The BIOS does not have any info about L2 cache accept for
enable/disable
switch.
I noticed that after the POST message in the table of all installed
devices it said CPU 1.7 GHz... Memory installed 256 M (RAM) and
CPU cache: NONE.
I have upgraded the BIOS on the system and now it says 128K, as it
should, according to CPU specifications.
Mark tells that /proc/cpuinfo reports L1 cache size (which I assume is
8K+12 K in my case, even though I do not understand what that means)
But how to check that L2 is operational?
For windows I have ASUSprobe software, which after the BIOS upgrade
started to report that CPU has L2 cache, but it reports it regardless
of BIOS switch(enable/disable) as if program simply reads the CPU
specifications. (Before BIOS upgrade it reported 0K L2 cache.)
The question I have is: Is it possible to tell whether or not
the kernel sees the L2 CPU cache and its size?
Thank you very much for your help
