Memory modules and replacement processors are examples of electrostatic sensitive devices (ESSDs). All work that involves contact with the PH440 NLX Motherboard should be done in an area completely free of static electricity. We recommend using a Special Handling Area (SHA) as defined by EN 100015-1: 1992.

The PIIX4e provides the PCI to ISA bus bridge and contains the system’s RTC, the IDE interfaces, the DMA and Interrupt Controllers. The PIIX4e also provides ACPI support, an SMbus controller and all the general purpose I/O ports used on the PH440 NLX motherboard. The PIIX4e device is packaged in a 324 pin BGA.

Remove any expansion cards that impede access to the video memory upgrade socket (see the motherboard diagram at the start of this chapter). Unpack the upgrade kit. Hold the SODIMM chip by its edges and be careful not to touch the metal pins. MITSUBISHI ELECTRIC MOTHERBOARD DIVISION PAGE 15 OF 51...
Then lift the processor body (2) out of the socket. Caution Handle the processor with care, by the body only. Avoid touching the connector at the bottom. Store in an antistatic container. MITSUBISHI ELECTRIC MOTHERBOARD DIVISION PAGE 16 OF 51...
Warning The processor requires continuous airflow. Return to their original position any expansion cards that had been removed earlier, then refit and secure the system cover. MITSUBISHI ELECTRIC MOTHERBOARD DIVISION PAGE 17 OF 51...

The amount of video memory fitted to the motherboard is automatically detected by the BIOS. Video memory upgrade modules do not require an SPD ROM. 2MB builds are based on 8Mb devices. 4MB builds use 16Mb devices. 4MB modules must be based on 16Mb devices.

The NLX system fan is controlled by the motherboard such that it stops rotating when the system is in ‘Suspend’ mode. As a build option, the PH440 NLX motherboard supports variable fan speed control in which the speed of the fan is raised as the temperature of the processor increases.
