An early Linux kernel boots on the iPhone

Summary

Hackaday shows OpeniBoot, which boots Linux 2.6 and BusyBox on early iPhones and the first iPod Touch. Touchscreen support was still missing. First and second generation iPhones were supported.

Ideas

  • OpeniBoot adds an alternative system to Apple’s boot chain.
  • USB serial provides a Linux console.
  • BusyBox delivers basic Unix tools.

Insights

  • A bootloader is the decisive lever for open operating system ports.
  • Early kernel support starts long before a usable user interface.

Recommendations

  • Back up device settings before installing.
  • Keep a tested recovery path.

Several Linux kernels run without a hypervisor

Hackaday presents Multikernel Linux, in which a host kernel divides up the hardware and starts further independent Linux kernels directly on bare metal. The project is called Multikernel Linux. It is not the historical microkernel-based MkLinux.

A modern Linux kernel still fits on a floppy disk

Action Retro trims Linux 6.14 and BusyBox down so far that a bootable system runs from a 1.44 megabyte floppy disk. The kernel used comes from Linux 6.14. The target medium holds about 1.44 megabytes.

Examining the Linux kernel safely with QEMU and GDB

Hackaday presents a script that downloads, configures and builds kernel sources and starts them as a debuggable Debian image under QEMU. It runs as a Python program. The kernels it produces can be built as Debian packages.
