The L2 cache is implemented as direct-mapped, write-back cache with a size of 256 KB.

The power switch, display switch, and standby (suspend) button are mounted on the processor board. They are operated by switch actuators mounted on the CPU cover.

The power switch turns system power on and off. When the switch is pushed to turn the power off, the system displays a warning message that all unsaved data will be lost. The shut down process is then completed by pressing Enter.

The display switch turns the display off and initiates a beep if the display is closed with the computer on. When used with the standby switch, the display switch initiates a system restart.

The standby (suspend) button initiates and exits Standby (suspend). As described above, the standby button, when used with the display switch, initiates a system restart. When used with the Fn key, the standby button initiates Hibernation.

The processor board contains 8 MB or 16 MB of onboard memory and can be expanded to 72 or 80 MB by adding a 64 MB memory expansion board. The memory expansion boards are available in 8, 16, 32, and 64 MB DRAM configurations. Each module is composed of two boards assembled together. The system ROM is shadowed in system memory.

The infrared subsystem (IrDA) provides two-way wireless communication using infrared as a transmission medium. Proper operation requires the communicating infrared ports to be within a 30-degree path and no more than three feet (1 meter) apart.

The processor board must be configured according to the display type. This is done by setting Jumpers JP2, JP3, and JP4 on the processor board. Use Table 1-5 to determine proper jumper settings for the display.
