You most certainly can do this.  I have that controller, running in non-
translation mode, in an XT.  There is one jumper to move, I just don't
remember which one it was.

You can get a manual just by calling WD at (800) 832-8176 and asking for it.
 That's how I got my manual (which I promptly lost, or I'd look up the
jumper for you!).

The pitfalls would be that some BIOSs and/or DOSs don't like 26 sector
disks.  I don't know why this is, but if it works on your machine (it does
on mine) you should be OK.

>Will I be required to run Disk Manager on all my drives?

You should only need to run DM on the drives that need it (i.e. >32MB)
