To-Do

• Fixing bugs, see issues: #3 #2
• Bring OS to work!
• ACPI commands: restart, add shutdown command
• Do a global bootloader upgrade
• Code library for using FAT32
• Code program for creating/displaying PGM files
• Option of creating backup diskette on setup process
• "Teach" the OS to determine the disk that installer is loaded from; encounter all possible data mediums for installing the OS; boot from disk that it has determined as the root of installed system — in other words, just its disk.
• Option of system restoring (in case the system parts are damaged)
• Code setup disk for OS, use compression algorithms
• User access control system, similar to Linux
• raa command - full administrator access
