Console Modes and Mode Change Commands

Console Operation

2–3

PIO Mode — Program I/O mode may be entered from either of the other
modes. To enter PIO mode, use one of these commands: SET TERMINAL
PROGRAM or PIO.
In PIO mode, all keyboard characters are passed to the operating
software. For a remote operator to use PIO mode, full access privileges
must be set by the local operator.
CIO Mode — Console I/O mode may be entered from PIO mode by
pressing the Break key. First, be sure the Local Console Disable switch on
the summary panel is released (button out). Then press the Break key on
the console terminal. If the Local Console Disable switch is set (button
in), the Break character is passed to the operating software like any other
character.
CIO mode may be entered from MIO mode by using the CIO command.
To recognize and process CIO mode console commands, the operating
software must be halted and the processor must be running the console
firmware. If you enter a CIO command (except for HALT) with the
operating software running, an error message returns.
CAUTION
To accept the CIO mode console commands, the processor must
be halted. Any attempt to access the system registers while the
system is running may cause the system to crash. All operators
with appropriate privileges may halt, start, or continue the
operating software from CIO mode.
MIO mode — Module I/O mode cannot be entered directly from PIO
mode. MIO mode may be entered only from CIO mode. To enter MIO
mode, use the MIO command.
MIO mode console commands affect only the console; the processor may
be running or halted. For a remote operator to use MIO mode, full access
privileges must be set by the local operator.

Function

BOOT:
>>> BOOT /R5:4 DIA7

General register R5 passes a value of 4 (hex) to the
virtual memory bootstrap (VMB) program, setting
bit <02>. Then the boot takes place from disk drive
unit 7.

>>> BOOT DIA0, DIB1, DIF0, DIG1
Four device specifiers are used, separated by
commas. The system selects one or more of the
paths to one or more of the boot devices. (See
Section 2.6.)
>>> BOOT MAIN

The boot takes place from the stored boot command
location called MAIN.

>>> BOOT

Without arguments, the boot takes place from the
stored boot command location called DEFAULT.

SET BOOT:
>>> SET /P BOOT MAIN /R5:4 DIA5
Opens a stored boot command location called MAIN
and stores the command both in volatile memory
and in EEPROM. (If the SET BOOT had been
issued without the /P qualifier, the command would
be stored in volatile memory only.)
>>> SET /P BOOT DEFAULT /R5:4 DIA7
Opens a stored boot command location called
DEFAULT and stores the command both in volatile
memory and in EEPROM.
>>> SET /P BOOT MAIN

Without arguments, the command clears the
location called MAIN.

Figure 2–4 shows how the device specifiers select a system cabinet
drive or Ethernet port in an entry-level system. (The summary panel
controls the system cabinet drives as shown in Figure 1–3.) The drive
unit numbers correspond to DSSI bus addresses that are hardwired on
the drive backplanes. The left drive slot contains unit 5, and the right
drive slot contains unit 7. DSSI bus address 6 is used by the primary I/O
module in slot 2 of the logic backplanes. DSSI bus address 7 is used by
the secondary I/O module in slot 1.
Figure 2–5 shows how the device specifiers select an expander cabinet
drive in an expanded, dual access system. (The summary panel controls
the expander cabinet drives as shown in Figure 1–4.) The drive unit
numbers correspond to DSSI bus addresses that are hardwired on the
drive backplanes. Units 0 through 4 are always carrier drives. Unit 5
may contain either a cannister drive or a carrier drive as an option. An
expander cabinet does not support drives in both unit 5 slots. There are
no system cabinet drives in an expanded, dual access system.
