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.
The man pages for
prtconf
(1M),
system
(4) and
driver.conf
(4) include
additional details. For example:
