I've just been on to David at Intel support in the US who I've run through this with and have an open case for this under 8000548728. However, I thought I would post this up on the off chance that someone has come across this error as well and found a workaround. Essentially, I've been happily using the Matrix RAID Controller with another PCIe RAID Controller (Highpoint RocketRAID 2720) for months. However, today I was finally going to resolve the video socket issue I've been having with the RMM3 card and decided to upgrade to the latest version of the BIOS available for the motherboard (release notes available here: http://downloadmirror.intel.com/21517/eng/release.txt). However, following the BIOS update and managing to resolve the RMM issue, I've now been presented with an even worse one as I now cannot get the Matrix RAID card to start. In Windows, it shows a warning in Device Manager stating "The Device cannot start (Code 10)". In the Error Manager tab within the BIOS, I have an error code; 146, severity; Major & Instance; N/A entry. The description here shows "PCI out of resources error".
I've already established with David that the issue is in some way related to the PCI resources available and that there may be a potential conflict between the Matrix RAID Controller and the RocketRAID card. However, what I don't understand is how an updated (and apparently improved??) OPROM can cause such an issue? So far, I've tried the following:
- Disabling the Serial Ports in the Advanced settings to try to free up resources.
- Setting the Memory Mapped I/O above 4GB option to Enabled
- Replacing the card in any other slot than the default (Slot 5, Gen2 x8 Connector)
- Disabling the NIC ROMs for one or both NICs to free up resources
- Resetting and clearing the CMOS (AC power off, battery removal etc.)
- Re-flashing the BIOS from the EFI console
Nothing above has worked. I can basically boot from the SSD attached to the RocketRAID Card and still run the VMs stored on the SSD's in RAID 0, but these are also attached to the RocketRAID card. Any combination removing the card will result in me not being able to access my VMs which isn't really a great option either.
I could really do with some guidance on whether any of the following are possible/may help:
- Reinstalling the operating system using the EFI options within the BIOS (what are the benefits/drawbacks of using an EFI option over BIOS?)
- Manual resource allocation to ensure all controllers are happy and have resources (can this be done via EFI somehow? Another utility?)
Please can someone in the know lend a hand here as I've been in IT for a while, but this has run my ideas pool dry.
Thanks in advance,
