 |
|
| Hello forum again) Tell me, is it possible to download a driver for a GPU from UEFI? UEFI is capable of this? Suppose I have a laptop without an operating system, and there is a GPU driver, it is possible to load it using UEFI? |

| UEFI is a general name for the preboot environment, so the exact answer depends on which manufacturer's UEFI implementation we are discussing. However, given the number of barely functional UEFI implementations in the wild, I expect logrusx's answer applies in practice. |

EFI specification doesn't aim to specify an OS, so I don't think anybody would implement an OS at EFI level, however some time ago I stumbled on a project aiming to install linux kernel in place of EFI firmware.
I even thought of trying but didn't want to risk bricking my laptop, given the fact I don't have an optical drive which is still needed to resolve issues like broken EFI, if it's even possible.
Best Regards,

UEFI = Unified Extensible Firmware Interface. Firmware Interface. That's it, a simple firmware interface responsible for hardware initialization for the operating system to use.

GPU has its own Vbios, its own VRAM... there is also a driver for GPU operation. UEFI has very wide capabilities. I think that a small modification of UEFI or GPU driver and what you think is impossible will become real. |

You are picky on word now.
Nobody said it is impossible, it is just being said, there are no such thing exist at this time.
UEFI, is a specification, it is not one implementation, if you want to picky, the specification accept execute UEFI Shell script. you can (if you want) try to write a UEFI program to do what ever you want. |
