Initially, I would have suspected that the CPQASM.SYS driver was not loading, corrupt, or actually the wrong driver for the originalhardware. Introducing replacement hardware may have complicated the problem.
When selecting motherboards and firmware we must take into account that only one of the three Compaq drivers listed below is typically installed on a server. The type of management controller used in the server determines which driver is applied. Here's where changing the motherboard and firmaware may have complicated the problem if the driver was not properly updated.
Assuming the replacement hardware is indeed Compaq compatible, the Compaq Drivers invloved are:
Compaq Integrated System Management Controller driver, CPQCSM.SYS
Compaq System Management Controller driver, CPQSS.SYS
Compaq Advanced System Management Controller driver, CPQASM.SYS
These drivers may fail to load in the following cases:
The system firmware does not support Microsoft Windows 2000.
The server boot drive was built on another system and was then installed in the server.
The servers boot drive was restored from a backup copy, such as a tape backup.
When the driver fails to load, even Compaq Insight Manager will not be able to display or set any data related to this problem. To work around this issue, consider upgrading to the latest system ROM (tosupport Microsoft Windows 2000) and reinstall the system management component. This is required in order for the drivers to load properly and re-enable system management support.
