:I've got an annoying problem.  I've got an Amiga 500 with A501 ram
:expansion.  I've got ASDG's recoverable ram disk.  It doesn't recover!
:I use Manx Aztec C 3.4a, and I like to put everything on ram disk when
:I work- includes (the ones I need, anyhow), compiler, assembler, linker,
:c.lib, and microemacs; in addition to my most often used cli commands.

:But when I've got a lot of stuff in vd0: and crash the system
:(which I manage to do quite often), the recoverable ram disk is no

	Simply that the A500 also uses FASTMEM when available rather than
CHIP ram.... If you fill up VD0:, rebooting the computer overwrites some of
it.  You need to make your VD0: small enough so the stuff the system puts in
FASTMEM on boot (before you remount VD0:) doesn't overwrite it.

	Additionaly, if you tell VD0: to be so big, and it runs out of memory,
nasty things will happen.

	Better make it smaller.... 256K maybe.  VD0: was designed for people
with larger expansion memories anyway.  Mine is approx 1 Meg with a 2 Meg
expansion.
