Multiprocessor system VS one processor system

[Lanny Baron]

Olaf,
Our Server Boards (mainboards are those $19.99 boards you can buy at the
stores that sell the high-end 299.99 servers) are IA32 and our Server
Boards (except one tyan that uses the opteron) are Intel. 

Sun<tm> uses different architecture and have significantly higher costs.
