As you have seen in the announcement in the desktop boards forum, these files are no longer available.
Unless another member has the file and can post it, you may want to try a site like softpedia.com (being careful what you download).
Also, how do you know you need the "latest", and what the latest is? Just curious.
I understand. I am not trying to be confrontational here, but what is available in bios updates after 0127 that you need? Updating the bios may not do anything for you.
And, the latest is 0131. There are only 0131 and 0130 after 0127, and both are not critical for you.
Attached are the release notes on your bios.
Al is trying to ensure that you understand that (a) this update may be unnecessary and (b) there are risks (bricking, etc.) associated with the installation of *any* BIOS update. You need to decide if you value the fixes/updates included enough to accept these risks. I personally always make sure that I have the very latest BIOS installed -- but understand that (a) I am an expert, (b) I can usually recover from anything that goes wrong and (c) if I can't, as a former member of the group, I know where the original BIOS engineers live.
Understand too that, in this particular case, this BIOS update is NOT going to provide you with the microcode update that will protect you from some aspects of the Spectre vulnerability. You (and your customers) will need to rely on the microcode updates built into Windows 10 and the various Linux distros.
