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).

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.

Respectfully, Jim Maloney wrote "Safe Boot" where I think he intended to refer to Secure Boot. "Safe Boot" is not actually the same term; it has historically referred to an option for starting Windows with many feature and options disabled, for the purpose of troubleshooting or getting Windows running after a driver update or setting change caused it not to run (so that you could back out the offending change).

In short, the BIOS or UEFI BIOS is a medium between your operating system and hardware, This is done for 2 reasons security and simplicity. 1) The BIOS/UEFI will prevent psychical damage to your hardware (set limits to what the operating system can and not can do such as voltages cpu, memory, sensors to detect failure and shut off the pc before more harm is done) 2) The operating system has to obey rules set by your BIOS and doesnt need special drivers to control important aspects of your CPU and Motherboard because those are inside the BIOS this makes it secure and easy for OS'es to run on that hardware

How to configure bios to work with UEFI hard drive
@JdMetal4 жыл бұрын
I disagree about your point no 1....modern OS bypass BIOS/UEFI at certain extends settings once it was installed.....BIOS is like the initial firmware or we can called it Operating System at the very basic..hence the name Basic Input Output System....this is where you tell your mobo to enable/disable or any misc settings before we installed OS, e.g storage configurations AHCI,Legacy,Raid. Once your OS and drives up and running, your OS basically already has the control over your hardware, at certain extends. You can from OS level set CPU voltages/frequency/RAM , but stability might not be the best ! Off course at the very low level , OS can't change boot sequence, type of SATA (AHCI or RAID or Legacy) to name a few and some advanced settings that might only viable only at very low level. *Disclaimer, this my experience dealing with Windows since 1997. I'm not sure how Linux or other OS handles their OS at kernel level.

@james_hake6 жыл бұрын
MBR is short for Master Boot Record and is sometimes called the Master Partition Table. While GPT is short for GUID or Globally Unique Identifiers Partition Table When you first initialize a storage device such as a hard drive or SSD, you need to give it a partition style which is either an MBR or GPT type. The MBR is just a "record" stored on the first sector of a disk that tells the BIOS/UEFI what partitions are on the disk (hence why it is also called a Master Partition Table) and which partition contains the operating system. When the BIOS is done running POST, it goes to the first disk specified in its boot sequence and when it does, it looks at the MBR to see which partition contains the OS so it run it. A disk with a MBR partition type is limited to only having 4 primary partitions on the disk that an OS can be stored on and can only recognize drives under 2.2 terabytes. The MBR is an older technology and is still used today but is the main and only partition scheme if you are using a traditional BIOS. If the MBR is overwritten or damaged, you most likely will have to fix it or you may end up screwed if you can't. On the other hand, GPT is a feature of UEFI motherboards and addresses the limitations of MBR. First, GPT have globally unique identifiers for each partition which in theory lets you have way more partitions on a disk opposed to an MBR disk; however, Windows will only let you create up to 128 partitions with GPT. Second, GPT allows you to use disks over 2.2 TBs and also stores the Partition Record in multiple places on the disk in case something goes wrong so it can rebuild the Boot Record/Table. So in Summary, MBR is an older partition style used with BIOS motherboards that has information about the partitions on a disk and which partition contains the operating system so that the BIOS can find it and boot into it. With MBR you can only have 4 primary partitions and disks under 2.2TB. GPT is a newer partition style used with UEFI motherboards that does everything MBR does except it can have up to 128 partitions (Windows), supports disks over 2.2TBs, and stores partition info in multiple sections of the drive for increased data redundancy.

Did you watch the whole thing? He said way more than "it has a nice interface."

@@shade0636 for a very common user it says a lot, but maybe you can enlight me. Where are the so called Secure Boot keys stored since neither BIOS nor UEFI can understand a filesystem? Does UEFI interprets the MBR the same way BIOS does? Is the same sector loaded for both UEFI and BIOS? Why it supports larger drives? Does it introduce a new partition table format beyond GPT? Can the same disk be booted either on BIOS or UEFI systems? Tell me where these answers are on the video. At the end, he said "way more" things

@@shade0636 yes, the video explains BIOS in detail, and then, at 4:17 explains UEFI in about a minute. That´s way more (nice interface, supports larger drives, can use the mouse and secure boot), so the video "lacks many things about UEFI"

And is something no one realy needs. Most of Unixes give a sh** on standard disks geometries. They all have their own ones and have no problems with large disks and the (artifical) boot size limitations.

By the way, UEFI can still look like the old blue screen (we call it text mode) by turning off the graphic module.

That's not going to help..... The CMOS battery is used to keep the contents of the BIOS saved in a chip. The BIOS has nothing to do with the settings on your operating system. It can maybe remove the CMOS/BIOS password, but it cannot help with the Windows password.

Do motherboard manufacturers include pc speakers anymore, my motherboard from 2012 didn't include one. I do really miss the blue basic bios though.

i know its an old comment but i don't think so I haven't seen almost any motherboard with speakers. I have seen, some, but they were mostly old ones. my a320m mobo (not new, but not old either) didn't have one. it has i think 4 small leds that indicate the post status

Vouw - could you try and tell a little more about UEFI? I was very happy with the video, until you got to UEFI. You really think the major difference between BIOS and UEFI (UEFI is by the way NOT a new BIOS - it's a totally new kind of firmware ditching BIOS where it has belonged since the beginning of the 90's) is the fact that you have a graphical user interface when you change settings? How about the completely different boot process from the old BIOS - the UEFI disk partition - the fact that UEFI is OS aware as opposed to BIOS - etc.
