I just upgraded my MB from 1 to 4Gig of ram. The relevant part of lshw is
below. So I saw that and then I though I was ok. Then I went and did a cat of
/proc/meminfo
It says:
[root at saturn proc]# cat meminfo

Is the MemTotal the real total amount that the kernal sees? Is there a boot
option to increase it? I'm confus4ed because my bios sees the memory, and lshw
sees it.
TIA. lshw output below:
