If you force re-initialization of whole ide1 interface, you could.
You maybe able to access hdc, however tweaking with DMA setting 
there after can cause a mess.  You probably end up using the 
device in PIO mode.

I worked on it over a year ago with my TP570 with UltraBase,
and was able to get 2nd hard disk drive recognized.  But
repeated warm swapping was unstable.

Writing all this reminds me that there were things that I didn't
figure out, such as setting up hdc in CMOS.
