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

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