Hi I need to perform a hardware reset on a KPD677H. The only account configured is the admin account and no-one in the organisation knows the password. I need to get this device back to factory default, I have trawled through various forums and the AVTech website but all articles appear to be for different motherboards. Does anyone out there have any idea how this could be done? Thanks in advance for any help you may be able to offer. Cheers
