v0.0.7

Added kernel memory protection via per-task page tables.

• Each task now runs in its own isolated memory space
• Programs can only access their own memory and malloc allocations
• Any out-of-bounds access or wild pointer instantly kills the task with SIGSEGV
• Kernel memory is fully protected from user-mode code

v0.0.6

Migrated file system storage from RAMDisk to physical disk (IDE)

The file system now uses persistent storage on the physical disk instead of RAM:

• Files are saved directly to the hard drive
• Data persists across reboots — all files and directories are automatically restored from disk

How it works

The kernel uses a separate physical disk for storage (not an ISO image).

Setup Instructions

For Virtual Machines (QEMU, VirtualBox, VMware, etc.):

1. Create a new virtual disk
2. Attach it to the VM as an IDE device at Primary IDE Master (IDE 0) — this is required for the kernel to detect it (temporary limitation)
3. Boot the kernel

For Real Hardware:

1. Ensure your target disk is configured as Primary IDE Master (IDE 0)
2. Boot the kernel

First Boot Notice

⚠️ First boot will take longer than usual — the kernel will automatically format the disk and copy all necessary files to it. Subsequent boots will be faster as this initialization only happens once.

v0.0.5

Support for user mode has been added.

You can now:

• Enhance system security: The kernel is protected from faulty application behavior.
• Run applications in an isolated space: Crashes in programs do not affect the stability of the entire operating system.
• Control resource access: The kernel manages applications' access to hardware and memory.
• Create a stable environment for programs: Applications run in a predictable and protected environment.

v0.0.4

Support for a graphics mode has been added to the kernel.

You can now:

• use the full resolution of your screen;
• draw at the pixel level.

v0.0.3

Multiboot2 support, UEFI also added.

❗Disclaimer❗
Since UEFI doesn't support the VGA buffer, it's recommended to temporarily use BIOS to launch the kernel.
This will be fixed in future releases.

v0.0.2

Now the kernel boots in Long Mode (x86-64).

Features:

• Support for 64-bit registers:

rax, rbx, rcx, rdx, rsi, rdi, rbp, rsp, r8, r9, r10, r11, r12, r13, r14, r15

• Ability to run user programs written in NASM.

v0.0.1

Kernel in Protected mode
