does anyone know how can I check the bootvar on a 3725 router with IOS 12.4(19)? the "show bootvar" command doesnt work on this IOS.
Router#sh bootvar
^
% Invalid input detected at '^' marker.

Try this command "sh run | b boot".

thanks for your reply.
this router does not specify what file to boot in the config. it has 1 file in the flash and the config-register is 0x2102. normally it should load this only IOS from flash. however, it's constantly booting into ROMMON. I have to manually specify to boot flash:filename from ROMMON in order to load the IOS. I am curious what is the current boot environment. the show boot command is very useful. but I am finding it doesnt exist on this version. I am wondering if there is another way to display the same info.

Right. If the appliance does NOT have a boot statement in the "sh boot" or config then it follows the simplest of rules. It will run the FIRST IOS it sees from the list, from TOP TO BOTTOM.
