I recently had a problem with an old PC and onboard Trident Cyberblade i1 graphics. I tried all of the available drivers already in the driverguide.com database for the Cyberblade i1 but non of them worked! The Trident driver download site is not working either. Finally, I found someone else from a forum who used the VIA 8601 VGA driver instead for the Cyberblade i1. I have tried it myself as well, and all worked fine! It may not be the officially labelled Cyberblade i1 driver but it certainly works! Finally after 2 hours of searching!
I think this is the NT version of the driver.
