> It depends on the OS installed. For Unix-style OS you need to figure out the single user boot mode, which may mean passing "-s" or "single" in the boot arguments from the ROM. For VMS, if I recall correctly, you set the boot R5 register to 1. Then obviously the reset of the administrator user password is also OS dependent.
