what file should I use to update my cam

[DJJE]

I have a blue zeta cam and funcard2. What files should I use to update the cam, what version number? e.g. should this be a joker or ice cam update. When I put the cam into my cas2 it seems to think it is matrix revolution. Should I update it as a matrix revolution, if so what files should I use. Would this work or would it cause damage? I normally update my funcard with mach1 6in1 files and I use cas interface studio 6.6b. Currently, according to the common interface menu my cam has version 0.91 firmware. What software would this be and what is zap/no zap and should I be using it?

Thanks,

Darren.
