Now i developed a new version for multiple multihead adapters. U can render over 16 adapters which can have 16 heads per adapter.
The currend used irrlicht has the version 0.14 but i planned this patch for the newest version of irrlicht. (but The current version has no 32 bit indicies and so on. it is a little bit hard to adpated all the features)
U can download the irrlichtv014 multirenderer source at my project site
http://dev-delight.sourceforge.net
the engine enummerate all the adapters if u coose the multihead driver.
u can set the right adapter / head with with the viewport function.
updates follows =)
In some cases the dx device was not correctly reset after the app termination.
Tested on 4 monitors with 2 cards.
nvidia 7600gs pci express
nvidia 5200 FX pci without express =)
i hope the code was usefull...
here the helloworld tutorial for multihead support
