Hi! Sorry, I am not good on the linux set up. Anyway, I just upgrade
the server intel xeon from 3.2 ghz 512kbytes cache to 3.2 ghz 2MB
cache. I re-format and install redhat 8.0 again, but any how, I did not
see any different between between 5.12kbytes cache and 2MB cache. I
just check the CPU info and see it shows only 512 kbytes cache. So, how
I make the Redhat to support 2MB cache?? I check the BIOS and it shows
that:

L2 512 Kbytes cache
L3 2 Mbytes cache

So, any help would very appreciated.

Thanks!
