bo -- languardian specific

Syntax

bo [/h] <unit>[,"[<]xx(unit#,partition#)pathname"]

Parameters

<unit>

Specifies the unit number of the device on which the program resides. The unit number can be determined using the prove_scsi command.

xx

xx can be sd for a SCSI device, or fd for a floppy drive, according to the type of device the program is to be loaded from.

unit#

Same the <unit> paramater above.

partition#

The partition in which the bootstrap information resides.

pathname

The name of the program to be loaded, executed or booted.

[<]

Loads the bootstrap and the operating system and returns to the monitor. This allws the setting of breakpoints.

Options

/h

Load only the bootstrap, then returns to the monitor.

Example

To boot an operating system, named my_rtmx from the root partition of the first SCSI drive on the system, type the following command:

bo 0,"sd(0,0)my_rtmx"

To boot RTMX from the first SCSI disk on the system (this is the default setup of the PDE), type the following command:

bo 0

To boot RTMX from the first streaming tape drive on the system type the following command:

bo 1

To boot RTMX from the first floppy drive on the system type the following command:

bo 10

To boot RTMX from the first SCSI disk on the system and allow breakpoints to be set in the operating system, type the following command:

bo 0,"<sd(0,0)rtmx"

Notes

If the /h option is specified, bootstrap is loaded into memory, and then control remains in the PDE instead of booting the rest of the program. Once the bootstrap is loaded into memory and contol is returned to the PDE, all of the PDE commands are available, as well as the following control utilities:

^S -- Execute a single instruction.

^A -- Execute the code pointed to by the program counter.
