Boot Command - Compaq DS10L - AlphaServer - 256 MB RAM Reference Manual

2.18.3 boot_osflags
The boot_osflags environment variable passes information to the
boot command. That information is dependent on the operating
system to be booted.
Syntax for Tru64 UNIX:
where flags_value can be:
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.
Syntax for OpenVMS: set boot_osflags root_number, boot_flags
Where root_number is the directory number of the system disk on which
OpenVMS files are located. For example:
root_number
0 (default)
1
2
3
And boot_flags are the hexadecimal value of the bit number or numbers set. To
specify multiple boot flags, add the flag values (logical OR). See Table 2–8.
