Madburg, thanks for a fantastic guide!
I got a new pulled M1015 from EBay, plugged it in, attempted to flash, swapped mobo's, flashed, reinstalled, viola!
The motherboard in my UNRAID is an Asus P8B WS with the 0805 BIOS, it recognized the card and let me erase it but I got the notorious PAL error when I tried to flash the BIOS. I pulled the card and put it into my desktop machine with an ASUS M4A89GTD PRO/USB3 mobo and it flashed with no issues.
I reinstalled the card in my UNRAID machine, upgraded to 5.0B11 and it's doing a parity check at about 120MB/SEC.
SBR attached and again, thanks for the outstanding work!
