Which file is read by kernel to set its default system kernel parameters values?

Hi gurus

Could anybody tell me which file is read by kernel to set its default system kernal parameters values in solaris. Here I am not taking about /etc/system file which is used to load kernal modules or to change any default system kernal parameter value

Is it /dev/kmem file or something else.

Regards

The default values are hardcoded in the kernel, not read from a file, unless you count /kernel/genunix and other /kernel/* files in the list.
/dev/kmem isn't a file but the kernel virtual memory. The parameters are also there.
