Hi, everyone and welcome to the Camp Tia A plus 2 to +0-1001 module one.
Today's lesson is less than 1.6.
Bios configurations, part one
configuration of peripherals in the BIOS I'm your instructor, Bill Price.
Let's get started.
Okay, so let's start looking at today's learning objectives for this lesson. First, we're gonna look at the boot sequence, followed by enabling and disabling devices in BIOS Dayton Time, followed by clock speeds, and we're gonna round up with firmware updates. So let's go ahead and get started.
The boot sequence when a computer boots after going through post is going to try to find an operating system to boot from. We learned that from an earlier a lesson in the BIOS. There needs to be ah, boot order set that instructs the system in what sequence and where to boot from.
Normally, you would a boot from wherever your operating system is, where the operating system on the device rather is installed. The exception to this is, say friends, if you want to boot from a DVD or US beautifully or something along those lines in order to change this location, you have to change the boot order in the sequence in the BIOS
now, depending on your bios, it may be different. Here we have an example of ah Phoenix bio setup utility. The settings allow you to run the boot sequence from a floppy drive or hard drive, a CD, rum or an external device such as a USB. Like we mentioned before.
The first device in the boot order list has the boot priority, so that's where the system is going to boot from and look for first.
It would be the same in the U. E F I systems as well in the U. E F I boot sequence. They work the same as well as the older legacy or bio systems. Check the manufacturer on specific instructions on your particular more than board. As to the layout in the wear and how it's Liam set up,
make sure that your motherboard recognizes the boot device because if it doesn't, you may see in a reception like this the non system disc or disk air.
Replace and press any key when you're ready. So basically what that era means is it's not properly identifying the first boot device or the only boo device depending on your system is set up. So let's have a look at as far as the boot order and some other things. Let's go to the lab.
Okay, so let's start looking at some of the functions in the BIOS
in this feeling's bio setup utilities. Let's first look at the boot sequence. Nobu sequences you can see would be located on the tabs here across the top.
So let's talk over to the boot tab,
and you can see the priority of the devices that this system is set to start from. The first item on the list is removed devices. The next would be hard drive, followed by network boot, then CD Rahm Drive and again, according to the items specific help on the right hand side. You can make
changes to this list and organize them the way you want.
Would it?
We wanted to first look for removable devices. Then we wanted to look for the CD round drive so we would take the city Ron Drive and selected. It hit the plus time to make it second on the list, as I'm doing right now,
So now we have removal device is first
the CD ROM's drive, then followed by the hard drive in the network boot.
You would exit same changes, and that change will be made.
And again. Remember, the first item on the list is the priority device. So that's what your system's gonna boot from. First,
Um, let's move over to making changes with the date in time, the date and time on this particular example, it's found on the mains hap, and you'll see that the time is set right now for military time. Eight o'clock or 801 in the system data is 6 13 2009
Here is where you would make that change right in the biles
again. After you make that change, save exit and you're done
clock speeds. The clock speed, also called the clock rate, is the speed at which a microprocessor execute instructions. Every computer contains an internal clock that regulates the rate at which instructions are executed and synchronizes all various computer components.
The CPU requires a fixed number of clock twit ticks or
clock cycles to execute each instruction. The faster the clock, the more instructions the CPU can execute. Per second
when we look at CPU speeds or ratings, we see them rated using either megahertz or gigahertz, a processor that is 1.2 gigahertz. We could see that a speed of 3.2 gigahertz is faster, so therefore
it may be able to execute more instructions. That's what it really comes down to. A bulls down, too.
In computer terms, the higher the number of the faster the speed could execute war instructions per second. So people that need high processing processors with high intensity doing a lot of different instructions need higher CPU processors
over clocking over clocking means to run a process there faster than the clock speed for which it was been tested and approved over clocking is our popular technique for getting more performance out of your system without purchasing any additional hardware.
Because of this, because of this, over clocking is very popular. Long, hard core three D gamblers
and anyone who need faster performance out of their PCs now, depending on your motherboard over clocking, has done one of three ways by changing the jumper or dips with settings, or by changing some chips that features in your BIOS or using a combination of both.
Check your manufacturer, Ah, documentation of new particular motherboard. It was show you as far as how to over clock your motherboard. Some of the boards are geared toward over clocking, and it's laid out with specific instructions on how to do that. Now, one thing to be aware off
some of the boards will not cover the over clocking
methods, and it will make void the warranty. You again, you have to check your mother mother board to make sure that it is covered
Firmware upgrades in your bios. When we're doing firmware up race, there's gonna be a number of different ways we can do that in the older days and the older systems. Those were done from floppy disk and floppy devices, and we had toe boot off those floppy devices, and it would install the flash or the firmware upgrades.
Newer motherboards have executed Bols that they can run from right off the windows operating system.
Again, check your motherboard manufacturer in system details as far as how to upgrade your firmware, which is in your bios when we're upgrading to file bios, we want to make sure that that computer is not disturbed at all.
We want to make sure we have a reliable power source, whether it's on a ups. If it's a laptop, make sure the battery is fully charged and it is plugged in
again. Newer Biosystems do have executed Bols where they could run the upgrades right from the Windows operating system.
Flash Drive upgrades The newer you E F I bios motherboards were light upgrade bios right from a flash drive, rather pulling it from it live or rebooting the system as well. So there's many different ways that you can upgrade the firmware on your system. But again,
always check with your mother board manufacturers for details in your particular system.
OK, so let's review some of the things that we went over in this lesson. So we talked about the B boot sequence and how to make changes in the boot sequence. We jumped into the lab and looked at that. We also looked at enabling and descending devices in the BIOS on also changing the date and time, the bios as well.
We rounded out talking about clock speeds and over clocking, and we finished up talking about firmware upgrades and updates on your system
So that is going to complete today's lesson.
I hope you got ah lot out of it. I know. I sure did. And we look forward to seeing you in the next lesson. See you then.
