X10SRi-F - cannot boot / enter bios

[nitromaroder]

Dear colleagues,

I've bought a Supermicro X10SRi-F motherboard and having issues to enter the BIOS (or boot from any devices) - no matter what, the board freezes on "DXE--OOB Data Sync-Up / B2", ignoring "DEL" or "F11" keys. I've already upgraded the BIOS via IPMI to the latest version, with no luck. The current boot freezes on following state:

• DXE--OOB Data Sync-Up / B2

I've understood from AMI BIOS docs that it is related to "Legacy Option ROM Initialization" - but I am unsure, what to do next

My current setup looks like following:

• E5-2630V4
• 128 GB DDR4 (8x 16GB 2133 DDR4 Supermicro)
• No attached devices / add-on cards

Has anyone an hint for me? I would like to understand if this is a board, CPU or RAM issue (unfortunately no other board for testing is available)

Best regards!
