I upgraded my 486DX66 EISA system from 8MB to 24MB of RAM, but
I can't tell if the system ``knows'' about all the memory. I
looked at the output from `dmesg', `top', and `systat -vmstat'.
Dmesg and systat appear to report that 24 MB are present, but
top seems to be missing 8MB. So, how does one determine if
ALL the memory is being utilitized? Does top contain a bug that
makes the system appear to be limited to the ISA 16 MB boundary.
%dmesg
