I am having problems using 2 IBM m1015 cards which I have succesfully flashed with P15 IT-firmware when inserted in my new ASrock Z77 Extreme4-m motherboard.
I am only able to get 1 card at a time working in the "top" (designated PCIE1 ) PCIe-x16 slot.
If I insert a second card in the other PCIe-x16 (designated PCIE3) slot no connected drives will appear on the second controller
(the ones connected to the first controller card appear anyhow ).
When having both of these PCIe-x16 slots populated they will be running in 2 * PCIe-x8 mode according to the motherboard manual.
I have also tried switching the cards around to make sure that my problems wasn't because of one faulty card.
With just one single card inserted, it has to be placed in the topmost PCIe-x16 slot (designated PCIE1 ).
It kind of seems that any of the cards when inserted into the middle PCIe-x16 slot (designated PCIE3) does not get recognized.
When I flashed the 2 IBM m1015 cards with the P15 IT-firmware I did this in another old PC with non-UEFI motherbord BIOS and everything seemed to go well during the flashing process.
BUT: I flashed both of the cards with the OPTION ROM included. Should I not have done this? Should I have flashed only 1 card with the Option ROM included?
Can I now reflash and "get rid of" the Option ROM simply by using?: sas2flsh -o -f 2118it.binUPDATE:
I am following up on my own post above. After updating the motherboard BIOS to the latest version (1.50) both controller cards presented themselves and the connected drives and all seems to work fine.
