After doing some reading about device drivers and .ko files and drivers built into the kernel at compile time I was wondering what happens at boot time. Does the boot up process identify hardware and load the appropriate module (if there is one) for the hardware during the boot process (assuming that the driver is not already compiled into the kernel)? In the case of .ko files, when they are installed, how does the kernel know to load the module next time the system boots up? Is there some kind of lookup table during the boot process that searches for the .ko file of a new device when installed?

dmesg recognizes hardware. modprobe plugs in drivers. that's about all i know, so hopefully it helps –  Sepero Jul 17 '12 at 16:29
