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

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