We use "devtools", the predecessor of "idtools" to format
Newbury Data NDR 2190 hard disks. These are 190 MB unformatted,
144 MB formatted (you can only use 1024 of the 1224 cylinders).
Works just fine, only /etc/prtconf still displays "72 MB" on boot-up.
Has anybody  any idea how to fix this?

Yes.  Use a non-standard drive number when you low-level format the disk
with idtools and then use edittbl(8) to put an entry for that drive in
the /dgn/edt_data.  Do make a backup copy first :-).
