From Issue #48April 1998
Good introduction, I think, for those who is not familiar with Linux drivers at all.
Thanks a lot to the author. I enjoyed the article.
This article twice uses the term "protected mode" where it should be using the term "supervisor mode".
Protected mode is a mode of the Intel x86 processor which provides various protection features, such as memory protection and the ability to disable privileged instructions. Under Linux, all software runs in protected mode, but user applications run at a different privilege level to the kernel.
Of course this article is quite out of date (though surprisingly much of it is still relevant) but on this point it was wrong even back when it was written.
where is the sidebar & port table that were discussed in this article..?
This is not the magazine so there are no "sidebars" Check the links in the articles they have what you are looking for.
All the new OSs and windowing systems are oriented towards content consumption instead of content production.
