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

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