Problem starting cpmish from an NC200 #68

Hello, First of all I would like to thank you for your work, it looks great, unfortunately I am not able to make it work on my NC200. After formatting a 720KB disk from the NC200, I dumped the nc200.img file with dd with the following command on an Ubuntu OS: dd if=nc200.img of=/dev/sdb (sdb is my USB floppy) I have extracted the image and compared it with the original file and they are identical. I inserted the floppy in the NC200 disk drive and pressed FUNCTION+R. The system starts reading from the floppy and displays the message: "Preparing Memory" But after a few seconds reading the disk it returns to the main menu. Would you have an idea what the problem could be?

Any help would be well received.

NOTE: I do not have a flash card inserted, but I understand that it is not essential to boot the system.

Hello --- that should absolutely work. Returning to the main menu is the normal behaviour when the system crashes so I suspect it's got through the boot loader and then something's gone wrong.

Unfortunately the floppy drive of my own NC200 has died so I haven't been able to touch this for a while. It's possible there's been a regression caused by other cpmish work. If so it's likely to be something very simple, but I can't debug it myself.

Did you build the image yourself or use the downloadable binary?

Thanks for answering. I downloaded the image already built. Unfortunately my floppy drive has died again, so I won't be able to do more research on the subject. Thank you very much too.
