L2 cache problem

I recently converted an eMachine (T2798) into a Linux Redhat 9.0 Box. The computer has a Intel Celeron 2.70 GHz processor with a 128 K cache. I've had no trouble with installing or using redhat (per say) on the eMachine, however the cpu performance is much worse than I expected. When I checked out the /proc/cpuinfo file I fould the cpu cache was listed at 8 K instead of 128 K.

processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Celeron(R) CPU 2.70GHz
stepping : 9
cpu MHz : 2699.746
cache size : 8 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm
bogomips : 5387.05

It looks like redhat is only seeing the L1 cache and something is wrong with the L2 cache setup. However in the BIOS setup it shows the CPU cache size as 128 K. Also when I boot the system the log does not show anything about the L2 cache (while on other computer I have running redhat always at least metion the L2 cache size). I'm using BIOS version SR84510B.44T.0019.PO3 if that helps.

Has anyone had a similar problem, or have any ideas what could be going on? Thanks.
