Yes, read protections are not that common (yet) for basic flash chips. The are very common where companies think they have to hide their data and/or algorithms (FPGA code, industrial/automotive microcontrollers), and X86 is moving towards this area pretty fast right now. :( -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner _______________________________________________ flashrom mailing list [email protected] http://www.flashrom.org/mailman/listinfo/flashrom
