• Multi-OS Support - Boot Android, Linux, or other systems
• Hardware Initialization - Full hardware detection and setup
• Graphics Support - VESA graphics mode with custom UI rendering
• File System Support - FAT32 file system access for kernel loading
• Secure Boot - Optional secure boot implementation
• Recovery Mode - Built-in recovery environment

Technical Specifications

• Architecture: x86 32-bit protected mode
• Memory Management: Paging enabled with 4GB address space
• File Systems: FAT32, EXT2/3/4 support
• Graphics: VESA 2.0+ compatible, 32-bit color support
• Protocols: Multiboot2, ACPI, SMBIOS support
• Security: SHA-256 verification, secure boot options

Building from Source

Prerequisites

• NASM 2.15+ (assembler)
• GNU Make 4.3+
• GCC (for toolchain utilities)
• QEMU 6.0+ (for testing)

Installation (Ubuntu/Debian)

sudo apt-get update
sudo apt-get install nasm make gcc qemu-system-x86 xorriso grub-common

Installation (Fedora/RHEL)

sudo dnf install nasm make gcc qemu-system-x86 xorriso grub2-efi

Build Process

git clone https://github.com/FMZNkdv/ABL.git
cd ABL
make all

This will generate:

• build/abl.bin - Raw binary image
• build/abl.img - Floppy disk image
• build/abl.iso - Bootable ISO image
• build/abl.efi - UEFI application (if supported)

Deployment

Testing with QEMU

make qemu
make qemu-uefi
make qemu-vga

Installation on Physical Hardware

sudo make install-usb DEVICE=/dev/sdX
make iso && cdrecord dev=/dev/sr0 build/abl.iso
