With 2.4.1-ac3, I came up with the following different memory readings for
both a Pentium 166 and an Athlon 750.
Pentium 166: (96MB RAM)

Athlon 750: (128MB RAM)

Last year, when I had 32MB of memory in the Pentium 166 machine, the amount of
'reserved' memory seemed lower. It almost looked as if the amount of reserved
memory is a fraction of total available memory.
Is there a way I can 'regain' this memory from the system, especially in cases
when there's only 32MB to work with?
Thanks,
Byron
