+- Userspace programs as ELF files
+- mmap support
+- Framebuffer graphics (userspace can access with mmap)

 Paging is written for 4MB page support, since it is easier to implement. Downside of this is, each process has to use at least 4MB memory.

 This will create initrd.fat file. This is a mountable FAT32 initrd image. Once kernel initialization is complete, initrd contents are copied into /dev/ramdisk1 and it is mounted to /initrd. After that kernel runs the /initrd/shell ELF file.
