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
