 This jumper is to make the system aware of a 2nd INTERNAL drive. Not to make
 an external drive DF1:

 I also have 1 internal (DF0:) and 1 external (DF1: & DF2:) drive on my 2000.
 But instead of using 'AssignDev' I added a new entry into my mountlist. It
 looks like this:

/* MOUNTLIST file for allowing an external 3.5" (DF2:) to be mounted as DF1:
*/

DF1:       Device = trackdisk.device
           Unit   = 2
           Flags  = 1
           Surfaces  = 2
           BlocksPerTrack = 11
           Reserved = 2
           PreAlloc = 11
           Interleave = 0
           LowCyl = 0  ;  HighCyl = 79
           Buffers = 20
           BufMemType = 3
#

 Im not sure if this works better or worse than 'AssignDev' since I have never
 tested AssignDev. I do know that most programs I don't boot from (IE: I use 
 *MY* boot disk) will use this new DF1: -=- of course there are a few that will
 not. Like Marauder][, but then they dive into the deep dark regions where this
 kludge is unknown.

>Thanks in advance for any help.

 Im not sure if this is/was of any help, but your welcome!
