It seems that the copying of the file has somehow gone wrong. The MD5 checksums differ; but copying the file fails but a dd of the file seems to work ok. I am beginning to suspect my Centos 6.9 is corrupt somewhere but ... odd if so as so much works ok.
Another possible answer is my laptop networking is screwed as the file download sizes are/were fine. Thanks to all for the help.

Before involving simh, please compare the md5sum of the disk image file that works vs the one that doesn't. - Mark _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
