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¶
struct scsi_device * sdev
SCSI device for which BIOS geometry is to be
determined
struct block_device * bdev
block device associated with sdev
sector_t capacity
capacity of SCSI device
int 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.
