I need a New Bios upgraded to Z77 Extreme 4, with fixes from Specter and Meltdown.
Many users need this update for ASRock Z77 Extreme 4.
Thank you!
@mandrakerj
Everybody needs this, but Intel didn’t release microcode for snd/ive bridge yet. As soon as they release that, I can help you to patch your uefi.
Friend,
Does this new Upgrade Intel Microcode List exist Ivy Bridge z77?

Friend,
Does this new Upgrade Intel Microcode List exist Ivy Bridge z77?
There is no microcode released to public to sandy / ivy bridge yet. Intel had released new microcodes january 8, but it didn’t have sandy e ivy bridge updates.
Não existe microcode liberado ao público para os sandy / ivy bridge ainda. A Intel havia liberado microcodes novos no dia 8 de janeiro, porém não continham atualizações para os sandy e ivy bridge.
@mandrakerj
I edited your motherboard’s uefi, updated the drivers and modules. The microcodes follow those in “Pre-Mitigation Production MCU” according to the Intel document. As soon as Intel release the final version to SND/IVY, I will update this uefi again.

@plutomaniac
Sorry, I edited my posts. I wrote in Brazilian Portuguese because mandrakerj is my compatriot.
Thank you very much, my friend.
Any more questions, this Bios that you have made available for Download is already corrected with Microcode Intel or not?
@mandrakerj
Not yet. Intel didn’t release to public patched microcodes. As soon as Intel release it I will be able to patch the uefi. You can check that the latest microcodes release are from november/2017, without specter/meltdown patch.
Ainda não. Como eu havia dito anteriormente, a Intel não disponibilizou ao público os microcodes corrigidos. Assim que a Intel lançar, eu serei capaz de aplicar a correção na uefi. Você pode conferir no site da Intel que os últimos microcodes lançados são de novembro/2017, ou seja, sem a correção para Spectre/Meltdown.

Hello jcorrea
Now Intel is working for Ivy Bridge and Sandy Bridge, with the Microcode of Specter and Meltdown correction. It would still be in the Beta phase, but should go out at any moment.
Thank you!!
Friend jcorrea, left the update Microcode Meltdown and Specter for Ivy Bridge and Sandy Bridge, 3rd and 2nd Generation Intel.

This Bios you posted for me.
It would be corrupted, with error, or it would be for another Motherboard Model.
But the problem has now been resolved.
I re-recorded Bios through a Recorder.
Thank you

So the BIOS provided by jcorrea doesn't work?
I'm really interested in updating mine as well...
@mandrakerj are you sure?
@slackeritguy I dropped the link. I will try it as soon as possible, if really corrupt, I will upgrade the UEFI and post a new one.
Awesome. Please get back to us.
I’m really interested in updating my Z77 Extreme4 as well.
Good friend
What happened I do not know …
Just know that it started to update and froze, stopped.
Not even halfway …
I waited about 25 minutes and then I had to restart
And then as I said before, it did not start any more.
Bind and Stop on Dr. Debug 4f with 6 beeps in a row.
I tried all the methods and it did not work.
And there was no way to do it !!
I’ll explain why !!
So my alternative would be to buy the Bios Chip Engraved
More here in Brazil few sell and were missing.
And others are not reliable …
I would have to buy on Ebay, but it would take about months to arrive in Brazil
And I needed the Computer.
So I decided to remove the Chip and re-record Epron.
It worked and everything works fine.
Find out that Chjip is clean in White
Because he could not record because there was something to stop it.
For this was Corrupted.
But the problem has been solved!
I chose to record another Bios!
Thanks!
@mandrakerj sorry for the incovenience, glad to know that you recover your uefi.
@slackeritguy I have updated the uefi, I tried it on mine z77 and everything is ok now.
Here is the updated link:

I tried your "old" (March, md5 fe35467a47cb6ebce450e6e22c454c50) mod and it works without problems as far as I can see. Should I be worried? Should I upgrade to the new version (md5 725e576f62da2ae5cb095530bb25a6f6)?
