Chassis Intrusion
Chassis intrusion is detected via the Winbond W83782D C_OPEN pin.
There is an SDR (sensor data record) for the chassis intrusion event.
If the hardware indicates an intrusion, the HMC clears the hardware
latch in the Winbond, logs the event in the System Event Log (SEL),
which is non-volatile storage, and sets the state of the NBA token for
chassis intrusion based on the current chassis intrusion status.
The BIOS queries the NBA token to determine if it should display a
chassis intrusion message. It then clears the chassis intrusion status in
the NBA token.
Applications such as TopTools query for a chassis intrusion event by
searching the SEL.
Pre-boot Device Test
The HMC detects presence of processors. The BIOS detects presence of
memory and memory errors. If it is a condition that prevents the BIOS
from completing POST, it notifies the HMC so that the HMC can display
error LEDs on the front panel
.
PCI/AGP Power
The BIOS detects presence and power consumption of PCI/AGP devices
plugged in the system. It then passes this information on to the HMC, to
detect overpower situations and to know whether it's possible to turn off
the PCI fan to make the system quieter.
