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.
