I'm afraid this is still not clear to me. I created a new image with

dd if=/dev/zero of=some_image_file ...

When byteswapping is switched off and I partition this image (assigned
to a Hatari IDE drive), the byte order is not what it would have been with
a real Atari with standard IDE interface. Instead, the resulting byte
order is the one used by ACSI/SCSI.

"Auto" may be fine when dealing with existing images. But I often want
to create a new bootable (with a real Atari) image with Hatari. In such
a case it's important to have full control of the byte order. Otherwise
you end up with different results, depending on the original byte order
of the image.
