37 Démarrez l’ordinateur pour la 1ière fois
Le BIOS est un ensemble d’instructions qui se trouvent dans un puce de mémoire nonvolatile. Lorsque l’ordinateur démarre, le basic input/output system (BIOS) exécute un auto-diagnostique (POST) pour vérifiez les composants internes. Une touche ou une combinaison de touches du clavier permette accès au programme de paramètres du BIOS. Le programme de paramètrage du BIOS permet de régler les paramètres des composants de l’ordinateur. Slide 37 – Boot Computer for the First Time 3.9 Boot the computer for the first time When the computer is booted, the basic input/output system (BIOS) will perform a check on all of the internal components. This check is called a power-on self test (POST). The BIOS is a set of instructions stored in a nonvolatile memory chip. Nonvolatile means that the memory retains its contents even if the power is disconnected. A special key or combination of keys on the keyboard is used to enter the BIOS setup program. Most computers use the DEL key. Your computer may use another key or combination of keys. The BIOS setup program displays information about all of the components in the computer. The BIOS setup program is used to configure any settings that the computer components may have. The BIOS setup will allow you to modify settings that control how the computer will boot. After completing this section, students will meet these objectives: Identify beep codes Describe how to enter BIOS and use settings

38 Identifier les codes Beeps
Le POST vérifie si tous les composants matériaux de l’ordinateur sont fonctionnels. Si un composant ne fonctionne pas correctement, une erreur est communiqué sous forme de beeps. Un seul Beep, informe que l’ordinateur est fonctionnel. Si le POST trouve une erreur matériel, l’ordinateur va émettre une série de Beeps. Chaque manufacturier de BIOS a un code unique pour chaque erreur (beep court, beep long, nombres de beeps). Consulter la documentation de la carte-mère pour comprendre les Beeps du POST. Slide 38 – Identify Beep Codes Identify beep codes POST checks to see that all of the hardware in the computer is operating correctly. If a device is malfunctioning, an error or a beep code alerts the technician that there is a problem. Typically, a single beep denotes that the computer is functioning properly. If there is a hardware problem, the computer may emit a series of beeps. Each BIOS manufacturer uses different codes to indicate hardware problems. Consult the motherboard documentation to view beep codes for your computer.

39 Paramétrage du BIOS Le BIOS inclut un logiciel qui permet de paramétrer le BIOS selon la configuration du matériel. La configuration est enregistrée sur une puce semi- conducteur à oxyde de métal complémentaire (CMOS). Le CMOS conserve sa mémoire par la pile de l’ordinateur. Si cette pile est déchargée, la configuration sera perdue. Remplacer la pile et reconfigurer le CMOS. Slide 39 – BIOS Setup Describe BIOS setup The BIOS contains a setup program used to configure settings for hardware devices. The configuration data is saved to a special memory chip called a complementary metal-oxide semiconductor (CMOS). CMOS is maintained by the battery in the computer. If this battery dies, all BIOS setup configuration data will be lost. Replace the battery and reconfigure the BIOS settings.

40 Logiciel qui paramètre le BIOS
Les paramètres du BIOS sont établis: Slide 40 – BIOS Setup Program Describe BIOS setup BIOS settings are configured in the BIOS setup program. To enter this program, you must press the proper key or key sequence during POST. Most computers use the DEL key. Your computer may use another key or combination of keys. Here are some common BIOS setup menu options: Main - System time, date, HDD type, etc. Advanced - Infrared port settings, parallel port settings, etc. Security - Password settings to setup utility Others - Low battery alarm, system beep, etc. Boot - Sets the boot order of the computer Exit - Exits the setup utility Student Activity: The student course content includes a lab, Boot the Computer. To complete this lab, students will boot the computer for the first time, explore the BIOS setup program, and change the boot order sequence.

Installation des composants Connexion des câbles Description du BIOS Description du POST Slide 41 – Chapter 3 Summary Some of the important concepts to remember from this module:  Cases come in a variety of sizes and configurations. Many of the components of the computer must match the form factor of the case. The power supply changes AC voltage into DC voltage for the computer components to use. The CPU is installed on the motherboard with a heat sink/fan assembly. RAM is installed in RAM slots found on the motherboard. Adapter cards are installed in PCI and PCIe expansion slots found on the motherboard. Hard disk drives are installed in 3.5 inch drive bays located inside the case. Optical drives are installed in 5.25 inch drive bays that can be accessed from outside the case. Floppy drives are installed in 3.5 inch drive bays that can be accessed from outside the case. Power supply cables are connected to all drives and the motherboard. Internal data cables transfer data to all drives. External cables connect peripheral devices to the computer. Beep codes signify when hardware malfunctions. The BIOS setup program is used to display information about the computer components and allow the user to change system settings.
