For those not into hacking with an iron, one can (of course) buy a
commercial product-

Most aftermarket 3.5" HD drives can be set by jumper to either pay
attention to the sensor hole, or to pay attention to the DENSITY SELECT
line.  The drives come set for the sensor active, because most floppy
controllers don't do anything with D.S.

Micro Solutions CompatiCard IV, along with its included CC4DRV.SYS, 
will sense what kind of disk you have and adjust itself, IF your drive
jumpers are set to ignore sensor.  Works very well; we have two in the
lab here.  

Micro Solutions has a real winner with the CompatiCard IV- you can connect
up to four drives inside, with one external; it handles 8" to 2.8Mb format,
auto-boot from *any* connected floppy, support for dual speed 5.25" HD
drives, support for cross-formatted 3.5" disks, and formatting disks
in the background while other programs are running.  

Micro Solutions can be reached at (815) 756-3411.  I have no connection
with them except as a satisfied customer.
