2.8.1 BOOT
BOOT initializes the system, loads a program image from a specified boot device,
and transfers control to that program image.
When you do not supply a boot-spec, the default boot device is used. When you do
not supply flag(s), a value of 0 is assumed.
The console program accepts a terminating colon on the boot-spec, but ignores the
colon when the name is processed.
The BOOT syntax is:
BOOT[/OVER][[/R5:]<flag(s)> boot-spec]
The boot-spec format may be dduuu/PATH=path-list . . . dduuu/PATH=path-list,
where:
dd is a device mnemonic.
uuu is a unit number (0 to 999).
/PATH=path-list is a qualifier. See Table 2–5.
Or, the boot-spec format may be a variable that specifies the boot devices and
paths. See Section 2.8.13.1.
Table 2–5 describes the qualifiers. Table 2–6 lists the VMB program /R5:<flag>
values.

Function
Passes parameters to the virtual memory bootstrap (VMB)
program. See Table 2–6.
Specifies a path to a boot device. The path-list specifies zones
and slot numbers in the path. When the path-list has more
than one slot, you separate the slots by commas. The path-list
format is zss, where:
z is a zone ID (A or B).
ss is a slot number (10 to 17, 20 to 27) of an adapter
connecting to a boot device.
Overrides the results of the bootability test to allow a Simplex
mode boot.
