How To Update MSI Bios

[Duzz7]

I want to update my bios for my MSI B75MA-P45 motherboard but I am not quite sure how to do so. Yes I read the how to on the MSI website but I am still a bit confused. Can someone please tell me the step by step process? My bios is currently v1.5 and do I really need the MS-XXXX number? If so, why? Thanks in advance.

It simPle download bios file 1.7 for your mb from msi. Unzip it and copy the Rom or bin file to USB stick. Leave one copy on the hard drive. Reboot and go into the bios. On the efi bios there a utility tab. Click on the tab and you see a tab for bios udating.click on it and when it starts it ask for path to the bios file. Point it to the USB stick first. It read the file and give you a string of numbers matching your mb model. If it ask you if you want to save your bios file click yes. The updater will run and then reboot your pc. On reboot go into the bios set bios to factory default and save and exit. Go back in turn on xmp profile and check that Sata ports set to achi ad video card set as first output if you have a gpu.
