[syslinux] DOS/Freedos: Can't use mkfloppyimg.sh or mkdiskimage for +8M images

[Murali (முரளி கணபதி)]

The mkfloppyimg.sh script [
http://people.cs.uchicago.edu/~gmurali/gui/files/mkfloppyimg.sh] does the
following

Input: Old bootable DOS image, Size of New Image

* Use mkdosfs to create a new image of specified size
* Mount both old and new images
* Copy contents from old to new (using cp)
* Unmount both images
* dd the first 512 bytes from old to new EXCEPT bytes 11 to 61 (inclusive)
* Prints the C/H/S values to be used with memdisk [Gets the values for
mkdosfs output]

I have used it before to create a 10MB image, but that was a long while ago.
May be mkdosfs has changed its output?
