if you have uudecode and xdelta3, you can create one yourself:

1. create empty file with specified size
`dd if=/dev/zero of=512M_CF.null bs=16384 count=31689`

2. save below block as `512M_CF.uue` and run `uudecode 512M_CF.uue` to generate `512M_CF.xdt`

3. get/install/compile `xdelta3`, and run `xdelta3 -d -s 512M_CF.null 512M_CF.xdt 512M_CF.img`

then you should able to boot it on 86box(A drive with FreeDOS, and 512M_CF.img [CHS=1006/16/63] as IDE 0:0, press "a" key on XT-IDE boot delay prompt)
