- fix bugs introduced in revision 1.48 which caused the default number of   cylinders, heads, and spt of each hard disk to be 1 instead of 0.  This   caused the BIOS to report the existence of the hard disks, even when   they were never configured.  The most obvious symptom of this problem   was "read multiple issued to non-disk" when a cdrom was enabled, which   happened because the BIOS tried to send hard disk commands to the CDROM.
