I downloaded one from somewhere. I can't remember where. It's shareware and
costs I think about 20 dollars. It's called VFD. It's an MS-DOS program that
requires a lot of lower memory(600k), so you have to boot without network,
SCSI, just about anything. It isn't easy to use, but does the job well. The
programmer's name is Bob Williamson. He's on Compuserve at 76570,2752.
Hope this helps.
