SMP question on IBM x445

[k0ngi]

Hi
I have IBM xseries 445 server - 4xeon HT CPU, 4GB ram

after instaling gentoo, recompiling kernel i have:
Linux localhost 2.4.26-hardened-r2 #5 SMP
cat /proc/cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Xeon(TM) CPU 3.00GHz
stepping : 9
cpu MHz : 2994.039
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes

s acpi mmx fxsr sse sse2 ss ht tm pbe cid
bogomips : 5963.77

why only one processor ?

ok, i answer my question

recompile kernel, and enable option:
Processor type and features ->>
[*] Multi-node NUMA system support
[*] Multiquad (IBM/Sequent) NUMAQ support
[*] IBM x440 (Summit/EXA) support

and recompile, restart
