Excellent Lecture

thanks a lot!

besttt video

just beautiful explanation

Also, a small BIOS is necessary because you'd want the OS to be opinionated and have its own bootloader. And a small MBR (or now, EFI System Partition) is required because it should only really store the stage 1 bootloader. A partition table such as MBR Partition Table or GUID Partition Table is required for a storage device because every OS will also want to have its own filesystem format, and you may want to have multiple filesystems, but the BIOS/UEFI should not have to know all of them. The reason the MBR Partition Table can only recognize 4 partitions as primary is because it was designed to not use too much of the disk space, at a time when disk space was a premium. So everything is sensible 🙂.

There's no option for me to write there. No matter what I press.

I just started but very encouraging.

what is the textbook you keep referecing it but nowhere does it show

Hey dr.kleiner what does a computer do when you press the start button

this was some good video on booting!

Pretty close.

thanks

Amazing Explanation

It was difficult to focus on the information due to the forced accent. Please try to speak normally

Excellent explanation and thoroughly explained the concept. Can we have complete playlist of this course?

Discuss OS for Supercomputers & Distributed OS -- Er. Sunil Pedgaonkar, India, Consulting Engineer (IT), India

May I ask what is the textbook mentioned on the first slide?

Very useful and well explained, thank you

thank youu

Can you provide me the boot loader images that you used in the video?

Hello my friend, have a good time I am using Apache Netbeans IDE 16 in the SSH Connection window The Known Hosts section is disabled for me, I wanted to see how to activate this section? Please advise. thank you

bravo

Good job sir!

Sir can you please share the slides so that we can study from it.

Ok, and who came up with this? Why is it done in this specific way and not in other?

great explanation 👏

thank you Sir

Good presentation. It's really helpful.

Actually, I have studied that The CPU doesn't get instructions from BIOS, in fact when the device resets, all its registers are set to zero except Code Segment(CS) which is set to (0xF000), and Instruction Pointer (IP) set to (0xFFF0), e.g. the first instruction that the CPU has to fetch and execute is already hard coded into the CPU registers by the manufacturers and it points at physical address CS+ IP (0xFFFF0). So the first instruction is fetched from location 0xFFFF0 is a jump instruction that instructs the CPU to jump to the ROM BIOS location.

thamks!

Really like it!

Absolutely perfect explaination. I have been looking for simple details, like about what does MBR have and it's connection to /boot/grub/grub.conf. This video is wow. Thank you thank you.

No host displayed in terminal ???

Awesome video but I have a question: How can the hypervisor intercept the unsafe instructions? (I don’t know much abouthardware) And also: From my understanding, the trap gets created because the guest OS runs above ring 0 right? But what does that actually mean?

Thank you add more content

Great Content, thank you .

Can we get slides of all these lectures?

GREAT

great explanation, thanks!

Very lovely presentation. Is there any chance we can get the slides?

Thanks for the content

I am cleared now!

@ Dhananjai Rao, in the video at 8:22 you mention boot loader loads OS into memory...do you mean memory as in RAM?

Are the boot loader and bootstrap loader the same.... because I got a question in my test which had both the options.... Please help someone

I owe you cup of coffee thanks

Thank you for this:)

the only video that could explain the whole process properly,...thank you so much!!
