Using IFHW

IFHW is used from a script file, in conjunction with other utilities, to control the deployment. The

IFHW utility enables you to make intelligent queries against the hardware discovery file. Queries

take the form of a logical expression, and the result of the expression is returned as the return code

of the tool, which the hosting script can use to conditionally perform actions.

IFHW command-line syntax

ifhw [drive:][path]hpdiscoveryfilename
