http://ubuntuforums.org – I have an 8GB system with Ubuntu 9.10. And a puzzle. Ok, 8GB is: 8 589 934 592 bytes or 8 388 608 kilobytes (Got these numbers from google). Now, cat /proc/meminfo: MemTotal: 8192556 kB MemFree: 6278812 kB Buffers: 38832 kB Cached: 849552 kB System monitor rounds it down to 7.8 GB These are not rounding errors, please. So between 200-400 MB is gone somewhere (and my video is 1GB nvidia). Any ideas? BIOS is giving me the right info, i.e. full 8GB. L. (Hardware)
