|I'm not sure what your problem is, Keysha.|
As I understand it, you have a BIOS update which instructs you to disable the "Power On" password in the existing BIOS before proceeding with the update process. Is that correct?
Further, that your existing BIOS has no option to disable the "Power On" password, is that also correct? Well if that's the case, how did you manage to set this password up in the first place?
The option to disable it must surely be in there somewhere since no motherboard manufacturer I know of makes such a password compulsory.
