The new VD0: works just fine for me. Assuming everyone has got the
obvious things like mountlist entries and having asdg.vdisk.device in
the CURRENT devs: directory (and with read permission!), one other thing
occurs to me.

There were two different versions of the original VD0: released. The
first was only available with the purchase of an ASDG RAM expansion, had an
8M limit, and checked for the presence of an ASDG RAM card. The second
was the shareware version, had a 2M limit, and did not check for an ASDG
RAM card. (Oh, one more difference: the commercial version was called
"vdisk.device" while the shareware version is named
"asdg.vdisk.device".)

Once I tried to install VD0: on a friend's 1M A500, and it failed with
the "device not found" error message. After a couple of hours of banging
my head against a virtuial wall, it suddenly occured to me that I was
using the software on my own Workbench disk thus I was using the
commercial, not the shareware VD0: software. As soon as I switched to
the shareware version, it worked perfectly. The commercial release was
failing on the A500 because it did not have an ASDG RAM expansion.
Perhaps the "device not found" was referring to the RAM card, not the
device driver?

So, my off the wall guess is that Perry forgot to take out the check for
an ASDG RAM card, and those of you that can't run the new version don't
have an ASDG RAM expansion.

Can anyone confirm this guess? Does it work for you withOUT an ASDG RAM
expansion? Does it fail for you WITH an ASDG RAM expansion?
