System sees only 65M of memory

[Art Edwards <edwardsa@thuntek.net>]

I just purchased two Athalon-based systems, each with 768M of ram.
However, under debian (potato runnin kernel 2.2.17) the OS sees only 65
M of memory. I have tried to use the append command

mem=768M

but it still sees only 65 M? 

Does anyone have any ideas?
