ECC Memory
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects
single-bit errors. When ECC memory is installed, the BIOS supports both ECC and
non-ECC mode. ECC mode is enabled in the Setup utility (see “Setup Utility” in Section 2).
The BIOS automatically detects if ECC memory is installed and provides the Setup option
for selecting ECC mode.

Hardware Monitor
The National Semiconductor Heceta LM79 chip provides economical instrumentation
capabilities for reduced cost of PC ownership when the system is used with the LANDesk
®
Client Manager. This single-chip ASIC features:
integrated ambient temperature sensor
power supply voltage monitoring to detect excessively high or low voltage levels
registers for storing POST hardware test results and error codes
remote reset capabilities from a remote peer or server through LANDesk Client
Manager
