ITT: Shills. Normal as they reply whenever anyone asks this, but the DaosSoft guy stands out as something special at best this is a GUI on Hirens tool, at worse it’s malicious. Regardless, it claims to do nothing but recover credential in windows (W10 is not supported) and the reliance on a boot disk ignores the possibility that the locked bios will only boot from HDD not to mention what the TPM will think. OK rant over, now I’ll help. The challenge/response code thing they do may work, but if that is your chosen route try calling Toshiba first and explaining, odds are better they will give you the codes as they are selling the whole laptop division but while rules may be relaxed, good luck finding a number to call or website still live. Check out the service manual, here is the one for the z930, they are very close models, but this is informational, get one for your exact model(s) before doing anything. Not only are the board schematics there to facilitate your jumper placement, but they reference procedures for rewriting bios and eeprom (likely the IC you were looking for) and other wizardry in detail, pardon me for forgetting, its #500 pages and a great document AND TOTALLY FREE. The Bios rewrite is literally a one click process but Iwill admit the instructions are rather cryptic probably illuminated by reading the reast off the document https://www.manualslib.com/manual/813546… Actually, here’s the manual for yours. https://www.manualslib.com/manual/819245… Didnt look at the diagrams, but overheard the jumpers you may need are “near the ram”. happy hunting. Armed with that a DIY Loopback or whatever you may have success, but personally I would use the manual to feign a mobo replacement using the rewriting function of the various modules eeprom bios ec/kvc (fairly sure that is the specific name Toshiba use for the eeprom) but spoofing the DMI with that pulled from a fresh identical system. Read more into the role of the DMI, I’m hazy but Ithink it could help “NOTE: When replacing the system board, be sure to execute the following procedures.

  1. Before replacing the system board, execute subtest03 “DMI information save” in 3.4 Setting of the hardware configuration in order to save the DMI information from system board to floppy disk.
  2. After replacing the system board, execute the subtest04 “DMI information recovery” and subtest08 “System configuration display” in 3.4 Setting of the hardware configuration in order to copy the DMI information and system information from the floppy disk” Appologies for length, a link to the manual would have dont just as well. Please update us on this, these bios locks are a peeve of mine and I’d love to get it nailed. Best of luck Soni
