my friend told me that if my os's running on, say a 256M RAM and a 128M RAM, mathematically, there should be 384M RAM, but actually, it's only got 256M RAM is working. Is what he said true?? why? thanks
If everything is working you get 384Mb. But some RAM does not work in some mb's, even if it is supposedly the right type (PC100 or whatever) and works in another mb. But RAM gone AWOL is a hardware problem, and nothing to do with Linux. You could try updating your mb's BIOS. Or see if your mb manufacturer has a forum or support page.
