Loading a Driver with driverLoader

driverLoader 를 사용한 드라이버 로드

You can load your driver into an already running system. The driverLoader command loads or configures a driver after startup time. You initiate the command as follows (as superuser):

/usr/etc/driverLoader option [v] [instance]

Specifying v results in more verbose output from driverLoader. The instance argument can be used only with the d option, as described below.

The option is one of the following:

• a
  • Configure all devices. This option is used when driverLoader is run during system boot (by /etc/rc).
• i
  • Interactive mode. With this option, you can look at all active and boot drivers in the system configuration. Note that if you add a driver to the system, the driver isn't recognized as "active" until you reboot.
• d=deviceName
  • Configure one device interactively. This is how you load drivers that aren't specified in the system configuration. This is usually used for testing purposes. You can specify instance to use a specific Instancen.table file. For example, if you specify instance as 1, the driver is probed using the information in its Instance1.table file.

Here's an example of using the d option:

# /usr/etc/driverLoader d=myDriver

Here's an example of using the d option and specifying instance:

# /usr/etc/driverLoader d=fooDriver 1
