Hi, I'm wondering if there's a method for doing any of these 1. Check what's the physical memory available. free -m shows ~768 mem but I was sure that I had 1G of memory in there. 2. I check the kernel and it seems like the 4G split is in effect so it should map / correctly recognise there's 1G of Mem there. Is there any way to check besides opening up the machine to look at it physically??
