What is the starting point for everything else that runs on your computer.

BIOS- Basic Input/Output System

What is BIOS an acronym for


What is the first thing the BIOS does?

It initializes the system. It makes sure you have the hardware needed to continue loading the operating system

What is a POST

Power On Self Test. This checks to see if there is any problem with hardware then prompts you for correction.

What does BIOS do after completing the POST

Looks for boot loader to load the operating system.

Where is the BIOS located

On the BIOS Chip

What are the two types of BIOS that may run?

The legacy BIOS and the UEFI BIOS

How long has the legacy BIOS been around

over 25 years.

Older operating systems accessed hardware indirectly through what?

The legacy BIOS

What is UEFI and acronym for?

Unified Extensible Firmware Interface

What is the defined standard of UEFI, that all hardware manufacturers use, based on?

Intels' Extensible Firmware Interface

What are some advantages of a UEFI BIOS

Can boot from larger storage systems, such as Guid Partition Tables (GPT) disks.

Can boot from legacy FAT formats.

Can boot from removable media.

Provides a Pre-boot Environment.

Describe UEFI's pre-boot environment

It can be used to troubleshoot before the OS is loaded.

Can transfer files.

Has it's own shell, drivers, and applications.

Can browse the internet

Can backup a storage drive

Has remote diagnostics.

Where was BIOS settings stored in legacy BIOS systems.

Complementary metal-oxide semiconductor (CMOS)

How are BIOS settings stored with the new UEFI BIOS

Flash memory

What is advantage of new Flash memory for BIOS setting storage over the legacy CMOS?

It does not require a constant power source to keep the BIOS configurations. The old CMOS require a battery to keep configurations when the computer was not powered.

In older CMOS BIOS storage system what was a way to reset the BIOS configuration?

Removea the battery..

What are basic things you can do in the BIOS after lunching the system setup?

-view and configure memory or RAM

-View and enable/disable storage devices like Hard Drive and Optical drive

--View and do some configurations on CPU

-view Date and time

What are some advanced configurable settings in BIOS

Can change how BIOS is configured

Change how the boot process starts

Can change boot settings so device order can be changed or some disabled/enabled

What are security settings that can be configured in BIOS

You can set to require pw on every bootup before OS loads

You can add supervisor pw so that no BIOS settings can be changed without pw

What extra feature do some motherboards put extra in their BIOS?

Hardware diagnostics.

What should you always do when making changes to the BIOS

Make a backup, take notes, take a picture—so that you can always go back to the former settings.

What does BIOS pw/user pw do?

System won’t start without password-OS won’t even load

What does the BIOS supervisor PW do?

Restricts access to make BIOS changes

What is windows bitlocker?

It allows Full disk encryption

What is TPM?

Trusted Platform Module

What does TPM do

Adds cryptographic functions to enable encryption of entire system through integration with the BIOS

Where is the TPM located?

It is either part of the motherboard or is added into an expansion slot

What is Lojack for laptops?

It is part of the BIOS that allows tracking down of laptop.

BIOS automatically installs a version of Lojack on any OS on the system.

Lojack sends location information—called the ‘phone home’ function.

Lojack has a theft mode which remotely locks the laptop or deletes files or forces a startup pw

What does it mean to upgrade firmware?

Could mean upgrading the nonvolatile memory or software that starts up the device.

It could mean upgrading read only memory in older BIOS by swapping out an old chip for a newer one.

Nowadays, BIOS is in flash memory so upgrading means just changing software; no need to replace any chips.

Could mean upgrading firmware in Cumputer BIOS, or in video adaptor, or game console, etc.

Why is firmware upgraded.

To provide new features or to fix bugs

Why is firmware upgrades NOT a normal maintenance process?

Firmware should only be upgraded to fix bugs are if new features are needed. Upgrading firmware runs the risk of rending system unusable.

How can you identify the current BIOS version

It flashes by quickly when starting up system.

From Windows you can see it in System information from windows utility or running msinfo32 from the command line.

What should you do before upgrading the BIOS?

Read the documentation

IF the BIOS upgrade is interrupted this could render the system unusable. So, locate a stable power source. Laptops should have fully charged battery and be plugged in. Desktops should be plugged into a UPS (Uninterruptable Power Source)

How do you run the BIOS upgrade program?

old Legacy BIOS upgrades may require a boot disk or optical media.

Most modern upgrades run as an executable from within the OS. Close all other applications before running.

How do some new motherboards make upgrading BIOS less risky?

Some have a backup BIOS chip.

Some allow upgrading from a USB flash drive.
