[net.micro.amiga] recoverable ram disks

You hit the line eater with a mighty bash! --more--

I was wondering, can anyone discuss what happens to their recover-
able ram disk whenmemory starts running low? Or in general, what
is supposed to happen to the normal ram: when memory starts running
out?

My purpose is I'd like to compare the way ASDG handles the situat-
ion with the way other's a chosen to handle it.

With the ASDG recoverable ram disk, the document I received states
that if fast ram gives out when the ram disk tries to expand, some
chip memory is allocated instead. While any ram disk data is loaded
into chip memory, the asdg driver monitors fast ram waiting for a
space large enough to free up. When it does, the driver swaps the
track from chip ram to fast ram and frees the chip ram space.

They say (I paraphrase): ``Chip ram should be for graphics - not
wasted on ram disk'' With 2 megabytes of fast ram and only 512k of
chip ram, I think they're right.

So? How does the other people purporting to have a recoverable ram
disk address this issue? Do they at all? Are there any other re-
coverable ram disk drivers around at all? This (recoverable ram disk)
seems to be a really important item. Let's have some discussion on
this topic (enough on the 68030).

My opinions are.
