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

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

182 Always use the default kernel command string, even if the boot
183 loader passes other arguments to the kernel.
184 This is useful if you cannot or don't want to change the
185 command-line options your boot loader passes to the kernel.
186
187 If unsure, say N.
