Flags
Flag Description
-flags [longword,]
longword Specifies additional information to the
operating system. In OpenVMS AXP,
specifies system root number and boot flags.
In DEC OSF/1 AXP, specifies boot flags.
Refer to Setting Boot Flags (boot_osflags) in
Chapter 4 for a list of possible settings and
their meanings.
The default boot flag setting is null. Use the
set boot_osflags command to change the
default boot flag setting.
-halt Forces the bootstrap operation to halt and
invoke the console program once the image
is loaded and page tables and other data
structures are set up. Console device drivers
are not shut down when this qualifier is
present. Transfer control to the image by
entering the
continue
command.
Examples In the following example, an OpenVMS AXP system boots from
the SCSI disk, dka0. If bootable software cannot be found on
dka0, the system attempts to boot from Ethernet port, eza0.
Boot flag settings are 0 and 1.
>>> boot -flags 0,1 dka0,eza0
In the next example, an DEC OSF/1 AXP system boots from the
SCSI disk, dka0, using boot flag setting i.
>>> boot -flags i dka0
In the next example, the system boots from the SCSI disk, dka0,
but remains in console mode. Subsequently, you can enter the
continue
command to transfer control to the operating system.
>>> boot -halt dka0
In the next example, the system boots from the default boot
device. The console program returns an error message if a
default boot device has not been set.
