    Motherboard jumper settings There are only a few jumpers on the motherboard that you may need to alter. All others are set at the factory and should not be changed. On the motherboard, pin 1 of each jumper block is indicated by a small triangular marking.

    BIOS upgrade and recovery (PL11, PL3) These jumpers should not normally be changed except by a service engineer or at the direction of a service engineer. CMOS is cleared by moving the PL11 jumper to the 2-3 position for a few moments while the system is turned off, then returning it to the normal 1-2 position.

    Adding more memory You can give your PC more memory by adding or replacing memory modules called “DIMMs”. The motherboard’s two DIMM sockets accept DIMMs of up to 128 Mbytes in any combination (giving a maximum memory capacity of 256 Mbytes). IMPORTANT The DIMMs you use must have the following specification: gold contacts, 3.3V, 64-bit, unbuffered, either SDRAM-type with Serial...

    Adding more video memory Video memory is memory reserved for use by the on-board video controller. More video memory can provide more colours or higher resolutions to an extent determined by the capabilities of your monitor. If your computer has 1 Mbyte of video memory, you can upgrade it to the maximum of 2 Mbytes.

    BIOS SETUP & POST BIOS (pronounced “bye-oss”) stands for ‘basic input/output system’. The BIOS mediates between the computer’s hardware – the processor, memory, and so on – and its software – the operating system and your programs. The BIOS program is kept in permanent, read-only memory or ROM (although if necessary it can be upgraded by an authorised maintainer).

    Terminal POST errors and beep codes There are several POST routines that shut down the computer if they fail. If possible, the BIOS displays a two-digit hexadecimal code and/or sounds a sequence of beeps to identify the point at which POST failed. The most usual errors are listed below. The BIOS also issues one long tone followed by two short tones if the video system is faulty or if an external ROM module (including video ROM) fails.
