Any way to upgrade firmware on these cards? im only able to run 2.50.16. I have a chip programmer but not found much info on this

if you found any upgrade past 2.5.16 let me know also i have 3.2 and 3.3 and .33.4 and 3.5 but they dont see my card once installed

I believe we are just screwed. No way to upgrade the chip as far as i know even though i have a chip programmer
