0011 Plug and Play (PnP) is a standard for peripherals which allows those
0012 peripherals to be configured by software, e.g. assign IRQ's or other
0013 parameters. No jumpers on the cards are needed, instead the values
0014 are provided to the cards from the BIOS, from the operating system,
0015 or using a user-space utility.
0016
0017 Say Y here if you would like Linux to configure your Plug and Play
0018 devices. You should then also say Y to all of the protocols below.
0019 Alternatively, you can say N here and configure your PnP devices
0020 using user space utilities such as the isapnptools package.
0021
0022 If unsure, say Y.

0028 help
0029 Say Y here if you want the PNP layer to be able to produce debugging
0030 messages if needed. The messages can be enabled at boot-time with
0031 the pnp.debug kernel parameter.
0032
0033 This option allows you to save a bit of space if you do not want
0034 the messages to even be built into the kernel.
0035
0036 If you have any doubts about this, say Y here.
