VxDs and related stuff help

Recommended Posts

Since its summer vacation and I don't have too much to do, I thought on giving it a try and learn how VxDs work and maybe try my hand on making some crude tutorial-like drivers.

As far as I've managed to find out, a DDK is vital as its name suggests, but the problem is that I haven't managed to find anyone who happened by chance to upload the 98SE DDK on the "internets" .

As for licenses and forum rules, I don't know how the DDK is classified as. Is it legal for it to be uploaded/downloaded, because, like with any other 9x-related stuff, M$ retired most of the stuff, so any Win98 DDK links are dead.

Also, except for the DDK, are there any introductory documentations/tutorials on VxDs ? I'm asking this because although I know C++ syntax and how to code something, I have absolutely no practical experience with drivers. I don't know their code-"anatomy", I don't know nothing on this issue.

A summary of my knowledge on this area would be wikipedia's article on VxDs and some general knowledge of how INFs work and their syntax, so I'm practically a "tabula rasa" .

Any help on the matter is highly appreciated.

Thanks!

Have you tried the Wayback Machine ? We'll see what we can do if you can't find anything. :whistle:

And, if I may, a couple of possible fields/projects in which to express your newly acquired knowledge/experience (the following would actually be useful ;)):

and more generally:

even if you are not interested in any of the above, the threads do contain some interesting/useful links related to VXD's. :)

About the Win 98 DDK:

Oh how sweet of MS - after 1MB of download, they cut the link off. :realmad: However, I do have a 98DDK on my HDD - it's a RAR archive (45,460,335 bytes) and the readme inside says it's synced to Windows 98 build 1998.6. If it's OK with the mods, I could offer a temporary HTTP link for direct download.

Perhaps this is also of interest although it is geared at not writing a driver.
