Hello Andrew I can only think of three possible reasons this error would occur: If you have a known good h700 integrated to test with then you can find out if the slot or controller card are the issue. If you encounter the same problem with a known good controller then be sure to remove/disconnect all PCI and USB devices. If the issue still occurs with a known good controller and all PCI/USB devices removed then it would appear to be a slot issue and require a replacement system board. If a known good controller resolves the issue then the problem is with the controller. If the issue is resolved by disconnecting/removing PCI/USB devices then you should troubleshoot to locate the problem component. Find out if the component is faulty or exceeding the power limitations of the system. Thanks
I've got a T610 that has failed to boot.  Error message is Firmware Failed Validation Adapter needs to be reflashed.  The RAID card is p/n or374m which apparently is the PERC H700. Downloading the firmware update files, dropping them on a bootable flash drive, and booting, the update util hangs at "Searching for the PERC H700 Integrated." Help please?
