UEFI vs BIOS?

post #1 of 6
Thread Starter 
In layman's terms what are the advantages of this new implemented BIOS system? How is it better from the ancient IBM BIOS, in features and capabilities, and how safe is it considered to be? Does it allow access from within the OS? I'm mostly considered on security measures and remote attacks from trojans and viruses/malwares.

here are a few key differences to using the UEFI over the BIOS;

* Ability to boot from large disks (over 2TB)
* Faster boot-up (supposedly)
* CPU-independent architecture
* CPU-independent drivers
* Flexible pre-OS environment, including networking support
* Modular design

The boot time is definitely faster my media pc has uefi and between that and an ssd it's pretty much instant on.

I didnt get the cpu independent options and the modular designs. How do you mean? How did the CPU depend on the previous BIOS?

You mean a mechanical drive on uefi boots as quick as an SSD with BIOS? So would an SSD on UEFI boot that much better or will there be no improvement on booting an SSD on UEFI?

no he's saying that he is using a SSD, and with UEFI his restart time is super fast, as is mine.
feels like maybe 10 second restart lol.

Yes thats what I meant. I don't have anyway to test with a mechanical drive but the longest part of boot time is waiting for windows and that takes seconds.
