NAME

obp_helper- download OpenBoot to system memory

SYNOPSIS

obp_helper [-eivqr] [-oFilename] [-dFilename] [-mboot_proc] [-A {on| off}] [-D {on| off}] [boot-arguments]

DESCRIPTION

---

Note -

obp_helper is normally executed by the bringup(1M) script, not on the command line. You may execute it on the command line only as obp_helper -e or, under certain conditions, obp_helper -r.

---

obp_helper provides an environment in which OpenBoot can run. It then downloads OpenBoot and provides time-of-day and EEPROM simulation services to it.

obp_helper executes until OpenBoot exits or a bringup(1M) is executed.

obp_helper behaves like a daemon; it spawns a copy of itself and the parent process exits, effectively disconnecting itself from the controlling terminal.

OPTIONS

The following options are supported:

-e

Display the current settings of EEPROM options alterable by obp_helper.

-i

Invalidate the boot arguments in EEPROM.

-v

Execute in verbose mode.

-q

Execute in quiet mode.

-r

Restart obp_helper. Execute obp_helper -r only if OpenBoot is already executing on the system, but obp_helper has died or otherwise disappeared.

-o filename

Download the specified file instead of the standard OpenBoot executable.

-d filename

Download the specified file, not the standard download_helper executable.

-m boot_proc

Make the processor selected by boot_proc the boot processor.

-A [on | off]

Enable (on) or disable (off) OpenBoot auto-boot mode. The -A option has the same effect as a setenv auto-boot? [true | false] command to OpenBoot; it alters the state of the auto-boot? flag in the OpenBoot simulated EEPROM. When auto-boot is enabled, the bringup(1M) command brings up the system completely, using the appropriate boot disk as determined by other OBP variables. When auto-boot is disabled, bringup(1M) completes in such a manner that the OBP prompt (OK) is displayed on the netcon(1M) Window.

-D [on | off]

Enable (on) or disable (off) OpenBoot diagnostic mode. This option has the same effect as the setenv diag-switch? [true | false] command to OpenBoot; it alters the state of the diag-switch? flag in the OpenBoot simulated EEPROM.

boot-arguments

Pass boot arguments verbatim to the OpenBoot boot command. You can specify standard OpenBoot device aliases such as disk and net. These arguments affect the current boot only; subsequent boot commands use the standard OpenBoot boot-device and boot-file arguments.

ENVIRONMENT VARIABLES

The environment variable SUNW_HOSTNAME must be set to the name of the domain.
