4.5.3 System Status
These systems provide a visual indication of system boot and ROM flash status through the
keyboard LEDs and operational status using bi-colored power and hard drive activity LEDs as
indicated in Tables 4-13 and 4-14 respectively.
✎
The LED indications listed in Table 4-13 are valid only for PS/2-type keyboards. A USB
keyboard will not provide LED status for the listed events, although audible (beep) indications
will occur.
