/*++
Routine Description:
Set the current volume's file system sub-type.
The volume stores the file system type on disk with a
strong bias to the FAT. However, this may not continue
in the future so a common interface to this type is supported.
The current on disk file system subtypes are:
UNKNOWN, no format done yet
12 bit fat
16 bit fat on a < 32M volume
16 bit fat on a >= 32M volume
IFS
OS/2 2.0 does not support this interface so we must set the
information via the MBR, NT will provide an ioctl to set this
information.
This information MUST be maintained to stay disk compatable.
This activity should only be done by format so this is
a protected method.
Arguments:
None.
Return Value:
FALSE - Failure.
TRUE - Success.
