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

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