[quote user="Tom Scharf"] 1. The password is the interrupt vector table? It randomly changes every time the code is changed? Yeah! No conceivable drawbacks there. 2. A mass erase nukes the INFO sector? Why, there is no reason anyone would want to keep that, is there? Well I could just read it first, but it seems I need to know the interrupt vector table of every firmware release ever released out in the wild. [/quote] I spend significant time for making universal PC BSL (for 2xx) that was BTW able to automatically use old vector (from previous build) for BSL password. At the end I gave up and switched to SBW. I agree with you that erasing calibration data (INFO A) because of bad BSL password is stupid.
