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.
