bootRS

A bootloader built in rust as a side project.

The bootRS project is organized as a Rust workspace containing multiple specialized crates that work together to provide bootloader functionality for both BIOS and UEFI systems.

I havn't pushed the test repo as some codes have open endpoints.(will update soon!)

Memory Configuration Architecture

The bootloader's memory management operates through a configuration-driven approach where kernels specify their memory requirements at compile time through the BootloaderConfig struct.

Physical Memory Discovery

The bootloader discovers available physical memory through platform-specific mechanisms and translates this information into a unified MemoryRegions structure.

Virtual Memory Setup

The bootloader establishes virtual memory mappings based on the kernel's configuration, setting up page tables and creating the virtual address space layout.

Boot Information Transfer

The bootloader passes comprehensive memory information to the kernel through the BootInfo struct, providing all necessary details for kernel memory management initialization.

Here's an overview:
