Config (Emergency) Mode

A feature in the Boot ROM called Conﬁg Mode or Emergency Mode is invoked by holding

the Rst/Abt switch in the `Abt’ (abort) position when the power is turned on. There is no

EEPROM storage associated with this mode. The purpose of this feature is to allow a user

to recover from inconsistencies between attribute values of the current mode governing

console selection and the actual, currently available hardware.

For example, the system is conﬁgured to use the USER MODE values and those values

specify that only RS-232 port A is to be used as a console. The system is now moved to a

location where there is no RS-232 type terminal available but a GRAPHICS monitor and

keyboard are provided. When Conﬁg mode is invoked, by holding down the Rst/Abt

switch during power-on, the Boot ROM will behave as if the Interactive Console Search

control ﬂag is set to YES.

This means the system will not attempt to boot but will ask you to interact with it and des-

ignate the preferred Console Path by answering two prompts. The text of the ﬁrst prompt

is “Press 1 to select this console” this prompt will change in size reﬂecting changes in res-

olution; when the text of the prompt is clear and the size is what you want, press 1. Imme-

diately the second prompt will appear. It’s text is “Press ESC to conﬁrm” you must press

the

Esc key promptly because there is a short time-out to this prompt. The system now

accepts the monitor and the keyboard you used as belonging to the Console Path and will

correctly use them.

NOTE: If you have more than one keyboard connected, the keyboard where

you typed 1 to select Console automatically becomes the

functioning keyboard. The additional keyboard is ignored and

becomes non-functional.

After the

Esc key has been pressed to conﬁrm Console, the system automatically begins to

boot.

Setting Values in the Mode Configuration Menu

The main part of the Mode Conﬁguration menu allows the user to select which of the ﬁve

sets of attribute values to change. A space labeled “Edited” between the Key number and

the Attributes class name contains a YES if the value of the corresponding attribute has

been changed by accessing the other menus and altering values.
