An onboard voltage monitor will scan these voltages continuously. Once a voltage
becomes unstable, a warning is raised or an error message is sent to the screen.
Users can adjust the voltage thresholds to define the sensitivity of the voltage
monitor. To adjust the sensitivity, open the BIOS utility and select
Advanced >
Hardware Monitor .
Fan Status Monitor with Firmware/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
3-pin CPU and chassis fans are controlled by the power management functions. The
thermal fan is controlled by the overheat detection logic.
Environmental Temperature Control
The system board has a CPU thermal trip feature. A thermal control sensor monitors
the CPU temperature in real time and will send a signal to shut down the system
whenever the CPU temperature exceeds a certain threshold. This works to protect
the CPU from being damaged by overheating.
Hardware BIOS Virus Protection
The system BIOS is protected by hardware so that no virus can infect the BIOS area.
This feature can prevent viruses from infecting the BIOS area and destroying
valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to 60 A
current and auto-sense voltage IDs ranging from 1.1 V to 1.85 V. This will allow the
regulator to run cooler and make the system more stable.
4.2.2 POST (Power On Self Test)
When you turn on the Color Controller C-80, it performs a series of tests to check the
operation of its components and some of its installed options.
If POST finishes without detecting any problems, a single beep sounds, and the first
screen of the operating system or software program appears.
If POST detects a problem, more than one beep sounds and an error message may
appear on the screen.
Note: A single problem might cause several error messages.
