- 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
