SRM Boot Command

boot [-file filename] [-flags longword[,longword]] [-protocols enet_protocol] [-halt] [boot_device]

Description

The boot command performs the following functions:

Initializes the processor.
Loads a program image from the specified boot device.
Transfers control to the loaded image.

Where:

-file filename Specifies the name of a file to load into the system. For booting from Ethernet, this name is limited to 15 characters. Use the set boot_file command to set an environment variable that specifies a default boot file.

-flags longword[,longword] Specifies additional information for the operating system. Use the set boot_osflags command to set an environment variable that specifies a default boot flag values.
OpenVMS boot flags.
Digital UNIX boot flags.

-protocols enet_protocol Specifies an Ethernet protocol(s) that will be used for a network boot. Values may be mop or bootp.

-halt Forces the bootstrap operation to halt and invoke the console program after the image is loaded and the page tables and other data structures are set up.

boot_device Specifies a device path or list of devices that the firmware will attempt to boot. Use the set bootdef_dev command to set an environment variable that specifies a default boot device.

Boot Command Examples

>>>boot	Boots the system from the default boot device.
>>>boot ewa0	Boots the system from Ethernet port ewa0.
>>>boot -file dec2.sys ewa0	Boots the file named dec2.sys from Ethernet port ewa0.
>>>boot -protocol bootp ewa0	Boots using TCP/IP BOOTP protocol from Ethernet post ewa0. (Make sure the environment variables ewa0_protocols and ewa0_inet_init are both set to BOOTP before booting.)
>>>boot -flags 0,1	Boots the system from the default boot device using flag settings 0,1.
>>>boot -halt dka0	Loads the image from disk dka0, but remains in console mode.
>>> boot Trying MOP boot. ... ... ...	Successful boot from a system that is set to secure mode. In this example the boot command is equivalent to:(boot eza0.0.6.0 -file myfile.sys -flags 0)
>>> set boot_file myfile.sys Console is secure >>> >>> boot -file myfile_ev4p2 Console is secure - parameters are not allowed >>> boot -halt Console is secure - parameters are not allowed >>> boot ezb0 Console is secure - parameters are not allowed	Unsuccessful boot examples from a system in secure mode.

-flags longword[,longword]	Specifies additional information for the operating system. Use the set boot_osflags command to set an environment variable that specifies a default boot flag values. OpenVMS boot flags. Digital UNIX boot flags.
-protocols enet_protocol	Specifies an Ethernet protocol(s) that will be used for a network boot. Values may be mop or bootp.
-halt	Forces the bootstrap operation to halt and invoke the console program after the image is loaded and the page tables and other data structures are set up.
boot_device	Specifies a device path or list of devices that the firmware will attempt to boot. Use the set bootdef_dev command to set an environment variable that specifies a default boot device.
