My regular 3.5" settings are
BufMemType = 0
HighCyl = 79
39 is for a 360K disk.
And if the regular uses 0 for memory then you should be able to do too.
Unit should be read from the info file, but if you keep it then at least make it match to avoid confusion.
Always use SnoopDos to confirm what is (not) happening.
