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

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