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. > 1. The 9600 baud suggestion is not guesswork, it is based on my > own experiences with 8250/16450 UART's and Arachne. 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. > 2.
