Chapter 1: Introduction Chassis Intrusion Detection The chassis intrusion circuitry can detect unauthorized intrusion to the system. The chassis intrusion connector is located on JL1. Attach a micro-switch to JL1. When the micro-switch is closed, it means that the chassis has been opened. The circuitry will then alert the user with a warning message when the system is turned on.

Chapter 1: Introduction ACPI/PC 98 Features ACPI stands for Advanced Configuration and Power Interface. The ACPI speci- fication defines a flexible and abstract hardware interface that provides a stan- dard way to integrate power management features throughout a PC system, including hardware, operating system and application software.
It is even more important for Pentium II processors that have high CPU clock rates of 300 MHz and above. SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA/P6SBM accommodates ATX power supplies. Although most power supplies generally meet the specifi- cations required by the CPU, some are inadequate.
AIC -7895 MultiChannel Single-Chip UltraSCSI SUPER P6DBS/P6SBS has an on-board SCSI controller which is 100% compat- ible with all major operating and hardware platforms. PCI 2.1 and SCAM Level 1 compliance are assured. Two independent UltraSCSI channels provide a per channel data transfer rate of 40 MB/s.

Chapter 3: Troubleshooting Chapter 3 Troubleshooting Troubleshooting Procedures Use the following procedures and flowchart to troubleshoot your system. If you have followed all of the procedures below and still need assistance, refer to the ‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.
Manual SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA No Power Make sure the default jumper is on and the CPU is correctly set up. Turn power switch on and off to test system. If power is still not on, turn off system power to move jumper setting on JP20 from 2-3 to 1-2.
Chapter 3: Troubleshooting Losing the System’s Setup Configuration Check the jumper JBT1 setting. Ensure that you are using a high quality power supply. A poor quality power supply may cause the system to lose the CMOS setup information. Refer to Chapter 1 of this manual for details.
Manual SUPER P6DBS/P6DBE/P6DBU/P6SBU/P6SBS/P6SBA Frequently Asked Questions Question: What are the differences between the various memories that the 440BX motherboard can support? Answer: The 440BX integrates a main memory DRAM controller that supports a 64-bit or 72-bit (64 bit memory data plus 8 ECC bits.) DRAM from 8 MB to 512 MB for SDRAM and from 8 MB to 1 GB for EDO or registered DIMM.
