    Posted: 17 Jun 2015 at 9:54am
I received a modified Z77 Extreme4 UEFI BIOS from John at ASRock.  And with his permission, I'm sharing the file with you.
It allows boot support for the SM951 AHCI, and most likely the XP941 as well.  Not sure about the NVMe version.  You'll have to use one of your x16 slots and a 4x PCIe add-in card like the DT-120 from Lycom or something similar to get the maximum speed from this SSD.
  
Download: Z77EXT4(P2.90M).zip
 
In addition, I have a UBU modified 2.90M BIOS. 
It contains:
-Updated Intel RST(e) OROM (13.1.0.2126), which is the newest version for the 7-series chipset.
-Updated Intel EFI GOP driver (SandyBridge v2.0.1024 / IvyBridge v3.0.1027).
-Updated Intel LAN OROM (1.5.67), Broadcom LAN OROM (16.8.0) and Broadcom EFI UNDI (16.8.5).
-Updated ASMedia SATA OROM (v0.951).
-And the latest Intel CPU Microcode for SandyBridge (6A7-28) and IvyBridge (6A9-19).
This is the BIOS I'm running and it works perfect.
 
Download: Z77EXT4-UBU(P2.90M).zip
 
Using this modified BIOS, I was able to install Windows 7 using a thumb drive in a USB2 port.  You cannot use a USB3 port, Windows 7 does not have a compatible USB3.0 driver and you will have no keyboard or mouse when the Windows installation starts.  Make sure CSM is enabled and set your  primary boot device to the UEFI: variant or your thumb drive.  If you install to unallocated space, Windows will create the necessary EFI partitions and format the drive as GPT on its own.

I installed the bios 2.90M UBU version. I was forced to flash it from 2.90 cause it didn't change any settings but it remembered what I selected. Anyways, the system bios date and video bios date changes depending on the fastboot setting, ULTRAFast system bios date 6/9/2015 or 5/3/12 (changes randomly with restart)- video bios date unknown .. FAST/Disabled system bios 5/3/12 video bios 3/14/12...  not sure if this is something to be concerned about or not. but did run into a problem where my pc did not display anything on screen, dvi & Hdmi on both onboard and graphics card.

The 2.90m UBU bios is a beta bios created by tech support with the exclusive purpose of adding SM951 boot support, as such it is likely that there are some version names/dates in the code that were left unaltered. It is not anything to worry about. The problem with no display coming up, is that ongoing or is it resolved now?

I always do a BIOS reset and load defaults.  Then I do a fresh install of Windows and install all the drivers and updates.  After that you can go back into the BIOS and overclock and tweak it however you want.  I may be pessimistic, but I never expect Windows to work 100% after a BIOS update.  I usually back everything up before I do an update, just in case.

Hi dbranger94, do you still have this BIOS available as the links you have posted are 404'd.


Cheers

FIRST, edit your post to remove your email. It's spam-bait posted in a forum.


Second, get that file direct from ASRock for your Z7 Extreme4 HERE under the BETA Zone downloads.

It would appear that Comcast has erased my ftp site and everything on it.  I'll try to get new links up asap.
