; NOTES on Skew Factors:  Sector skew may be calculated or may be looked
;  up using a lookup table.  This is an assembly time option.  The format
;  Routines, however, need to have a skew factor entry for the purpose of
;  formatting.  If this skew factor is negative, this indicates that the
;  sector numbers on the disk are to be skewed by ABS(Skew) at format time.
;  When calculating skew for Read/Write, a negative number indicates the
;  sectors are to be read without skew translation.
