Turn On Computer - HP 9000 200 Series Manual

Turn on Computer
(and Hold Down Spacebar if You Have Other Systems On-Line)
If there are no other on-line systems, you need not hold down the space bar (the boot
ROM searches for your system and loads the default system automatically).
After pressing the computer's power switch on (or rebooting), press the space bar on the
keyboard and hold it down.
Figure 1-1. Turn Computer On and Hold Down the Space Bar
Holding down thE' sparE' bar doE's two things:
• Tells the computer to wait until you are ready to load a system (instead of
automatically loading the first one it finds) .
• Allows you to watch the computer's display as it:
• performs its self-test (checks mf'lllory, ptr.)
• searches for interfaces (such as HP-IB, RS-232C. etc.),
and on-line systems (operating systems stored on discs, tapes, and ROM
cards). For a list of the order in which the devices are search, see the last
section in this chapter, "Order of Devices Searched by the Boot ROM."
