I not really sure what do you mean by "device password".
However, for more details about EP910LI-35 and MAX+PLUS® II software, you may refer to the following link:
Thanks for your reply.
in programmer tool from MAX+PLUS® II for each typeof FPGA, you need a code/password to allow working with it (EP910LI-35, EP610LI-35, ...). If not, is says device is not enabled and can't program anything.
I do not have these codes anymore, 15 years elapsed since last time we used it.
This is an old setup/programming environment (Pentium 133, VESA interface card with programmer) and unsure dongle/license will work with lastest MAX+PLUS® II software fresh install. This is the reason why I am looking for this code.
