As shown in the following figure, support with an AOL-compliant NIC PCI card (such as the Intel
PRO/100+ Management Adapter Solution) requires no auxiliary cable since the communication of
alert events is handled through the PCI bus interface.

Figure 5-13. AOL Implementation (Generic Representation)
The 82801 ICH initiates event notification by transmitting an alert message over the SMBus-type
Alert Clock/Alert Data interface to a NIC card. On these systems the Alert Clock/Alert Data
signals are wired-Or'd with the SMBus signals and use the SDONEn/SBOn signals lines for
routing to a NIC card on the PCI bus.
The ICH's alert message will be the result of a signal from a sensor (thermal or CPU state) or from
the ICH's detection of the system's running status. Upon receiving the alert message from the ICH
the NIC transmits the appropriate, pre-constructed message over the network.
The AOL implementation requirements are as follows:
1. Intel PRO/100 VM Network Connection drivers 3.80 or later (available from Compaq).
2. Intel Alert-On-LAN Utilities, version 2.5 (available from Compaq).
3. Management console running one of the following:
a. HP OpenView Network Node Manager 6.x
b. Intel LANDesk Client Manager
c. Sample Application Console from the Intel AOL Utilities (item #2 above)
