	  Find out whether you have a PCI motherboard. PCI is the name of a
	  bus system, i.e. the way the CPU talks to the other stuff inside
	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
	  VESA. If you have PCI, say Y, otherwise N.

	  Unicore processors can not fetch/store information which is not
	  naturally aligned on the bus, i.e., a 4 byte fetch must start at an
	  address divisible by 4. On 32-bit Unicore processors, these non-aligned
	  fetch/store instructions will be emulated in software if you say
	  here, which has a severe performance impact. This is necessary for
	  correct operation of some network protocols. With an IP-only
	  configuration it is safe to say N, otherwise say Y.

	  This is useful if you cannot or don't want to change the
	  command-line options your boot loader passes to the kernel.
