An OS created by us from scratch

BrOS

This was taken up as the project in our Operating System course and has been implemented based on the paper in the link below http://nw08.american.edu/~mblack/papers/sigcse09.pdf

The project has been completed to ProjectD

To get the OS running-

1. Windows - You'll have to download Bochs 2.3.5. After installation, just double click on floppya.img

2. Linux - Run the command - "sudo apt-get install bochs bochs-x bochs-sdl" Go to the directory containing the floppya.img and run the command "bochs -f opsys.bxrc".

For development purposes (only for linux) - The following packages need to be installed -

• Bochs
• bin86 toolset: as86, ld86, bcc
• hexedit
• nasm

(sudo apt-get install bochs bochs-x bochs-sdl bin86 hexedit nasm)

Then go to the directory of floppya.img and run the following commands - chmod -x compileOS.sh ./compileOS.sh There maybe a chance that a new window open but is blank, then you have to type "c" in the terminal and press Enter.

The commands which work right now:

1. list a - to list all files present in floppyimg
2. exec "progname" - To execute the binary file in progname
3. copy "Fromfile" "Tofile" - to copy the contents of file Fromfile to Tofile (Tofile is a new file name)
4. delete "filename" - To delete all trces of filename in floppyimg
5. type "filename" - To display the contents of filename
6. create "filename" - To create a text file
