This is a toy Operating system.

I learn and try to create one to play.

Features

• Boots and displays "Hello, World!"
• 512-byte boot sector with correct signature
• Can be run in QEMU

Building and Running

make        # Build the floppy image
make run    # Run in QEMU (requires qemu-system-i386)

Verification

./check_boot.sh  # Check boot sector size and signature

Fix by Princess Liliya

The boot sector has been improved with:

• More efficient assembly instructions
• Proper stack pointer setup
• HLT instruction in infinite loop
• Correct boot signature (0x55AA in little-endian)

这是个玩具操作系统

狗子一边学一边做着玩的。

功能

• 启动并显示"Hello, World!"
• 512字节引导扇区，签名正确
• 可在QEMU中运行

构建和运行

make        # 构建软盘镜像
make run    # 在QEMU中运行（需要qemu-system-i386）

验证

./check_boot.sh  # 检查引导扇区大小和签名

银玫瑰公主的修复

引导扇区已改进：

• 更高效的汇编指令
• 正确的堆栈指针设置
• 无限循环中的HLT指令
• 正确的引导签名（小端格式的0x55AA）
