I have a feeling it is just on or off with the SBIG driver.
MaxIM you set mode to Raw or Raw with RBI. In SBIG CCDOPPS it is just off and on check box.
I had a FLI with a 18803 for a while . You could set flushs etc.
So I think you are correct, i.e. normal routines to preflash with this driver. The SBIG RBI down loads much faster than the FLI in RBI mode. It seams to work without the extra flushs.
