Serial Console (Remote Access)

The XTX 820 supports the serial console (or console redirection) feature as Remote Access in the BIOS Setup Utility. This I/O function can be accessed by an ANSI-compatible serial terminal, or the equivalent terminal emulation software running on another system. This can be very useful when setting up the BIOS on a production line for systems that are not connected to a keyboard and display.

Serial Console Setup

The serial console feature is implemented by connecting a standard null modem cable between one of the serial ports, such as Serial 1 (COM1) or Serial 2 (COM2), and the serial terminal or a PC with communications software. The BIOS Setup Utility controls the serial console settings for the XTX 820. Refer to Chapter 4, BIOS Setup Utility for the Remote Access (serial console) settings, and the settings for the serial terminal, or PC with communications software. A brief connection procedure is also provided in Chapter 4, under Accessing BIOS Setup Utility (Remote Access).

Temperature Monitoring

Pentium/Celeron M processors make use of the thermal monitor feature to help control the processor temperature. The maximum junction operating temperature for Pentium/Celeron M processors is 100°C. The integrated TCC (Thermal Control Circuit) activates if the processor die reaches its maximum operating temperature. The activation temperature used by the Intel Thermal Monitor activates the TCC, but cannot be configured by the user nor is it software visible.

The Thermal Monitor can control the processor temperature through the use of two different methods defined as TM1 and TM2. The TM1 method modulates (starts and stops) the processor clock at a 50% duty cycle. The TM2 method initiates an Enhanced Intel Speedstep transition to the lowest performance state once the processor silicon reaches the maximum operating temperature and is only supported by Intel Pentium M processors. The TM2 mode should only be used for Intel Pentium M processors and is not supported by Intel Celeron M processors.

The Thermal Monitor supports two modes (Automatic and On-Demand) to activate the TCC. The Intel Thermal Monitor Automatic Mode must be enabled through a setup node in the BIOS. No additional hardware, software, or handling routines are necessary when using Automatic Mode.
