86F version increased to 2.10 - each side of each track now has its own offset in the table and each track now has its own number of extra bitcells;

Number of formatted sectors is now set to 0 every time the FORMAT TRACK command is issued;
The 86F writeback function now performs a fseek between the fread of the header and the fwrite of the track offsets table, so said table actually gets written to the file now;
PS/2 mouse now works on the Epox P55-VA;
Serial mouse now works again.
