 136           bus system, i.e. the way the CPU talks to the other stuff inside
 137           your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
 138           VESA. If you have PCI, say Y, otherwise N.

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