aOS: A Simple i386 Kernel

Environment

• OS: macOS 14.2.1/(Linux?)
• Compiler: x86_64-elf-gcc, x86_64-elf-ld, x86_64-elf-as
• Emulator: qemu

Getting Started

cd aOS
make all           #compile the project
make img           #create virtual hard disk image hdisk.img
make run           #compile and run
make clean         #clean all .o files
make gdb           #debug

NOTICE: hdisk.img is not formatted, so partition_scan() and ide_init() (in kernel/ide.c) may occur error. To handle this problem, you can use fdisk to create a partition for hdisk.img

ToDo List:

• kernel thread support
• user process support
• syscall
• disk driver
• file system
• shell
