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

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