I believe there's a jumper or a dip switch that has to be set correctly to allow the eeprom to be written. The instructions are in the service manual.?

All:
I posted about this over at the EEVBLOG, but I figured I should post it here too. I am having a problem loading the Harmonic and Time Domain Options (OPT2 & OPT10) for my HP-8753E. I have a License Key for my VNA¡¯s serial number, and the instrument posts the matching serial number as to what is printed on the instrument¡¯s physical label on the back.
When I follow the installation process I keep getting the ¡°OPT COR FAIL¡±. Some of the helpful folks on the EEVBLOG suggest that I may have to remove the EEPROM and force those bits in order to activate. While I am willing to do this, it does pose a degree of risk of corrupting my only EEPROM, not to mention I would have to invest in a Reader/Writer with that would accept this EEPROM package.
Before I take on this risk, I want to make sure there is nothing further I should try.
