Frequently Asked Questions: VS440FX

• What Pentium(r) Pro processors are supported on the VS440FX?
  The VS440FX motherboard supports Pentium(r) Pro processors with VID at 150, 166, 180 and 200 MHz. Changing the processor requires changes in several jumper settings.
  

• What upgrade components can be installed on the VS440FX?
  The VS440FX will accept processor upgrades, various combinations of system memory and the battery/real time clock can be replaced.
  

• How should the switches and jumpers be set on my motherboard?
  On-board switches and jumpers control the configuration options and other features of the motherboard. Check the jumpers document for the VS440FX.
  

• Why does my external speaker not work?
  The speaker connector does not support the common four-pin speaker connection. Please refer to the VS440FX ATX Motherboard Technical Product Specification and order the VS440FX Motherboard Specification Update from the Intel Literature department.
  

• Why does my VS440FX not power-up?
  The VS440FX requires 3.3 volts from the power supply. Additionally, there are some specific requirements for the power sequencing and limits. A momentary switch should be used for the for the power on/off switch and the sleep/resume switch.
  Please refer to the VS440FX ATX Motherboard Technical Product Specification and order the VS440FX Motherboard Specification Update from Intel Literature for more details.
  

• Why doesn't my CD-ROM or second IDE hard drive work with Windows* 95?
  There are two known issues involving CD-ROM or secondary hard drives:
  • The retail version of Microsoft Windows 95 may not recognize the Intel 82371SB PIIX3 IDE controller used on Intel motherboards, causing the BIOS to disable the secondary IDE channel. This can result in IDE devices (such as CD-ROM drives) not being detected or disappearing after the system is rebooted. A utility is available to update the MSHDC.INF file and resolve the issue.
  • Windows 95 also may fail to recognize a CD-ROM drive that does not comply with the ATAPI specification. A technical advisory covers this issue for Intel motherboards using the 82371SB PIIX3 IDE controller.
    

• What is the difference between ECC and parity memory on the VS440FX?
  The VS440FX can use either 36-bit ECC or parity SIMMs. Older 40-bit ECC memory cannot be used due to different pin connections. Since the memory is organized in 64-bit wide path, the eight bits normally used for parity lines can be used for single bit correction, double bit detection ECC or parity error detection. When using parity SIMMs, the BIOS setup utility offers the error detection options of Disabled (no error detection), parity or ECC.
  The VS440FX user installable upgrades document lists 36-bit EDO ECC and parity FPM SIMMs that have been tested.

• How can the onboard audio, USB or hardware monitor be disabled?
  The onboard audio, USB or hardware monitor can be disabled using the BIOS Setup Utility. Select the Advanced menu, then the Peripherial Configuration screen. The menu will offer options to enable or disable the audio, USB or hardware monitor features, if they are present on the motherboard. Other Setup options may be found in the VS440FX Technical Product Specification.
