KBoot

KBoot is a general-purpose boot loader, which supports both BIOS- and UEFI-based PCs.

A short feature overview:

• Text and GUI menu interfaces
• Interactive shell
• Serial console support
• Ext2/3/4, FAT and ISO9660 filesystem support
• MBR and GPT partition support
• PXE network booting
• Linux and Multiboot OS loaders
• BIOS and EFI chain loaders (for booting OSes not natively supported, e.g. Windows)
• Custom boot protocol targeting hobby OS projects

KBoot also supports use as a second-stage boot loader on additional platforms, where its purpose is only to be able to load a kernel which uses the KBoot boot protocol. The platforms which support this are:

• QEMU ARM64 virt machine
• Raspberry Pi 3 & 4 (ARM64)

Current limitations:

• No FAT boot sector - cannot boot directly from a FAT filesystem on legacy BIOS systems.
• Floppy drives are not supported on BIOS systems.
• UEFI installation to disk on Macs is not supported (legacy BIOS, i.e. Boot Camp, is OK).
