Configuring the Boot Environment
HP-UX version 11.00.03 Starting and Stopping the System 3-13
Table 3-5 describes the environment variables you can define for the primary
bootloader. See the conf(4) man page for more information.
-a [C|R|S|D] devicefile Accept a new location as specified by
devicefile and pass it to the loaded
image. If that image is a kernel, the kernel
erases its current I/O configuration and
uses the specified devicefile. If the C, R,
S, or D option is specified, the kernel
configures the devicefile as the console,
root, swap, or dump device, respectively.
The -a option can be repeated multiple
times. For a description of the devicefile
syntax, see “Modifying CONF Variables.”
-f number Pass the number as the flags word.
-i string Set the initial run-level for init (see the
init(1M) man page) when booting the
system. The run-level specified will
override any run-level specified in an
initdefault entry in /etc/inittab
(see the inittab(4) man page).
Table 3-5. Boot Environment Variables
Parameter Meaning
btflags Specifies the number to be passed in the flags word to the
loaded image. The default is 0.
consdev Specifies the console device for the system. The consdev
parameter has the form (v/w/x.y.z;n) where
v/w/x.y.z specifies the hardware path to the console
device and n is the minor number that controls
manager-dependent functions (n is always 0). The default
is (15/2/0;0).
