFFICHAGE D'UNE PROGRESSION DE MISE À JOUR DE BIOS
Abstract:
(EN) The update progress of a basic input/output system (BIOS) is displayed on a display screen. A first chipset lock is applied to a first region of a shared serial peripheral interface (SPI) chip of the BIOS of a computer system containing a first program of instructions. A system management memory mode lock is applied to a second and a third region of the shared SPI chip containing a second and third programs of instructions respectively. The second program of instructions is updated, and control of the BIOS is transferred to the updated second program of instructions. The updated second program of instructions updates the first program of instructions. The BIOS update progress visual is displayed on the display screen of the computer system while updating the first program of instructions.
(FR) Selon l'invention, la progression de mise à jour d'un système d'entrée/sortie de base (BIOS) est affichée sur un écran d'affichage. Un premier verrouillage de jeu de puces est appliqué à une première région d'une puce d'interface périphérique en série partagée (SPI) du BIOS d'un système informatique contenant un premier programme d'instructions. Un verrou de mode de mémoire de gestion de système est appliqué à une seconde et à une troisième région de la puce SPI partagée contenant un seconde et un troisième programme d'instructions respectivement. Le second programme d'instructions est mis à jour, et la commande du BIOS est transférée au second programme d'instructions mis à jour. Le second programme d'instructions mis à jour met à jour le premier programme d'instructions. Le support visuel de progression de mise à jour de BIOS est affiché sur l'écran d'affichage du système informatique tout en mettant à jour le premier programme d'instructions.
