SYSTEM BIOS
8.4.1 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:
NOTE: For all systems, BIOS ROM Family = 786F1, PnP ID = CPQ0968, and Subsystem vendor ID = 103Ch.
The ROM family and version numbers can be verified with the Setup utility or the System Insight
Manager or Diagnostics applications.
8.4.2 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.
8.4.3 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
