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.
