Lesson 2 bios/ UEFI Flashcards
where the BIOS performs a hardware check on the main components of the computer.
POST(power on self test)
If a device is malfunctioning, what occurs to notify user of a hardware issue.
Beep codes
a card that is installed on a expansion slot on the motherboard and displays a series of two or digit hex codes when troubleshooting a PC problem without video.
POST Card
A ROM chip on the motherboard that contains a small program that controls the communication between the OS and the hardware.
BIOS
Main BIOS configuration settings to configure include:
Time and Date Disable Devices Boot Order Clock Speed - Under-clocking/ Overclocking And virtualization
the bios identifies a Number of components and their settings.
Which drives are available
Which drives are bootable
How the memory is configured and when it can be used
How PCIe and PCI expansion slots are configured
How SATA and USB ports are configured
Motherboard power management features
BIOS settings are saved in the CMOS memory chip
if a pc’s time and date are incorrect their is probably a problem with what component
Lithium battery
Enables user to wake up computer remotely by sending data to it through the network
adapter.
(WOL) Wake on lan
what do you do if you forget a supervisor password
reset it by removing the lithium battery
Encrypt data on drive into code to prevent data theft
Drive encryption
job of the bios
identify, test, and initialize components of the system.It then points to the operating system
so that the OS can load up and take over
how to determine if post is working correctly
remove all of the RAM modules from the computer and power it on. The computer should emit the beep code for a computer with no RAM installed. This will not harm the computer.
*If you boot a PC and see a black screen with a white
blinking underscore on the top left, the issue could be
the?
boot order
BIOS setup utility
Main - Basic system configuration
Advanced - Advanced system settings
Boot - Boot device options and boot order
Security - Security settings
Power - Advanced power management configurations
JUSTw00t! - Advanced voltage and clock settings
Exit - BIOS exit options and loading default settings
configures the same settings as traditional BIOS but also provides additional options. For example, provides a mouse-enabled software interface instead of the traditional BIOS screens.
UEFI -unified extensible firmware interface
when installing a dedicated, graphics, network or video card you should do what to the motherboards native built in features ?
disable them
allow for different levels of access to the BIOS settings,
BIOS passwords
allows your pc/laptop to be located locked or have all the files deleted
LOJACK
switch that triggers when a computer case is opened. Set BIOS to record when the switch is triggered so the owner can tell is the case has been tampered with
Intrusion detection
this is a chip designed to secure hardware by storing encryption keys, digital certificates, passwords, and data.
TPM trusted platform module
a UEFI security standard that ensures that a computer only boots an OS that is trusted by the motherboard manufacturer. Secure boot prevents an “unauthorized” OS from loading during startup.
secure boot
Bios monitoring
temperature fan speeds voltages clock/bus speeds built in diagnostics
UEFI EZ mode
Change the time and date.
Select the language of the program.
Use the EZ Tuning Wizard to automate the creation of RAID storage and to assist with system overclocking.
Use EZ System Tuning to set the system performance mode.
Enable or disable SATA RAID.
Select the boot device priority.
UEFI Advanced mode
Main – Used to display computer information and change the basic configuration. It allows you to set the date, time, language, and security settings.
Ai Tweaker – Used for changing the CPU overclocking settings and memory operating settings. Always be cautious when changing these settings. Incorrect settings could cause the system to malfunction.
Advanced - Used to change the settings for the CPU and other devices. Always be cautious when changing these settings. Incorrect settings could cause the system to malfunction.
Monitor - Used for displaying temperatures, power status, and changing fan speed settings.
Boot -Used for changing the boot options.
Tool - Used for configuring options for special functions
.
Exit - (Figure 10) Used for selecting the exit options a
key to return to UEFI EZ mode
