Hi,
this release version is 0.2.0.
Main Features
==============
grub multiboot loading
AHCI controller driver
TTY
Intel e1000 card driver
both elf static & dynamic linked binary loading
ext2 file system
real mode switching
ps2 keyboard driver
mouse driver
virtual and physical memory management
pci bus driver
multi-thread, multi-process
vesa driver
vfs
tcp-ip network stack
graphic driver
About file system
==================
In this version, I have fixed some bugs for file related operations.
now, you can create or delete files, directories. display file contents with 'cat' command.
write data into file with 'echo' command. the file system of shaun os is ext2, I made a basic
implementations. it is now compatible with linux os. you can create file in shaun os, and
verify its content in your linux box. File permission checking only work in
user level, no group and others, and also do not support symbolic.
About network
=============
currently, in this version, the network stack is over half completed. route, sockets api,
tcp, udp, icmp is done. the loop interface and unix socket are not implemented. You can use
ifconfig command to get/set interface ip address, and then ping this ip in your host os. in qemu,
you should be responsible for the network that is reachable.
About user interface
====================
when the kernel finished its initialization, it will load 'init' binary int /bin/ directory and
run it. in gfx mode, 'dsktp' instead.
the 'init' is a simple shell made for testing system apis. i have no time to write a shell with
full functionality. its source code is availiable on http://www.shaunos.com. if you have interest to
finish it, contact me.
the 'dsktp' binary if a simple graphic application made for testing graphic library api and
kernel GUI system. it displays keyboard input on screen.
the graphic library is integrated into libc.so. i write a small graphic library that can draw
window, label, edit box components on screen and compile it with libc together. the design rules
of it comes from MFC but written in C. read message, dispatch message in a loop system.
