It lives. After several days of trying all kinds of stuff and many many disk scans and checks it appears there was a corrupt dos file on the drive, overwrote all the dos files and the machine now boots up. Our best guess is the newer Linux machine wrote to the drive too fast as it's an old 120 meg hard drive. We tried one other drive to copy the files to and kept getting bad check disk results when we put it in the lathe. After switching to a 486 133MHZ machine we had laying around the drive copied OK and worked. Siemens tech support was very helpful, would have cost me about $300 for them to reload my drive with a generic Hyundai program had I need to resort to that. Ebay came through with a set of brand new DR DOS disks for $6.00. My computer guru now understands this thing pretty good and even knows a little German now too. I have 4 solid state 128M drives on order, drives that small seem to be discontinued already, back-ordered, I'll see what I actually get. I believe the BIOS in the lathe's computer will limit me to 500M.
