### What is Limine?
|
||||
|
||||
Limine is an advanced x86/x86_64 BIOS/UEFI Bootloader which supports *modern* PC features
|
||||
such as Long Mode, 5-level paging, and SMP (multicore), to name a few.
|
||||
Limine is a modern, advanced x86/x86_64 BIOS/UEFI multiprotocol bootloader used
|
||||
as the reference implementation for the
|
||||
[stivale protocols](https://github.com/stivale/stivale).
