changing to a question that's not a bug, some of those ressources might just be used by the videocard or something

Like sebastien says, if you use onboard video this gets assigned in bios andis not visible to the OS.

If not we can diagnose from there.

My on board video, only takes 64MB but not 256MB. I tried Ubuntu 8.10 and it recognized another amount, about 3.8 GiB and the free command is recognizing more or less 3900 MB more or less.
Which is te real one?

That's probably due to a discrepancy in what a GB is. The RAM manufacturer might mean 4,000,000,000 bytes whereas Linux probably thinks that is 3.725290298GB since it thinks a KB is 1024 bytes not 1000.

I have a Lenovo T500 with one memory bank of 2GB. The BIOS sees it as 2GB, Windows XP as 1.94GB (Task manager reports 2037708 KB which is roughly 1990MB or 1.94GB). Ubuntu 9.04 reports about the same : 1.9GB.
I know it is weird but like Micah said it is possible that the memory manufacturer does not use the same B unit... CPU-Z (a Windows XP utility) reports that I have a 2048MB memory on one slot, but that I have 1990MB of memory available only...

Can you help with this problem?
