The driver uses the settings from the EEPROM set in the SCSI BIOS
The driver uses the settings from the EEPROM set in the SCSI BIOS
setup. If there is no EEPROM, the driver uses default values.
Both can be overridden by command line parameters (module or kernel
parameters).
The following parameters are available:
- safe

Default: 0, Acceptable values: 0 or 1

This driver works, but is still in experimental status. So better
have a bootable disk and a backup in case of emergency.

To compile this driver as a module, choose M here: the
module will be called dc395x.
