Configure Mode Software Override - HP 340 Series Service Manual

Configure Mode Software Override
Configure nlode is a Boot ROM feature that allows the modification of some power-up defaults
independent of which language will eventually be booted. To enter configure mode press
I CTRL ~
OD
before a system is booted but after the keyboard is initialized (e.g. after the keyboard
Inessage is displayed).
All mass storage operations lock-out and defer the response to the
~
(just as they defer
RESETs). This is to prevent leaving a mass storage device stranded in a strange state (e.g.
disc spinning).

Figure 4-1. Example Power-Up Display in Configure Mode
Once in Configure Mode, two options are displayed. If no key is typed within approximately 5
rninutes, the Boot ROM will time-out and start power-up over again. Regardless of the option
chosen, most of the self-test will be repeated. If the memory test has already been completed
and the extended self-test option is chosen, then the main memory test portion of the self-test
will be repeated, otherwise it will not.
