Discrepancy In Reported Memory Between (BIOS ,MCC) & (/proc/meminfo, kinfocenter)
Linux version 2.6.24.5-desktop586-2mnb (qateam@titan.mandriva.com) (gcc version 4.2.3 (4.2.3-6mnb1)) Mandriva 2008 Spring KDE 3.5.9
I have just upgraded my system from 1 to 2 GB or memory. System BIOS indicates this and the mandriva control center in detected hardware indicates 2, one Gig memory modules installed.
My question is why does kinfocenter (and /proc/meminfo) only reports 884 MB of total physical and bootloader only found 896 MB when BIOS and MCC indicates 2 GB RAM? Is my system only using 884 and not utilizing the additional memory I upgraded?
In the Mandriva control panel bootloader menu under Main option submenu Advanced
I tried to put the correct amount of memory in "Precise RAM size if needed " field box with no avail.
I'm assuming kinfocenter gets it info from /proc/meminfo because 905564 KB is approximately 884 MB

Answer: Installed kernel which supports memory greater than 890 MB

Reason: Found Solution... Installed Kernel which utilizes memory greater then 890MB
When I had 4GB RAM on my Mandriva 2008.1 Spring machine, it was detecting 3.xGB(Which was genuine I guess). But after I removed one 2GB module, my total memory is 9xx MB!
Strictly speaking, the limit is 1 Gig - has been a kernel default for a long time. The "missing" bit is reserved for the the kernel to use.
That naming is peculiar to Mandriva - not a (general) standard indicating a non-highmem kernel.
