No, I was just setting up. I have a couple toggle switches working on gpio but that’s it. I was just getting excited I could see it talking through halshow. No servo/spindle drivers yet.
I figured the MPGs should have been the next easiest thing to do

Well, I found a pile of old Dell Optiplex machines for cheap. Im just gonna try a new computer.
I really wish i could have found a way to make the Asus A520M work. Looks like a tough board good for machining environments.
Ill keep everyone posted if the new computer(s) work out :/

Take pictures of both cards and post them here, do not touch the jumpers.
Did you y any chance set them to "setup mode" or something like that? been to long so i am a bit fuzzy....

Again the memory area is disabled, you might try the setpci option
Also, if Linux runs and accesses the card, you may be able to bypass the mesaflash issue with:
sudo mesaflash --recover --device recover --write 5i25_7i77x2.bit
