Question

It seems like Supermicro X9 boards with E3v1/v2 CPUs (X9SCL-F, X9SCL+-F, X9SCI-LN4F, X9SCA-F, X9SCM-F, X9SCM-IIF, X9SCD-F, X9SCE-F, etc.) will not allow you to enter BIOS if the system date is past December 31, 2020. When attempting to enter BIOS, it comes up with a blue screen, and in the bottom right the error code "AB", which apparently means "Setup Input Wait" per Supermicro documentation. If you clear CMOS or manually set the date to before December 31, 2020 from the operating system, you can get into BIOS. We've tried with the latest BIOS (v2.3) and also older 2.x BIOS with the same results.


Does Supermicro plan to release a new firmware version for all of the X9 motherboards for E3v1/v2 CPUs to solve this issue?

Answer

To resolve the issue please update to bios version 2.3a.  If the bios is not yet available for download, it should be available for download starting Jan 22, 2021.
