installing object codes (*.o)
 

how do i install object codes (files that have an *.o extension) into the kernel??

Thanks.

It depends. If it's an object file you'd like to link to the kernel you need to copy it to kernel source, modify makefiles and then link it (using make).
But I think it's a driver. If so, you need to copy it to the right directory in /lib/modules/yourkernelversion/drivers and then just run
modprobe modulename
If itfails, run 'depmod -a' before.
