System Id And Rom Type; Temperature Status; Drive Fault Prediction - HP Compaq dc7100 DT Technical Reference Manual

8.5.1 System ID and ROM Type

Diagnostic applications can use the INT 15, AX=E800h BIOS function to identify the type of
system. This function will return the system ID in the BX register. systems have the following
IDs and ROM family types:

8.5.2 Temperature Status

The BIOS includes a function (INT15, AX=E816h) to retrieve the status of a system's interior
temperature. This function allows an application to check whether the temperature situation is at
a Normal, Caution, or Critical condition.

8.5.3 Drive Fault Prediction

The BIOS directly supports Drive Fault Prediction for IDE (ATA)-type hard drives. This feature
is provided through two Client Management BIOS calls. Function INT 15, AX=E817h is used to
retrieve a 512-byte block of drive attribute data while the INT 15, AX=E81Bh is used to retrieve
the drive's warranty threshold data. If data is returned indicating possible failure then the
following message is displayed:
1720-SMART Hard Drive detects imminent failure
