Device drivers & System BIOS

Basic Input/Output System (BIOS)


·         The main functionality is to perform the initial hardware checks after the computer is powered on and start up the operating system.


Device drivers & System BIOS


·         resources that can be used by an Operating System (OS) to communicate with hardware


Flashing the BIOS


·         In modern PCs, the procedure of replacing BIOS contents is sometimes referred to as:


BIOS updates


·         Repair damaged BIOS
2. Provide support for new types of attached hardware
3. Fix known programming errors discovered in the current BIOS version


EEPROM & Flash Memory


·         BIOS types that can be updated without removing the BIOS chip from a motherboard




·         Microsoft Windows OS utility can be used to view basic information about computer's BIOS


Power failure during BIOS upgrade


·         can be the cause of irreversible damage to the computer system.




·         After a normal system shutdown, when the computer is turned off, contents of the memory used to store BIOS settings are


POST Test.


·         acronym refers to a series of basic hardware diagnostic tests performed by the startup BIOS after the computer is powered on


CMOS RAM & Flash memory


·         After replacing a modular hardware component inside computer case, the updated information about specific parameters of the new device can be stored in


Boot sequence


·         After completing the initial diagnostics and assigning system resources, the startup BIOS program checks for information about secondary storage devices that might contain the OS. The list of devices and the order in which they should be checked can be found and arranged in the CMOS setup utility, and this option is commonly referred to as:


Enabled in the advanced BIOS settings menu


·         In order to work, an integrated component such as Network Interface Card (NIC) on a newly assembled computer system may need to be first:


Getting into the CMOS setup utility and enabling the virtualization technology setting


·         After launching Windows Virtual PC application technician receives error message stating that the Hardware-Assisted Virtualization (HAV) feature is not enabled on the computer. Which of the following steps might help in fixing this problem


The key set by the motherboard manufacturer for accessing CMOS setup utility during boot


·         The CMOS setup utility can be accessed by pressing:


CMOS settings can be set to factory defaults by:


·         Using a jumper that can be found on the motherboard, Reseating the CMOS battery on the motherboard, or Choosing the default configuration option in the CMOS setup utility




·         a firmware interface designed as a replacement for BIOS


user permission restrictions that can be set in BIOS


·         User password required to proceed when the computer is powered on & Password-restricted access to the BIOS setup utility (Supervisor password)


Aborted BIOS update


·         could render the computer unusable


Supervisor password


·         type of password provides the highest level of permissions in BIOS




·         Security feature used for locating stolen desktops, laptops, or tablets


Trusted Platform Module (TPM)


·         a technology that allows for storing passwords, certificates, or encryption keys in a hardware chip


Enabling the TPM security feature in CMOS setup menu


·         While trying to enable the entire drive encryption feature in Windows technician receives the following error message: "A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found". Knowing that the system has a TPM chip installed, which of the following steps might help in solving this problem


features of UEFI


·         GUI mode
2. Mouse support
3. Secure boot
4. Network access
5. DRM support


Computer's BIOS


·         A computer supporting LoJack technology has two main components installed: an Application Agent residing in the operating system which sends tracking signals to the monitoring center allowing the law enforcement to locate and recover stolen device, and Persistence Module which restores the Application Agent and allows it to survive operating system re-installation or hard drive format. The highest level of security offered by LoJack can be achieved when Persistence Module resides in:


Secure boot


·         A UEFI functionality designed to prevent the loading of malware and unauthorized OSs during system start-up is known as:


Chassis intrusion detection


·         an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature). Coupled with a hardware sensor mounted inside the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
