that makes me wonder about something I have several computers with 4GB of ram using the regular 32 bit kernel (non-PAE) and I see different amounts of ram, for instance: ]# free -m total Mem: 3286 ]# free -m total Mem: 3986
Probably PCI device memory. They start at 4 GB and go downwards (AFAIK most are not capable of 64-bit addressing so they have to be below 4 GB).
Now, many BIOS:es support "PCI hole remapping" (or whatever it's called), meaning that the memory that gets clobbered by the PCI devices can be remapped to somewhere beyond the 4 GB limit. However, obviously you'll need PAE or x86-64 in order to access this remapped memory.
