Question
We have 3 SYS-121H-TNR servers (BIOS 2.5) that were built by SMC and we are trying to load Server 2025 on them. All 3 of them have boot issues – when rebooting the machine they launch into an automatic repair (Status 0xC000009Aa) from time to time. They are not customer ready.  Do you have any solution for this issue?

Answer
For SYS-121H0TNR, please go to the motherboard link and check if BIOS 2.7 is available for download or not.  If there is no BIOS 2.7 or newer, please contact support@supermicro.com for BIOS 2.7 availability.  BIOS 2.7 should fix the issue.
