MiniScribe 3425 a Second Hard Disk for WGS6386

[H.NGUYEN]

I have been trying to install a MiniScribe Model 3425 as a second
hard disk for my WGS6386 PC without success.  I notice that the
disk has several jumpers and a switch bank.  Unfortunately, I do
not have the manual for the disk to know what their functions are.
Should any one of them be set in a particular way for it to work
(as a second hard disk)?  If so, what is the correct setting?
