              I am willing to modify a BIOS to unlock it. Who's lucky?

                They are generators for all previous tags but not for this :/
                Best shot is to downgrade it and then use generator on old prefix / tag
                Of course if booting is possible not everything locked !!!
                Good luck

                  @Gobbla
                  As far as I've read, 8FC8 suffix is totally new and not an upgrade like 6FF1 (upgraded from 1D3B or 1F66), or BF97 suffix upgraded from 6FF1, so downgrading the bios will not do any good in my opinion, at least not for 8FC8.

                  @Karol
                  Probably your best bet is to register computer at Dell while still under warranty, then contact them in a few days to ask for the master password.

                        A couple of questions...

                        First, how would one go about figuring out a password for the bios if it is generated from a combination of the prefix and the suffix? I have the source code for the password generator that works for the older bios suffixes and I have looked at the code but I don't really understand everything that is going on there. I compiled the code and ran the app, of course it didn't work for the 8fc8 suffix so I have been checking back on this thread regularly. I have been a programmer of sorts for quite a while, but I'm only just now learning C, something I should have done many years ago but didn't. The question is however, what do you have to have and what do you have to do once you have the required pieces in order to figure out how to generate the password?

                        Second, to reprogram an EEPROM or similar chip, do you have to de-solder the chip from the motherboard and then place it into an external programming device, or can it be flashed somehow while it is still soldered on the motherboard?

                        I'm just trying to learn some of these things, at the same time I need to be able to access bios on this PC I picked up at an auction and currently I cannot. Any help or advice is greatly appreciated. Thanks.
                        A wise man once said that an error doesn't become a mistake until you refuse to correct it. I subscribe to that philosophy.
