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

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 KMOD, and build a modular kernel. Get agent
|
|
software (at <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.
