Which of the following happens
(1) mkfloppyimg.sh is failing and not creating the image
(2) memdisk is not booting the created image
(3) memdisk is booting the image, but DOS complains while booting.

Also what is the exact error message you are seeing?

I am assuming you gave the "floppy" and "c/h/s" values to memdisk, since
otherwise you would not have been able to boot a 8MB image.
