4.6 Other Headers, Slots and Sockets
4.6.1 H8 Programming Headers
The microcontroller firmware for system management/keyboard/mouse control can be
upgraded in two ways. The user can either use a special DOS* utility known as
KSCFlash (in-circuit) or use an external computer connected (remote) to the system
via the serial port on the development board. KSCFlash is available on request from
your Intel representative.
If the user chooses to use an external computer connected to the system via the serial
port, there are four jumpers that must be set correctly first. Please refer to Table 15
for a summary of these jumpers and refer to Figure 7
for the location of each jumper.
Required Hardware: one Null Modem Cable and a Host Unit with a serial COM port
(System used to flash the development board)
Here is the sequence of events necessary to program the H8 via the serial port.
1. Extract all files (keep them in the same folder) to a single directory of your
choice on the host machine or on a floppy disk.
2. Connect a NULL modem cable to the serial ports of each platform (host and
unit to be flashed).
3. With the development board powered off, move the following jumpers to the
programming stuffing option.
a. J9G2 (remove) (default: 1-2), Sets SMC_INIT_CLK high.
b. J8B1 (2-3) (default: 1-2), link the Host Unit to on-board H8.
c. J8B2 (2-3) (default: 1-2), link the Host Unit to on-board H8.
