It initializes bare-metal hardware and loads compiled operating system kernels from both legacy BIOS and modern UEFI firmware environments into a running state. The software utilizes a dual-firmware boot architecture and a pure-rust low-level runtime to handle hardware initialization and memory management without relying on standard library runtimes. It provides automated disk image packaging to combine compiled kernels and bootloader binaries into ready-to-boot FAT-formatted disk images for virtual machines and hardware. Additional capabilities include compile-time parameter macros for injecting settings such as stack size allocations directly into the binary, alongside custom entry point registration that defines specialized function signatures and automatically generates required startup symbols for execution. ## Tags ### Software Engineering & Architecture - [Bare-Metal Runtimes](https://awesome-repositories.com/f/software-engineering-architecture/pure-rust-implementations/bare-metal-runtimes.md) — Implements hardware initialization and memory management entirely in bare-metal Rust without relying on standard library runtimes. ### Operating Systems & Systems Programming - [Dual Firmware Layers](https://awesome-repositories.com/f/operating-systems-systems-programming/bios-firmware-interfaces/dual-firmware-layers.md) — Supports both legacy BIOS and modern UEFI firmware interfaces to load operating system kernels across diverse x86 hardware. - [Rust Bootloaders](https://awesome-repositories.com/f/operating-systems-systems-programming/kernel-core-internals/boot-startup-management/disk-image-bootloaders/x86-bootloaders/rust-bootloaders.md) — A pure-Rust bootloader that loads x86 operating system kernels from BIOS and UEFI firmware to start custom operating systems. - [Custom Kernel Booting](https://awesome-repositories.com/f/operating-systems-systems-programming/test-kernel-booting/custom-kernel-booting.md) — Supports operating system kernel booting, loading compiled executables from BIOS and UEFI firmware on x86 hardware.
