I had the same problem using EUFI bios. It would say it the card would enter configuration after initialization then go to the bios on my NICs, back to the system bios and then boot. I CTRL+C'd for the card, then F8'd to configure bios and it opened the card configuration before it opened the bios. Worked for me, YMMV.

RockDog, mine had the same sticker. Right or wrong I used the instructions for the M1015 and SAS2008 chipset. Worked like a champ! I used the P10 download.

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! IBM_M1015.zip
