NAME
setboot - display and modify boot variables in stable storage
SYNOPSIS
/usr/sbin/setboot
[-p primary-path ][
-h HA_alternate -path ][-a alternate -path ][-b
onoff]
[-s onoff][
-v][-t testname =onoffdefault]... [-T testname
=onoffdefault]...
DESCRIPTION
The
setboot command displays and sets boot variables in stable storage (also known as nonvolatile
memory). Any user can display the values; only a superuser can change them.
On all systems, the variables are: primary path, alternate path, autoboot flag, and autosearch flag. If
SpeedyBoot is installed, the variables expand to include: early CPU tests, late CPU tests, memory initial-
ization (on Itanium(R)-based systems), full memory tests, processor hardware tests (on PA-RISC), plat-
form dependent tests (on Itanium-based systems), IO Hardware tests (on Itanium-based systems), chipset
tests (on Itanium-based systems), and central electronic complex tests (on PA-RISC).
With no options,
setboot displays the current values for the primary and alternate boot paths and the
autoboot and autosearch flags. If SpeedyBoot is installed,
setboot -v also displays the status of
the CPU, memory, hardware, and electronics tests.
SpeedyBoot
The SpeedyBoot firmware and software extensions allows a superuser to control which firmware tests are
executed by the system during the boot process. The tests settings can be specified both for all subse-
quent boots and for the next one only. They are described in the The Tests section below.
The
-v, -t, and -T options of the setboot command provide the user interface to the firmware tests.
Currently -t options is not supported on Itanium-based system architecture.
SpeedyBoot augments the test control that is available on systems that have the Boot Console Handler
(BCH). By turning off some or all of the boot tests, you can shorten boot time appreciably. However, in
the event of a system panic or boot failure, all tests are executed on the subsequent boot.
SpeedyBoot Tests
The SpeedyBoot tests and the possible display values on a PA-RISC platform are summarized in the fol-
lowing table:
