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.

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

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