Hi,
Not even a jumper setting on the MB that allows factory restore of the BIOS then ? Those machines aren't even that old really.(in order of ascending age).
I don't know the capabilities of the first one; it might support BIOS recovery. The other two do not. I think the only option for recovery of a failed BIOS upgrade would be replacement of the BIOS chip with a working one.
Cheers,

I have no#3 too, Revision 2 of it , running an Old modded Bios from TweakTown.... mod 2_fh .... so am in the same boat Currently but the MB has Gigabyte's Dual Bios ( only see on page 8 of the Manual) , there is no way to access the 2nd bios though it will have whatever the Board originally came with in it , I also have an older EP45_UD3P and it has saved me there twice in the past , the issue with that MB is the newer Bios require a 2mb Bios which can only be done in Windows via @VGA the 1st time (subsequent bios can be done normally) which is a bit nerve wracking.... it is supposed to all happen automatically but there are a couple of ways to try and force it if needed.
--GIGABYTE--DUAL BIOS WEB
Recover from GIGABYTE Backup BIOS (Only for motherboards with Dual BIOS technology)
Method #1:
- Shut off the powersupply by pressing the button on the ”PSU” or by removing the power cable.
- Press the powerbutton 3-4 times to empty the stored energy in the power supply.
- Turn on the powersupply
- Press and hold the powerbutton, the system will start the bootup procedure but will shut down after a few second. Release the powerbutton after the system have shut down completely.
- Press the powerbutton to start the system.
- If this technique was successful the system will boot and you will see the following image.
Method #2:
- Shut your PC down.
- Hold the power AND the reset button for about 10 sec, than release.
- Backup BIOS should kick in anytime soon now.
Method #3:
- Short out pins 1 and 6 on the main BIOS chip (pin #1 should be marked with a red dot or whatever)
- Tell a friend (or a relative) of yours to press the power on button
- Remove the ghetto-like jumper you’re holding between pins 1 and 6 as soon as you hear a beep.
- Backup BIOS should kick in again and everything will (hopefully) be fine.
If you still cannot get the system to boot please try with another graphics card (internal graphics should also be tested if available), test another CPU/APU and different memory modules. If the system is still not booting up, then please request RMA for the motherboard.

Would you mind posting the link to the original post where you found this info?
As you can see, I don't have any leading zeroes. Furthermore, the PDF you supplied (direct link from Intel would be fantastic, in case they make changes to it that this copy will not have) only goes back to Sandy Bridge CPUs - mine is older, a Bloomfield (Core i7 965 EE) and thus I (would normally) suspect that they have not released an update.
However, if you go to download the Linux* Processor Microcode Data File from Download Linux* Processor Microcode Data File you can see in the list where my CPU is listed as being a valid CPU for the update.
Furthermore, if you visit this support page for my CPU, Downloads for Intel® Pentium® Processor Extreme Edition 965 (4M Cache, 3.73 GHz, 1066 MHz FSB) - you can see the Linux* Processor Microcode Data File listed multiple times. So, microcode updates for my CPU are available, so that PDF is either incomplete, or there is more information that users of older, legacy equipment need to know as well.
Finally, that PDF was released after the newest microcode from 18 Jan was posted - but that microcode has been removed from download - I suspect because of the issues that it led to. I happen to have a copy of it on my machine (and it is different from the one released in Nov 2017).
Since I have both files, (and the ability to download others from Intel) I can actually compare the different microcode files (94 in the Nov 2017 release, if I am reading the .ZIP file structure correctly) and actually verify if anything has been changed - as soon as I figure out which one is for my CPU.
Actually, after older 486 boards the OEMs started offering flash utilities to reprogram the EEPROMs that stored the BIOS info. But almost every BIOS I've ever worked with (and on legacy machines, from 496 through Core i7 1st generation machines) had the BIOS reset to default values in the BIOS itself. However, depending upon what choices your BIOS offers, a value change (particularly like one that changes your SATA drive drive loading from AHCI to 'standard' / IDE) may (and most likely will, if you're running Windows) render your machine unable to boot at all.
^^^^ This. Most machines offered this as well, and some not so old (like mine) had button on the motherboard to power on and off the board and reset the CMOS (and also used a jumper to do the same, just in case). But I can also reset to default values from within the BIOS itself.
Everything you never wanted to know about the BIOS:
BIOS - Wikipedia
Yeah, you can say what you want about WikiPaedia - but the links at the end are real links....and that is where the information comes from.
This is the Kaby Lake CPU in one of my PCs:
Anybody know exactly which lines(s) refer to MCU? Intel Microcode Revision Guidance says 80 shouldn't be used, but 0x70 should. This PC should be OK since I just got a new BIOS update about a week ago that supposedly addresses Meltdown and Spectre. But I have a couple of others I need to check.
