I've been studying a program which uses Rainbow Technologie's Sentinel driver version 5.41.1 (32 bit). I've been disassembling the prog using IDA pro but I am not having any luck loading the sig file. I already have sspro.sig but this does not reveal any RNBOspro API calls. There are many tut's on Sentinel drivers but I can't seem to get past first base without the proper .sig file. Any advice?
Also, should I be disassembling sentinel.sys or the .exe file that runs the original program?

Hello Chad°|°ZTake .exe file first. If the .sig files does not find the api calls binary search in ida for the famous 7242 bytes & carry on with the fantasy...

Thanks for the response, Sope. It's becoming more clear every day just how far down on the curve I am (since I don't know what your talking about). Rather than ask a series of beginner questions, I'm off to the user manual for IDA and SICE. Every day things are making more sense. I haven't worked much with asm since the 8088 days. Back to the books!

Thanks.
