      If you intend to test everything that will be posted here, remember that an eprom supports up to 100,000 thousand recordings only.

              Its important to make a good backup. Make another two backups,compare them with a hex editor or some other file compare software to make sure both are the same,then post one of your backups. Not sure if the password can be removed though on this model by patching,you might have to use JTAG

                        What would be the laptop's initial problem, BIOS password?

                                        I managed to flash the patched dump with a good compare, but still the same melody with black screen

                                        When i put back the original dump the laptop work fine, but with password
