Question L2 Cache on Pentium I 233 MMX (i586)


I have a Pentium I 233 MMX machine with 1 meg (1024k) L2 cache, that runs as a fax server using hlyafax and Redhat 9.

Is there a way to let Linux know the board has that much L2 cache?

Under windows 20000 there is a registry tweak/hack for it, and it does make a noticeable performance gain in W2K.

Here is the current CAT /PROC/CPUINFO, there is no cache entry listed like for an i686 class processor. Yes the proc is overclocked to 250 (*83@3)

[root@a1300 root]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 5
model : 4
model name : Pentium MMX
stepping : 3
cpu MHz : 249.919
fdiv_bug : no
hlt_bug : no
f00f_bug : yes
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr mce cx8 mmx
bogomips : 498.07

So, nobody knows? Or is this not possible or required?
