I have upgraded AOC-SIMLP-B+ IPMI firmware from 1.50 to 1.59 and there has some event being written (Floppy Initialization, Option ROM initialization…) at IPMI \System Event Log. How can I disable these events?
If the motherboard has BIOS Rev. 2.1 or above then please flash the BIOS again. You need to go into BIOS menu and choose Load Setup Default after you flashed the BIOS.
