Attributes Description
NV,W Default parameters to be passed to system software during
booting if none are specified by the boot command.
OpenVMS: Additional parameters are the root_number and
boot flags. The default value is NULL.
root_number: Directory number of the system disk on which
OpenVMS files are located.
0 (default)—[SYS0.SYSEXE]
1—[SYS1.SYSEXE]
2—[SYS2.SYSEXE]
3—[SYS3.SYSEXE]
boot_flags: The hexadecimal value of the bit number or
numbers to set. To specify multiple boot flags, add the flag
values (logical OR).
1—Bootstrap conversationally (enables you to modify
SYSGEN parameters in SYSBOOT).
2—Map XDELTA to running system.
4—Stop at initial system breakpoint.
8—Perform a diagnostic bootstrap.
10—Stop at the bootstrap breakpoints.
20—Omit header from secondary bootstrap file.
80—Prompt for the name of the secondary bootstrap file.
100—Halt before secondary bootstrap.
10000—Display debug messages during booting.
20000—Display user messages during booting.
Tru64 UNIX: The following parameters are used with this
operating system:
a—Autoboot. Boots /vmunix from bootdef_dev, goes to multi-
user mode. Use this for a system that should come up
automatically after a power failure.
s—Stop in single-user mode. Boots /vmunix to single-user
mode and stops at the # (root) prompt.
i—Interactive boot. Requests the name of the image to boot
from the specified boot device. Other flags, such as -kdebug (to
enable the kernel debugger), may be entered using this option.
D—Full dump; implies s as well. By default, if Tru64 UNIX
crashes, it completes a partial memory dump. Specifying D
forces a full dump at system crash.
Common settings are a, autoboot, and Da, autoboot and create
full dumps if the system crashes.
