boot_osflags
The boot_osflags environment variable passes information to the boot
command. That information is dependent on the operating system to be
booted.
When the operating system is Tru64 UNIX, the syntax is:
set boot_osflags flags_value
The options for flags_value are:
a
Load operating system software from the specified boot device (autoboot). Boot
to multi-user mode.
i
Prompt for the name of a file to load and other options (boot interactively). Boot
to single-user mode.
s
Stop in single-user mode. Boots /vmunix to single-user mode and stops at the #
(root) prompt.
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 if the system crashes.
When the operating system is OpenVMS, the syntax is:
set boot_osflags root_number,boot_flags
root_number Directory number of the system disk on which OpenVMS files are located.
For example:
root_number Root Directory
0 (default) [SYS0.SYSEXE]
1 [SYS1.SYSEXE]
2 [SYS2.SYSEXE]
3 [SYS3.SYSEXE]
boot_flags The hexadecimal value of the bit number or numbers set. To specify
multiple boot flags, add the flag values (logical OR). See Table 11-7.
