314 This can be useful if you are on a board which has a small amount
315 of memory or you wish to reserve some memory at the beginning of
316 the address space.
317
318 Note that you generally want to keep this value at or above 4k
319 (0x1000) as this will allow the kernel to capture NULL pointer
320 references.

788 Say Y here if you want to plug devices into your computer while
789 the system is running, and be able to use them quickly. In many
790 cases, the devices can likewise be unplugged at any time too.
791
792 One well known example of this is PCMCIA- or PC-cards, credit-card
793 size devices such as network cards, modems or hard drives which are
794 plugged into slots found on all modern laptop computers. Another
795 example, used on modern desktops as well as laptops, is USB.
796
797 Enable HOTPLUG and KMOD, and build a modular kernel. Get agent
798 software (at <http://linux-hotplug.sourceforge.net/>) and install it.
799 Then your kernel will automatically call out to a user mode "policy
800 agent" (/sbin/hotplug) to load modules and set up software needed
801 to use devices as you hotplug them.
