A question for all you floppy controller experts out there.
Is there a way to support > 2 floppy drives on a single
Western Digital WD1003-WA2 controller. The controller
is installed in a Dell '286 box and currently has 2 5-1/4"
drives on it. We want to a a 3-1/2" drive but would like to avoid
having to buy another controller card. I can get the motor on the
drive to turn when accessing drive "D" using a "driver.sys" device 
driver and playing with the drive select jumper on the disk drive
(drive connected to the untwisted section of cable with an additional
connector), but DOS returns a "Not Ready Error". I don't have 
documentation that describes the controller card so I was wondering 
if there wasn't some jumper I could  move to make this thing sane.
I'm not adverse to using an untwisted cable and correctly setting the 
drive select jumpers on each drive (as Shugart intended). 

Thanx in advance.
