# scsicam\_bios\_param(9)

Determine geometry of a disk in cylinders/heads/sectors.

## NAME

scsicam\_bios\_param - Determine geometry of a disk in cylinders/heads/sectors.

## SYNOPSIS

**int scsicam\_bios\_param(struct block\_device \*** *bdev***, sector\_t** *capacity***, int \*** *ip***);**

## ARGUMENTS

*bdev*

which device

*capacity*

size of the disk in sectors

*ip*

return value: ip\[0\]=heads, ip\[1\]=sectors, ip\[2\]=cylinders

## DESCRIPTION

determine the BIOS mapping/geometry used for a drive in a SCSI-CAM system, storing the results in ip as required by the HDIO\_GETGEO **ioctl**.

## RETURN

\-1 on failure, 0 on success.
