I have two AMD64 (~amd64) Systems. Both have 8Gb memory installed as reported by their BIOS as well as by lshw. One is a somewhat older Opteron, the other one a recent Phenom II. But the output of 'free -m' differs significantly On the Phenom II there a total of 7738 Mb but on the old Opteron there a total of 6477 Mb only. The 2.6.36 kernel is configured nearly identical (just a different SATA driver). Has anybody an idea where this comes from? Many thanks for a hint, Helmut.
