I tried the updated procedure on my Sidecar JANUS drive and it seems to work.
I think I will wait for JANUS 2.0 before I trust it for sure though.

Since the first partition on my hard drive is for MS-DOS, I used the second
partition (JH0:) for JANUS FFS.

- ADISK reported partition 2 from cylinder 201 to 228 length 28.
- DPFormat reported starting at 0 and ending at 25.
- Watch early versions of Sectorama that can update to the wrong partition.
- In the Mountlist I used low=0 and high cylinder= 25 (not 201 and 228). 
- A normal JANUS partition and a FFS JANUS can be on the same disk, but they
  cannot both be mounted.  I guess I have to backup to floppies.
- Yes, 4-5 times faster for big file reads and writes. Thanks!   .....BJ

I recommend DJMount as the ONLY way to mount Janus drives. The V2.0 command
supports FFS. JDisk.device maps sector #'s and may do some things you are
not expecting. Also if you delete a patition with adisk and forget to update
your mountlist before you reboot..... *POOF*
