kato 5b1802a644 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.
