Parameter Options

You can set the hme device driver parameters in three ways (ndd, /etc/system, and hme.conf), depending on your needs. To set parameters that are valid until you reboot the system, use the ndd utility. Using ndd is a good way to test parameter settings.

To set parameters so they remain in effect after you reboot the system:

• Add the parameter values to /etc/system when you want to configure parameters for all devices in the system.

• Create the hme.conf file and add parameter values to hme.conf when you need to set a particular parameter for a device in the system.

If you want to test parameter settings, use the ndd utility described in Chapter 3. With ndd, the parameters are effective until you reboot the system. To make the parameter settings permanent, enter the values in /etc/system or hme.conf as described in this chapter.
