Post subject: | Shaun OS 0.2.0 released |
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. WHAT YOU DOWNLOADED =================== Code: shaunos ├── bin │ ├── cat //cat command ported from bsd │ ├── chmod //chmod command ported from bsd │ ├── dsktp //a simple window UI, first app to run in gui mode │ ├── hello //just print hello world, dynamic linked elf binary │ └── init //small shell, first program to run in console mode ├── floppy.img //a floppy image with grub and kernel installed ├── lib │ └── libc.so //libc ported from bsd,including system call, graphic library ├── LICENSE //license file ├── README //you see now └── root ├── arrow.bmp //mouse bitmap, for gui mode └── bk.bmp //desktop background file, you can replace it with whatever you //want, make sure that it is 1024 x 768 pixel. RUN WITH QEMU =========== Download tar file here or Download zip file here 1, download tar file and extract it. 2, cd shaunos directory 3, create a hard disk file with qemu-img, 1G size is enough Code: qemu-img create -f raw hd.disk 1G 4, in linux box, format hd.disk with ext2 file-system Code: mkfs.ext2 hd.disk this command will ask you 'Proceed anyway? (y,n) y 5, mount hd.disk on /mnt Code: mount -text2 -oloop hd.disk /mnt 6, copy 'bin','lib','root' directories extracted in current directory into /mnt/ Code: cp -r bin /mnt cp -r lib /mnt cp -r root /mnt 7, unmount disk file from /mnt Code: umount /mnt 8, run qemu with follow command: Code: qemu-system-i386 -fda floppy.img -boot a -monitor stdio -drive id=disk,file=hd.disk,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0 9, in console mode, enter password: shaun 10, enjoy! RUN WITH VIRTUALBOX =============== 1, download shaunos-vbox configuration file 2, unzip the file you downloaded 3, cd shaunos directory 4, open shaunos.vbox using your favorite text editor 5, modify following two lines, specify your location path of vmdk and floppy.img, these two file are under the current directory and save it. Code: HardDisk uuid="{3464c236-39e3-43cc-a4a5-94f206895a72}" location="C:/Users/Shaun/Desktop/hd.vmdk" format="VMDK" type="Normal" Image uuid="{cae57606-b513-4f56-86c3-154174e92301}" location="C:/Users/Shaun/Desktop/floppy.img" 6, open virtualbox manager application,in FILE->Preferences->Network->Host-Only Networks->VirtualBox Host-Only Ethernet Adapter setting tab, set Adapter IPv4 address to 192.168.92.1, IPv4 Network Mask 255.255.255.0, disable DHCP service, click OK. 7, double click shaunos.vbox file, or open it with your virtualbox manager application. 8, enjoy. ping 192.168.92.140 from host os. this ip address is the default address of eth0 RUN WITH VMWARE ============ my vmware version is 12.1.0. 1, download my vmware configuration zip file shaunos-vmware 2, unzip it 3, cd shaunos directory 4, open shaunos.vmx using your favorite text editor 5, modify following two entries to the correct path of your environment. these two file is under the current directory. Code: sata0:0.fileName = "C:\Users\Shaun\Desktop\hd.vmdk" floppy0.fileName = "C:\Users\Shaun\Desktop\floppy.img" 6, double click shaunos.vmx, and run this vm. 7, enjoy! if you want to explore more? boot into graphic mode? visit here |

Hi Shaun! I'm impressed, amazing work. You got a bunch of great features. Where can I find the source though? I struggle a little with the dynamic library loading and it would be great to see how someone else does it. Also would be nice to have a boot-ready iso image, so we can play around with it Greets |

Hi, max i have updated the post, and add steps about how to run it on vmware and virtualbox platform. i take a different way to implement elf shared library loading, put the loading phase in kernel mode, without need of /lib/ld-linux.so. finally, i feel sad to say that the source code is not available now. |

Great work! I have already been thinking you're done with OS development. Turns out, you've just been silent. I'll test it soon. Good luck! |

It seems really buggy at least on VirtualBox. I just done "cd bin" and then "ls" and it popped out 4 "KERNEL ERROR" messages. |
