When I added memory beyond 64mb, I had to explicitly tell the kernel
how much memory I have. Without this, Linux did not recognize the
extra memory, and naturally it wasn't being used.
append = "mem=96M"
I have the above line in my /etc/lilo.conf, in the Linux stanza. This
added the parameter "mem=96M" to the kernel at boot time, so Linux
know exactly how much memory I have. Naturally, you'd need something
to the effect of
append = "mem=128M"
Sorry if that's too obvious, but it could save you a lot of trouble if
you've overlooked this. :)
Good luck,
Matt
