NAME
       ata_std_bios_param - generic bios head/sector/cylinder calculator used by sd.

SYNOPSIS
       int ata_std_bios_param(struct scsi_device * sdev, struct block_device * bdev,
                              sector_t capacity, int geom[]);

ARGUMENTS
       sdev
           SCSI device for which BIOS geometry is to be determined

       bdev
           block device associated with sdev

       capacity
           capacity of SCSI device

       geom[]
           location to which geometry will be output

DESCRIPTION
       Generic bios head/sector/cylinder calculator used by sd. Most BIOSes nowadays expect a
       XXX/255/16 (CHS) mapping. Some situations may arise where the disk is not bootable if this
       is not used.

       LOCKING: Defined by the SCSI layer. We don't really care.

RETURN
       Zero.
