     This is the second part of my previous article Write A Simple OS now ! . This time its not just Hello WOrld , but a lot more than that. I have written a very simple basic kernel coded in turbo C 2.0 . It also has a simple $hell. Just follow the instructions in readme.now...And don't forget to vote ;-).

Write Your Own OS

Hi ! This is the second part of my previous article Write A Simple OS Now !.  Before moving on I must tell you that OPOS (for OPEN SOURCE OPERATING SYSTEM) is a project which is in its very initial stages started by me. I've uploaded the source files of the first release of OPOS. This release although , is no good for usage as an OS , it could serve as a good example for you if you are keen on coding your own OS. As PSC does not allow uploading of exe files you must download a small utility called bootable.exe from my homepage. This utility copies the boot sector code as well as retains the DOS file allocation  table of the disk making it readable from dos. So for installing OPOS you must download it.

Below are a list of links I found over the time. Thought maybe you guys would want to check them out. Please Vote.

2)NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com

Know of anyplace where I can get a multiboot loader? I'm not liking the fact that everytime I wanna do something, I have to load all of my stuff onto a floppy, and I have about three more empty partitions. I'd like to put one of them to use. =)
