1. Partitions below 15.XMb are formated by DOS as 12-bit FAT, 4kb/cluster.
2. I fooled DOS with the following:
Modify the SYST IND in the Master Boot sector (Partition Table)
Replace there 01 (12 bit) with 04 (16 bit FAT)
Similar operation for BOOT SECTOR of the partition.
There you need to specify the cluster size (DOS 3.1 does not like to go
beneath 2k clusters, other allowed 1k as well).
Reformat the disk.... and thats it....
