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

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