Hi thanks for the reply but I have tried solution described in that link but no luck. I think the password is located in the EPROM so it cannot be cleared with playing with the jumper and the CMOS battery.

If there is anyone out there that could help me with the master password, please, it would mean a lot !!

Thanks !
