Hi all!

Just making this post for anyone with an NEC MobioNX MB12C or 20C who may benefit from this, in the hopes this comes up in their search for a solution.

As anyone who has tried this in the past will know - to restore/reinstall the system it requires a FDD with a proprietary port/cable in conjunction with the I/O adapter. Any HDD image simply written onto the hard drive will not work unless you use the boot floppy disk using this proprietary external FDD which are hard to come by.

However I managed to figure out a work around, and I have uploaded the .GHO disk image onto the internet archive which should work for anyone without the need for the FDD and boot floppy disk.

If you write this image to your hard drive using Ghost32 11.5.1 it should work straight away - i've tested this myself a couple of times with 2 different MicroSDs with IDE adapters so hopefully everyone gets the same result!

For anyone curious about how I got this to work:

1. I wrote the HDD image .GHO file onto the hard drive, in this case a micro SD with IDE adapter
2. I made an .ima of the 1st boot floppy disk and opened it up in winimage - I selected all the files in the floppy and dragged them onto the hard drive, making sure to not 'replace' any of the duplicate files on the hard drive but only copying across the files which are on the floppy drive but don't have an equivalent on the hard drive (it was around 10 files total from memory)
3. Plug the hard drive into the laptop and it should be good to go! I tested this a couple of times and on one occasion after a minute or so it randomly self-booted twice in a row, but after it ran scandisk it booted up again just fine and didn't have any issues from then on.

Hope this helps!
