The main thing you are missing is the correct SAP for NetBios.
It should be F0F0 rather than 0F0F.
What is happening with your version of the access list is you
specify 0F with a mask of 01. The one says that the low order
bit does not matter, so both 0E and 0F would be a match and the
router records and stores the list as 0E0E 0101. If you change
the list to F0F0 0x0101 it will be intrepreted correctly.
