Existing Content

This website features content from the original Ardent Tool by Louis Ohland. In addition, it includes material from many other PS/2 and MCA-oriented websites. Namely:

Credit for the original content goes to the respective authors listed above. Thank you guys!

Aside from these major contributions, many other pages and resources were merged with the Ardent Tool. You should always find the name of the original author either directly on the page in question, next to the link that leads to it, and/or in the global changelog below.

If you are one of the original authors and you can't find your name anywhere, want to request some edits or content removal, please don't hesitate to contact us.

All direct email links present on these pages were either removed or replaced by an email form to avoid spam and email address harvesting. If you want to contact one of the original authors, please use the link that points to their website and look for contact information there, or contact us and we will point you in the right direction (if possible).

The website also contains various documents - such as technical references, brochures, patents, articles from various computer magazines, etc. Authors of these materials are either named explicitly on the page from where they can be accessed and/or are named directly in the material itself.


New Content

The MAD Edition also features a large amount of new content created by me - Tomáš Slavotínek. This includes technical explanations, tutorials, various text notes, board outlines (TS signature), schematics and other illustrations, pinouts, reverse-engineering and measurement results, hardware modifications, and more.

Many of the pre-existing pages from Louis Ohland and other authors were modified, moved, merged, or separated. Page changes range from simple typo corrections to complete overhauls. Some of the illustrations, tables, and other content were completely reworked. The main index and most sub-index pages were redesigned from a scratch to make navigation easier.

Despite all these changes we are trying to keep all existing external links alive by adding redirects and/or rewrite rules where needed. This includes links pointed to the original location of the Ardent Tool on Kevin Bowling's server.
