Reposting some old comments on UEFI, since I got riled up about it again:
UEFI is perhaps the single most egregious pile of garbage ever concieved by humans. I don't think it's possible to overstate how awful it truly is.
Here's how BIOS works: basically, the computer loads the first 512 bytes of disk into memory and jumps to it. The OS takes over from there and does whatever it needs to, like bootstrapping stage 2 and loading the kernel from the filesystem. The spec is 46 pages long and you are granted the rights to reproduce, distribute, and implement it free of charge.
Want to know how UEFI works? The spec is a 2,899 page PDF which you have to pay to use in any way, including writing an implementation.
Every copy of this specification should be found and burned. The ashes should be buried deep in a dark place and the earth above salted.
@sir my fav thing about UEFI is sometimes it can run out of storage space. And then any attempt to change settings, including bootloader ones, silently fails until you reset the NVRAM.
@sir the truth has been spoken
@sir Seems like you don't need to pay for UEFI spec to implement it, only fill out this https://uefi.org/sites/default/files/resources/UEFI_Adopters_Agreement_100907.pdf
@sir Once upon a time there was OpenFirmware that happened to suck less, but like any other good enough technology, failed miserably.
@sir also there are sub-OS-level hacks for UEFI that are impossible with BIOS.
@sir *internal screaming intensifies*
@sir I still have never managed to install Linux on a machine with UEFI without screwing something up.
Yet,i think you use uefi.
I thought that i am only guy who hated uefi until now. Thanks for info btw. I didn't know that specs had price .
@bjarnestroustrup I only use UEFI when i'm forced to, mainly I still use BIOSA
