5. Firmware Update

    

[PROM8908D/E, PROM980x]

    The PROM8908D/E has a firmware PROM located at the back side
of the main board. It can be easily accessed by simply remove the four
plastic stands at the bottom of the machine. The user has to download
the updated firmware image file from the web and copy it into a 27C512
equalivent PROM(with access time 70ns) and replace it. 

    

[PROM8908F]

    The PROM8908F use an embedded flash ROM with the ISP feature.
The user can run the utility program AVR.EXE(with the avr.ini file) on
the PC and using the ISP cable to update the firmware through a PC
printer port.

    After the AVR window was bring up, the printer port was set to
"AUTO" and the CPU type was set to "ATMega128" as the default. No
"FUSE" or "LOCK" bits update was required(leave those four small tick
boxs blank). The user only have to select the correct file(p8908f.bin)
and "PROG" it. All setting parameters will be saved in avr.ini after
program EXIT for the next time re-use.
