4.6.1H8 Programming Headers

The microcontroller for system management/keyboard/mouse control can be upgraded in two ways. The user can either use a special MS-DOS* utility or use an external computer connected to the system via the serial port on the board.

If the user chooses to use an external computer connected to the system via the serial port, there are five jumpers that have to be set correctly first. Please refer to Table 11 for a summary of these jumpers and refer to Figure 4 for the location of each jumper.

Caution: Make sure the motherboard is not powered on and the power supply is disconnected before moving any of the jumpers.

Here is the sequence of events necessary to program the H8.

1.With the board powered off, move the five jumpers listed in Table 11 to the programming stuffing option.

2.Power the S5 voltage rails by attaching an AC brick or an ATX power supply to the system.
