     True, the system is set up so that 32-bit memory shows up first in the
memory list.  But, that unfortunately doesn't mean that your 16-bit memory will
only get used if you run out of 32-bit memory.  Recoverable ramdisks, for
instance, tend to allocate memory from the end of the memory list.  Ensuring
that that 16-bit memory only gets used in dire situations can be complicated.

     If you do need more than 5-megs, then yeah, keeping your sixteen bit
memory is OK, just because it's currently the only option.  My main warning
goes out to those who have 5-megs of memory, 2 megs of which is 16-bit memory.
You will make money and have a way better system if you sell your 16-bit board
and buy 2-megs of the appropriate chips for your 2630.  I know.  I did it.
Trust me.
