Features

• Monolithic Kernel: All drivers (VGA, Keyboard, FS) are embedded for maximum stability.
• Stack-Based Memory: Uses stack memory for filesystem and buffers to prevent memory corruption.
• Interactive Shell: Robust command-line interface with autocorrect.
• RamFS: In-memory filesystem for temporary file storage.
• Memory Management: Heap allocator with kmalloc and kfree functions.
• Process Scheduler: Process table and management with PID allocation.
• Advanced I/O: ATA disk driver with sector-level read/write support.
• Paging: Virtual memory with page directory and page table structures.
• Interrupt Handling: IDT-based interrupt management.
• CPU Detection: CPUID support for CPU feature detection.
• PCI Enumeration: Hardware device enumeration via PCI bus.
• Thread Safety: Spinlock synchronization primitives.
• Kernel Logging: Thread-safe kernel log buffer.
• Loadable Modules: Module loader interface for kernel extensions.
• Boot Parameters: Multiboot info parsing and memory map enumeration.
