Freeze Project Bootloader

This document describes the GRUB configuration used in the Freeze Project operating system. The system uses a minimal GRUB setup to boot a custom kernel using the multiboot specification.

GRUB Configuration

The following is the exact configuration used:

set timeout=3
set default=0

menuentry "Welcome to the Freeze Project" {
    multiboot /boot/kernel.bin
    set gfxpayload=text
    boot
}

Explanation

Line	Description
`set timeout=3`	GRUB waits 3 seconds before automatically booting.
`set default=0`	Selects the first menu entry as default.
`menuentry`	Defines a boot option shown in GRUB menu.
`multiboot /boot/kernel.bin`	Loads the kernel using the multiboot standard.
`set gfxpayload=text`	Forces text mode instead of graphical mode.
`boot`	Starts the boot process.

How It Works

When the system starts, GRUB loads and displays a simple menu. After 3 seconds, it automatically selects the default entry and loads kernel.bin.

The kernel is loaded using the multiboot protocol, which allows FreezeOS to boot without writing your own bootloader.
