Hello everyone, I recently picked up a Dell OptiPlex desktop from Goodwill and it's locked down with an Admin Unlock prompt. I've already tried clearing the RTC/CMOS via a hard power drain, but the password persists in the EEPROM.

Could someone kindly assist me with generating a master password unlock code?
  • Motherboard Model: CTR92
  • Service Tag / Suffix String: 4B2V2H4-8FC8

Thank you so much for your time and help!...
