Compaq Server Management Driver
The Compaq Server Management Driver resets the ASR timer continually. The timer is set to
expire in 10 minutes. If the ASR timer counts down to zero before being reset, due to an
operating system crash or a server lockup, ASR restarts the server.
The Server Management Driver is independent of the ASR timer. You should load it and enable
the ASR timer. This step allows the driver to detect and log information in the IML regarding
numerous hardware and software errors. However, you cannot enable the ASR timer without
loading the Compaq Server Management Driver. The Server Management Driver provides
many benefits in addition to ASR, including ECC error detection, CPU processor memory, and
hard drive pre-failure support. Also, the Server Management Driver works with Compaq Insight
Manager to provide a complete systems management solution.
The following ASR flowchart shows you the sequence of events after a hardware or software
error occurs:

ASR Security
The standard Compaq password features function differently during ASR than during a typical
system startup. During ASR, the system does not prompt for the power-on password. This
action allows ASR to restart the operating system without user intervention.
