  SVN rev 184327 on 2008-10-27 08:40:13Z by kato
  
  Improved IDE HDD geometry adjustment.  Previous code didn't work with
  certain ATA-6 drives including CF cards.
  
  The IDE geometry of the PC98 is calculated from the drive capacity.
  In addition to the algorithm in NEC BIOS, a variety of algorithms are
  provided by 3'rd party boards and BIOS hacks.  This change has
  implemented the three algorithms: IDE BIOS compatible mode, SCSI BIOS
  compatible mode and same way as the previous version.  The tunable
  machdep.ad_geom_method selects the algorithm.
  
  I have been using this change for a year with CF cards.
