OS not recognizing 2nd processor

[Tim Kelly <trkelly23@yahoo.com>]

 I recently added a 2nd processor and OS didn't
recognize it.

Computer: DELL 1550
OS:       Redhat 7.1
Kernel:   2.4.2-2

The BIOS tells me I have 2 processors but the OS
didn't pick it up.
The kernel install is a vanilla one from Redhat 7.1
and these are the kernel packages installed:
kernel-headers-2.4.2-2
kernel-pcmcia-cs-3.1.24-2
kernel-2.4.2-2
kernel-smp-2.4.2-2

And in /proc/cpuinfo I only get 1 cpu.
more /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 8
model name      : Pentium III (Coppermine)
stepping        : 10
cpu MHz         : 931.032

hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 3
wp              : yes

apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse
bogomips        : 1854.66

Is there a switch I need to set for the kernel/config
to pickup the other CPU?
