 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.

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