I like how these videos are at a steady pace and explained thoroughly. Better than some college courses.

FINALLY. Someone who actually explained the difference between these three. Thank you so much.

Well, after decades of working with computers i finally now understand difference between BIOS and CMOS as well recognise what is the UEFI vs thinking it too is the BIOS. Your video's man does wonders for learning and relearning what we thought we learned. Since i just bought a new Motherboard for my first personal build, i decided to brush up on my PC Motherboard knowledge. I just came straight to PowerCert for clear concise well explained videos.

Hi
I just today found your tutorial, and I give you a big thumbs up, I have never found a tutorial like yours. It explains so, so well, and the animation makes it very easy to understand.

A wonderful refresher of terminology and definitions before my job interview. Thank you for uploading. Great job on narration, animation and subject value.

Good morning. I can’t believe I’m years late replying to this. Do you have any idea how great this video is? Wow. Extremely informative. I’m scoring 850-852 in a test from 650-960. And the BIOS does come up a lot. This video has make me see more clearly now. I can’t wait to watch your other videos. Thank you kindly for making this video. 🙏🏻

Channels like these are becoming quite rare... Keep up the good work! Worthy of more likes and subscriptions...!

The most important difference between (legacy) BIOS and UEFI is the way of organising the boot process. For UEFI there was an EFI boot partition introduced where boot loader data for various operating systems are stored. This way it is easier to build and maintain multihomed PCs (with multiple OS installed).

Please don't stop uploading videos 👍❤

Completely forgotten stuff thank you for my memory refreshing. If you are not working on a daily basis with computers you are not worried about this part of computing - right ?? Once in a while is a good idea to refresh your basic knowledge about your computing machine. Thank you very much for a short AND simple technical language class :o)) TWO THUMBS UP !!

These are the information videos i really enjoy. Short and to the point, no filler to confuse the listener. Many channels have people who love talking, and putting in nonsensical B.S. that get them off track.

[coooooooolguy]

OK! I enjoyed all of the brief details that was mentioned about BIOS and UEFI differences as we are all here to help each others to know more about computers and glad that a channel have some info like this. Keep going and way to go.

ahhh thanks....try to read several articles and still confuse between bios and cmos seeing your video clear the doubts....your video is the best....thank you very much.

What you call the "CMOS chip" is the real-time clock. A clock needs to run constantly, which is why it has its own power supply (the battery). The manufacturer of the original clock chip included 44 bytes of storage. This was powered by the same battery. This is where your "settings" are stored. "Clearing CMOS" means clearing these bytes of RAM.

For someone new uefi surely looks less scary, but for us who have used bios for a long time having a mouse or colors is not very important

EXCELLENT tutorial ! So well explained ... straight to the point, no silly "jokes". Very impressive. I don't believe in subscribing to anyone's channel, but yours is so good that I had to ... you are my 2nd subscription :)
