No whole phisical memory, no 64bit
My Dell N5040 notebook had 2GB phisical memory. Yesterday it was added more 2GB.
Code:
root@Microknoppix:/home/knoppix# dmidecode -t 17
# dmidecode 3.0

But Knoppix see only 2,9G.
Code:
root@Microknoppix:/home/knoppix# free -h
total used free shared buff/cache available
Mem: 2,9G 699M 743M 254M 1,5G 1,9G
I tried "knoppix64", "mem=4096M", "nozram" (separate and together) cheatcodes, but nothing changed. While SystemRescCD in 64bit mode saw 3,7 GB memory.
Actually I suppose what is the problem but it does not help me since I cannot resolve it. When I boot Knoppix in 64bit mode, it boots in 32bit mode... Since with "knoppix64" cheatcode I get:
Code:
knoppix@Microknoppix:~$ uname -m
i686
knoppix@Microknoppix:~$
While using SystemRescCD in 64bit mode I got "x86_64".
I run Knoppix 7.6.1 from ISO file.
