OSNews, Generic OSes BareMetal OS v0.4.9 has been released. Newest features are network communication via Ethernet as well as Memory allocation/free functions. BareMetal is an open source 64bit operating system for x86-64 computers. It is written in assembly, and applications can be written in assembly or C/C++. It's aimed at three target segments (high performance computing, embedded applications, and education). The kernel binary is still under 16 KiB as well!

I second that. GRUB can set up identity-mapped segmentation in order to load PMode code on x86, it's just strange that the new releases don't offer the option to set up some kind of identity-mapped paging and turn on long mode on x86_64. That would be the logical continuation of their previous effort. And much better that linking 32-bit and 64-bit code together in a bastard binary as in their current solution (loading ELF64 without activating long mode), and more generally being forced to maintain a 32-bit and a 64-bit codebase and make them work together...
