I'm flashing these in a UEFI X99 MSI SLI Plus motherboard. I just flashed a different H310 card in this same motherboard following these same directions about a week ago. I can try to view them in my Supermicro X9SRL-F when I get home, but I would think that if the same type of card worked in the same slot a week ago, it's unlikely that this will fix the issue, but I'm open to suggestions.@rubylaser, are you trying to flash these on a motherboard you have used LSI cards on before? Just checking as I had forgotten about the PCIe problems these have on most Gigabyte and other non-server motherboards and not showing up in BIOS or utilities. Thought I had a couple of failed cards too, but in a SuperMicro board they flashed fine (mine were not from this deal, it was a couple of 9201-16e I think from a Compellant off of ebay.)
