The hardware path in a devicefile specification is a string of numbers, each suffixed by slash, (

the HP 27111 bus address.
The minor number, n, in a devicefile specification controls driver-dependent functionality. (See the manual,
Configuring HP-UX for Peripherals, for minor-number bit assignments of specific drivers).
File names are standard HP-UX path names. No preceding slash (

Operation
The

optional devicefile. It then transfers control to the loaded image.
Any missing components in a specified devicefile are supplied with a default. For example, a devicefile of
