1-12 Technical Information
Memory upgrades are easy with DIMMs. Advantages of using DIMMs are listed below:
DIMMs do not need to be installed in pairs on the system board.
DIMMs of different memory types and sizes can be installed on the same board.
No switches or jumpers need to be set if the memory is changed.
The system BIOS automatically detects the DIMMs.
See “Checking the Memory in the System” in Section 3 for the valid DIMM configurations.
Hardware Monitor
The National Semiconductor Heceta LM78 chip provides economical instrumentation
capabilities (NEC MagicEye™ Technology) 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, fan speed, 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.
The interrupt levels are described in Table 1-6. Interrupt level assignments 0 through 15 are
in order of decreasing priority. See Section 2 for information on using the Setup utility to
change the interrupts.
