	  Make sure your ROM base does not include any file-header

	  information that is prepended to the kernel.



	  For example, the bootable U-Boot format (created with

	  mkimage) has a 64 byte header (0x40).  So while the image

	  you write to flash might start at say 0x20080000, you have

	  to add 0x40 to get the kernel's ROM base as it will come

	  after the header.

	  help

	  Say Y here if you want to plug devices into your computer while

	  the system is running, and be able to use them quickly.  In many

	  cases, the devices can likewise be unplugged at any time too.



	  One well known example of this is PCMCIA- or PC-cards, credit-card

	  size devices such as network cards, modems or hard drives which are

	  plugged into slots found on all modern laptop computers.  Another

	  example, used on modern desktops as well as laptops, is USB.



	  Enable HOTPLUG and build a modular kernel.  Get agent software

	  (from <http://linux-hotplug.sourceforge.net/>) and install it.

	  Then your kernel will automatically call out to a user mode "policy

	  agent" (/sbin/hotplug) to load modules and set up software needed

	  to use devices as you hotplug them.
