Seems that I found the proper BIOS chip for this laptop, and I have read BIOS backup, but I don't have clean BIOS file for it without password, because all the calculated codes that I have tried are not working on this model of the laptop.
Can somebody help me please to clear the password in this backup ?
Or maybe just the BIOS is corrupted somehow that it is not accepting the calculated codes that all normal Siemens laptops accept? So I downloaded a BIOS from Fujitsu Siemens website in ISO format, but I really am stuck on how to extract the BIN file from that ISO file ?
I managed to extract the original BIOS from the ISO file downloaded from Fujitsu siemens web, but the BIOS file there is 1.01 MB in size and I wrote it successfully to the chip, at least I hope that it will accept now the codes calculated from error code, because the Revision of the installed BIOS was 1.10 and this one downloaded from their web is 1.16
