# i386 Nightloader | Folder Structure
|
|
|
|
## Legacy BIOS bootsector (bootsector/)
|
|
|
|
Contains one file, the source of the bootsector. This assembly program
|
|
must span the first 512 byte of a legacy Nightloader-booted Partition.
|
|
|
|
## Legacy BIOS Edition (legacy-boot/)
|
|
|
|
This edition of the Nightloader is made for older devices that predate
|
|
UEFI (or potentially for devices that have unreliable UEFI-support).
|
|
|
|
This folder contains the assembly sources to create the loader
|
|
partition which contains raw machine code that is loaded by the
|
|
bootsector and to which the control is handed thereafter.
|
|
|
|
### Source Folder Structure
|
|
|
|
#### drivers/
|
|
|
|
- acpi
|
|
Driver for the Avanced Control and Power Interface.
|
|
- pci
|
|
Driver for the Peripheral Component Interconnect. This is used to
|
|
first find and then interact with the builtin devices in a computer,
|
|
mostly storage devices, but also network cards, USB keyboards, etc..
|
|
- ahci
|
|
Driver for AHCI, the ATA Host Controller Interface (ATA meaning
|
|
(IBM PC) AT Attachment), storage interface. This is used to interact
|
|
with practically every modern consumer SSD and HDD. Older HDDs might
|
|
use another interface, but that's not of elevated relevance.
|
|
|
|
|
|
#### memory/
|
|
|
|
Memory Management functions, A20 line check, GDT setup and, some day
|
|
in the future, paging for add-ons execution. This also contains utils
|
|
like the allocators (arena, pool) used throughout the bootloader.
|
|
|
|
#### utility/
|
|
|
|
Helper functions that make it easier to write the other functionality
|
|
but don't fall into any of the other categories on their own.
