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.
Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come
out every day, so no prevention program can catch 100% of them. For your own safety, please:
Re-scan downloaded files using your personal virus checker before using it.
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

mmm...you know you can get the source to any of the linux kernels right? i don't know why you would post the source to 0.0.1 considering they're on like 2.5.2 or somewhere around there... (If this comment was disrespectful, please report it.)
Yes of course you can get all the linux kernels , but this ones been coded by linus himself. For beginner the code is real good to understand how a kernel works !!!! (If this comment was disrespectful, please report it.)
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. =) (If this comment was disrespectful, please report it.)
Thanx a ton man. I am making an OS and this is gonna help tremendously. ;) Again thanx. I may email u with some questions. (If this comment was disrespectful, please report it.)
Very cool! Now all you need to do is add multitasking, a GUI, full mac/nix/doze compatibility, a few other things, and you'll be VERY rich! (If this comment was disrespectful, please report it.)

hi, i could not compile the source code given, i have a main.asm assembler file when i compile with tcc with given options. And i could not understand why u make us to try to find the source code for boot12.bin and why u make us to load os with bootable.exe. We can load with dd, partcopy etc.
Thank u but i say: Dont be gates, be linus (If this comment was disrespectful, please report it.)

Hello everyone - I am trying to get rid of my old GeoCities page (that hosts the BootStrap Tutorial) but I don't want people to lose the resource. If you could please change the link to point at its new permanent home http://www.omninerd.com/2005/11/05/articles/40 it would be most appreciated. I've rewritten the narrative to be more detailed since it was first released. Thanks! (If this comment was disrespectful, please report it.)
Did anyone actually manage to compile the source? I always get errors no matter what I try. I think there is a bug in the syssrv.c code. (If this comment was disrespectful, please report it.)
good code for begineers but how about booting from medium other than floppy such as hdd,removable media,etc. Could u offer a modified bootsector? (If this comment was disrespectful, please report it.)
dude your awesome i give you props. (If this comment was disrespectful, please report it.)
