SMP machine

[rhn apacse fedex com]

Hi there,

Could anyone advise how we are ensured
the multiple CPUs 
in the SMP machine are used by the system?
I'm running
RHEL 3AS on a Compaq ProLiant ML370
(dual 3.2GHz CPUs
with Hyper-Threading). The dmesg only
shows the CPU#0 is
"Intel machine check reporting
enabled". How do I know
the another CPU is used? The system
monitor only shows
CPU in total, the top command also shows
the total only.

If the second CPU is not enabled or
in use, how would I
do to make it working? 


Thx in advance.
