mi succede una cosa abbastanza strana, sia con windows, che non me ne frega nulla, sia con linux, che mi interessa troppo!

In pratica non parte il secondo processore!!!

Il server è un compaq prolian 1600 con due 400mhz e 128mb di memoria ecc (che a breve verrà upgradata a 384)

questo è il contenuto di /proc/cpuinfo

La cosa strana è che mi dice

SMP motherboard not detected.

ma è impossibile perché la macchina ha 2 processori e non 1! Sia SmartStart, il tool di gestione, sia allo startup compaiono ed inoltre fisicamente sono connessi alla macchina correttamente, insieme al relativo modulo VRM

Qualcuno ha qualche idea?
