BoltOS v0.1.0 — Initial Public Preview

BoltOS is a 64-bit operating system built from scratch in C and x86-64 assembly. This first public preview is source-first: build and run it with QEMU using the included scripts.

Highlights

• Custom BIOS and UEFI boot paths — no GRUB or Multiboot
• Higher-half kernel with ACPI, APIC, SMP, ring-3 userland, ELF loading, and syscalls
• GUI desktop with 24 apps, including a playable DOOM port
• Persistent storage, ATA/AHCI/NVMe support, EXT2 and FAT32
• In-kernel IPv4/TCP/UDP/DNS/HTTP/TLS stack and a browser with DOM, CSS layout, and JavaScript
