Write An OS (II) - OPOS

<h1>Write Your Own OS</h1>
<p>Hi ! This is the second part of my previous article <b>Write A Simple OS Now
!. </b> 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 <a href="http://www.geocities.com/cppresources/bt.zip"><b>bootable.exe</b></a>
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.</p>
<p>Below are a list of links I found over the time. Thought maybe you guys would
