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

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