 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.
