IBM 3301690 Bios, Operating Temperature and Temperature Control, Optional Audio Interface

3301690 CPU Card

2.15 BIOS

The 3301690 CPU Board uses a licensed copy of AMI flash BIOS. The features of the flash BIOS used are listed below:

„SMIBIOS (DMI) compliant

„Console redirection function support

„PXE (Pre-Boot Execution Environment ) support

„USB booting support

2.16Operating Temperature and Temperature Control

The maximum and minimum operating temperatures for the 3301690 CPU Board are listed below.

„Minimum Operating Temperature: 0ºC (32°F)

„Maximum Operating Temperature: 60°C (140°F)

A cooling fan and heat sink must be installed on the CPU. The lower side of the heat sink, which is mounted on the CPU must be smeared with thermal paste. This ensures the proper dissipation of heat generated by the CPU.

Heat sinks are also mounted on the northbridge and southbridge chipsets to ensure that the operating temperature of these chips remain low.

2.17 Optional Audio Interface

The 3301690 CPU board does not come with an onboard CODEC but the Intel ICH6 chipset Audio Codec (AC’97) controller. A connector on the CPU card can be used to connect the ICH6 audio controllers to an external CODEC.

2.18 Power Consumption

Table 2-2shows the power consumption parameters for the 3301690 CPU board when a Pentium 4 processor with a clock speed of 3.4GHz, an L2 cache of 2MB and a FSB 800MHz is running with two 1GB, 533MHz DDR modules.
