but do we need more RAM or more ROM?

i think Audya has 64mb RAM, but 360mb ROM

ROM i think is what holds the PCM sounds
RAM i think is just for the OS
please correct me..

so what i think we really need is more ROM, yes?

AJ, can we increase this?
is this what can be expanded via that bridge above soundboard?
or is this RAM? (please explain RAM too)
