I've put a DEBUG procedure at http://www.minuszerodegrees.net/ibm_xebec/ibm_xebec_st412_park_via_debug.htm
Definitely NOT recommended! Hard to say which is the lesser evil...I've found that you can also MANUALLY move that stepper arm to the end position when there is no power applied to the ST-412 drive.

I believe you. I've modified the code accordingly.I'd modify the DEBUG procedure to end with a jump to self, not a return to the DEBUG prompt. The reason being is that by going to the DEBUG routines again, an implicit invocation of interrupt 28H is performed as part of DOS's input code. If a caching routine hooks this, a subsequent disk access could result.
