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.

157    help
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.

180      This is useful if you cannot or don't want to change the
181      command-line options your boot loader passes to the kernel.
