Also  for use with nitros9 you will have to change "TYP" to typ=21 for
nitros9 or typ=20
for use with original os9  level2  . If you are going  to use nitros9
best to change to new system
of descriptors , typ=20 is for 5 1/4 disks ether  for 40 trk  or 80 trk
for 3 1/2 drives is typ=21
I found that out  the hard way, I had about 250 disks I could not read
got error #249 which
is wrong type when reading with nitros9 and had to make compset boot 
with both  kinds of
descriptors.
Hope this helps,
Boris
