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

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