NAME
guess - Tries to guess the configuration by comparing four dumps of the NVRAM. SYNOPSIS
guess DESCRIPTION
guess tries to figure out the position of the wakeup time settings in the NVRAM. Just run guess from within the directory, where the four NVRAM dumps at stored as "31.23.59.59+", "11.12.13.14+", "01.00.00.00+" and "01.00.00.00-". The file names denote the wakeup time, you have to set manually, before dumping the NVRAM: <DD>.<HH>.<MM>.<SS><status> <DD> = Day of month <HH> = Hour <MM> = Minute <SS> = Second <status> = wakeup enabled (+) or disabled (-) SEE ALSO
