Rewrite notice

Important

This project is not dead. Check out the rewrite/0.2.0 branch.

We decided to rewrite PRosBSD from scratch, as the current version (0.1.0-dev) in the dev branch is memory-unsafe crap full of UB's. There is no point in continuing to support it further. The rewrite/0.2.0 branch will be merged into the dev branch as soon as these features are implemented:

• VGA Text
• printf
• panic
• Debugging macros (e.g., DEBUG_*)
• Debug over GDB
• GDT
• IDT
• Normal heap
• Memory map
• Paging
• CMOS
• PS/2 Keyboard
• PIC Timer
• Grub
• KShell
• PATA PIO driver
• Some filesystem
