Figure 4-3. Example Display Listing Operating Systems
If you know that a particular choice is desired (such as
"lH"),
then you can type that response
as the SPU powers up to make a selection. This simple human interface makes it possible to
rnake a selection without even having or seeing a monitor. Note that only keys
A-Z,
a-z, and
0.-9 are allowed to select a system. Other keys are simply ignored.
Because it is possible to find more systems than there are lines on the display, the search scan
can be paused and continued by toggling the RETURN key. The line next to the bottom of the
screen indicates the current state with one of two messages:
SEARCHING FOR A SYSTEM (RETURN To Pause), or
PAUSED (RETURN To Continue)
The menu will wrap around to the top of the screen and overwrite itself whenever all available
lines are used. ""'hen the Boot ROM is paused, all activity stops. Because the keyboard is
polled, there may be a delay before a key press takes effect.
