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.

RETURNS
       Zero.
