Hello,

no way to see (use ?) all available RAM (320MB) on SGI O2 with 2.6.10-rc3 (latest cvs)

Hardware => SGI O2 with 320MBytes in this way:
dimm 1: 32MBytes - dimm2: 32MBytes
dimm 3: 32MBytes - dimm4: 32MBytes
dimm 5: 32MBytes - dimm6: 32MBytes
dimm 7: 64MBytes - dimm8: 64MBytes

Firmware => "hinv" is reporting 320MBytes (OK, match hardware)

Linux Kernel (32 and 64 bits) => /proc/meminfo is reporting a MemTotal of 245436KB
"top" command is reporting same wrong value (more than 64MB missing)

where can I look for in sources to report/use all available RAM ?
can you help me ?

Regards
