8b6a5e91bb The INT 1B BIOS call is used to obtain geometries of SASI/IDE hard
drives.  Some IDE cards don't set propler information into BIOS work
are and their sector size were always recognized as 256 bytes/sector.

e9b13dd6ec Added PC-98 HDD boot manager. The boot0 is the `IPL' which occupies
sector 0 of a disk and boot0.5 is the `boot selector' which starts
from address 0x400.  The IPL loads boot0.5 and boot0.5 loads bootblock
of a slice.

The boot manager stuff was developed by me (kato) with Borland C++,
and then, translated into bcc in the ports collection by Nokubi-san.
After that, boot0 has been translated into gas with the .code16
directive by Takahashi-san (nyan) and boot0.5 has been rewritten in
gas by me.
