Default Re: Creating Multiple Configuration PROM File

All I want to do is change the select bits on the PROM, initiate a
configuration cycle, and have the FPGA loaded with a new/different
configuration. Is this possible? If so, how does one create an .mcs file
with two configurations? Or is it another file extention?

thank you,
rob
