Cache Jumper
This jumper (J6) selects either synchronous or asynchronous cache type. If
the PC is not installed with any level-2 cache, the default jumper setting is
synchronous cache. The following illustration shows the two cache-type
jumper settings.
Space-Bar Power-On Feature Jumper
The Space-Bar Power-On feature (JP4 “KBD Start” on the system board)
enables you to turn on the PC using the spacebar. To disable this feature, set
the Space-Bar Power-On field in the Setup program to Disable, or remove
the jumper. Removing the jumper overrides the setting in the Setup
program.
NOTE: To use the Power-On spacebar feature, an HP Vectra Keyboard displaying a
Power-On icon is required.
