Setting Parameters Using the

hme.conf

File

You can also specify the properties described in the section “Setting Parameters
in the /etc/system File” on page 25 on a per device basis by creating the

hme.conf

file in the

/kernel/drv

directory. The properties set in the

hme.conf

file will override the parameters set in the

/etc/system

file. Use

hme.conf

when you need to set a particular parameter for a device in the

system. The parameters you set are read and write parameters that are listed
in Chapter 3.
