The thing I am struggling with at the moment is getting sys$crmpsc_pfn_64 to work so I can use C to test the NVRAM.

I seem to have a problem with the service writing back the address and length, but I don't yet know why. Regards Rob

If you post a few lines of code, someone might spot the problem. I assume you are getting SS$_ACCVIO as return? So either return_va_64 or return_length_64 wasn't passed by reference (or wasn't long enough but you'd have to be really
lucky to pass in a 32-bit value that sat at the very end of a page ...)
