135 Find out whether you have a PCI motherboard. PCI is the name of a
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.

160 help
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.

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