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

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