BOOT
(DUP)
Directs a new monitor to take control of the operating system, or reads into memory
a new copy of the monitor that is currently controlling the system.
Format
BOOT input-spec
Command Options
/FOREIGN
/WAIT
Parameter
input-spec
Specifies the device or monitor file to be bootstrapped. If you omit the input-spec,
RT–11 prompts you with Device or file?.
Description
The BOOT command can perform either of two operations: a boot-block bootstrap
or a monitor-file bootstrap.
• Boot-block bootstrap
The boot-block (hardware) bootstrap operation gives control of the operating
system to the monitor whose bootstrap code is written in the boot blocks of a
volume in a device. You can change the monitor booted by a hardware bootstrap
by issuing the COPY/BOOT command.
To perform a boot-block bootstrap:
1. Make sure the appropriate device handler is present on the volume you want
to bootstrap.
2. Specify only a device in the command line. You can do this by entering the
device’s physical or logical name—if it has been assigned a logical name (see
the ASSIGN command).
The following example bootstraps the XM monitor, RT11XM, whose bootstrap
information is written on the boot blocks of the system device:
.BOOT SY:
RT-11XM V05.6
