[QUOTE="francior, post: 226731, member: 231128"] wallycharlo, i´ve read on german forums that 32 MB are ready for operating system (user memory) and 32 MB for internal system management (system memory). On model 7020, 96 MB built in memory, 64 MB for operating system and 32 MB for internal system management. Following data of my box: 1. top Mem: 23636K used, 6408K free, 0K shrd, 748K buff, 5872K cached Load average: 1.00, 1.00, 1.00 (State: S=sleeping R=running, W=waiting) 2. df -k ~ > df -k Filesystem 1k-blocks Used Available Use% Mounted on /dev/root 4096 4096 0 100% / /dev/mtdblock/1 1792 1368 424 76% /var /dev/ide/host0/bus0/target0/lun0/part1156259060 41868 156217192 0% /hdd On previous data (top command) if we add all values: 23636K used + 6408K free + 0K shrd + 748K buff + 5872K cached = 36664k (35.8 MB) we have the total memory for operating system. Then as you say, the operating system is copied to RAM memory : 36664k - 4096k (/dev/root) - 1792k (/dev/mtdblock/1) = 30776k (30,05 MB) Then i can now understand why the info memory menu says that the total memory is 29,2 MB (up to 30,05 MB are aproximately 800k on running processes). Anyway thank you all for your support. Regards. [/QUOTE]
