If you have been following the correspondence you will have seen
that my previous test was with VDISK as the _only_ alteration to
Glenn McCorckle's boot disk.
That had the same problem I have described.
He insisted that I use the disk _exactly_ as he posted it, so I
went back to the unaltered version, which is the one I last
posted.
But that didn't work either.

Fair enough.
But I feel that I have already given OpenDOS a fair and
reasonable test. No matter what variations of the setup I try, it
fails to work properly with Arachne in downloading HTML pages.
I will concede that I have had no problems at all with OpenDOS in
any other respect.
But since I decided to use it only for its alleged advantages
with Arachne, and since it hasn't delivered for me, I have
decided not to bother any further.

If...
Well, none of my five cards _do_ have those sockets, so that lets
out that possibility.
