Description (partial)


Supervisor in higher slot# (slot 6 in 9-slot/6-slot chassis, or slot 8 in 13-slot chassis) boots up as active. 


Only known condition is larger read/access times for certain types of compact flash
cards which delays the reading and loading of the boot file into the DRAM during supervisor bootup.
There seem to be many other unknown conditions.
