I'm surprised that the system did that well considering you have 2x2GB DIMMs. There are two more things you can look at, /proc/meminfo will show what the system views as usable memory, and the output of dmidecode will show tons of stuff, but there will be one info block per DIMM which shows information on just that DIMM. I suspect you are getting a few MB of RAM shared for video, or something like that. The information in /var/log/messages will give more detail about how the memory is being allocated, but it's unlikely to lead to recovering more useful space. At least you have learned a lot about looking at your system, score one more for "things I learned while looking for something else." -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
