- int ata_std_bios_param(struct scsi_device * sdev, struct block_device * bdev, sector_t capacity, int geom);
- SCSI device for which BIOS geometry is to be determined
- block device associated with sdev
- capacity of SCSI device
- location to which geometry will be output
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.
Defined by the SCSI layer. We don't really care.
