The scope of UEFI is somewhat greater than that of traditional BIOSes. |
16 |
Both do various hardware initialization and such, but UEFIs (can) have |
17 |
a number of additional features, including more flexibility in what it |
18 |
can launch from where (eg. network booting without iPXE) and even an |
19 |
interactive shell. See [1] for a less organized list of features. |

I'm unfamiliar with this project in specific, but I'm going by the line |
22 |
|
23 |
This is EFI-based bootloader for BIOS-based computers created as a |
24 |
replacement to EDK2/Duet bootloader http://www.tianocore.org. |
25 |
|
26 |
I have a box running Duet, which is an UEFI implementation that can be |
27 |
launched by (eg.) the extlinux boot loader on a legacy BIOS system. |
28 |
Once Duet is launched, the system is mostly indistinguishable from a |
29 |
native UEFI system that has booted into it's UEFI firmware. |
30 |
|
31 |
From here, Duet can let the user go through menus to select an EFI |
32 |
executable to launch (a EFI-stub enabled kernel or some sort of boot |
33 |
loader), or it can automatically launch something based on existing |
34 |
configuration. |
