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 v.3.0
When ranges for temperature or voltage are exceeded, an interrupt is activated. The
hardware monitor component connects to the ISA bus as a 8-bit I/O mapped device.
Interrupt Controller
The interrupt controller operates as an interrupt manager for the entire system environment.
The controller:
accepts requests from peripherals
issues interrupt requests to the processor
resolves interrupt priorities
provides vectors for the processor to determine which interrupt routine to
execute.
The interrupt controller has priority assignment modes that can be reconfigured at any time
during system operations.
