Yes, it's formated to fat32...
I'll have to look into the recovery name...I had it the same name as the current bios (which is the C5FZ.cap) And I ran it both on a 512mb and 8GB drive...
I don't know anything about a.rom file since this board has ALWAYS had a .cap bios on it...

That sounds like correct recovery name! Try more smaller USB drives, and make sure it's in correct flashback port.

.rom file you will know about if you follow the guide I linked. .cap BIOS is a 2kb security capsule, surrounding a .rom BIOS (first 2KB of raw BIOS file in hex is the capsule), that is all. To flash using FPT you will remove the capsule, via extracting the .rom.
That may not be covered in guide, I forget if I mentioned or not. But to do that, you open .cap BIOS in UEFITool, right click on the capsule entry in middle and choose extract body. Or to do manually, open cap file in hex, remove first 2KB, save as .rom
That will be the bios.rom you use with FPT flash method

Interesting. Alright. I'll have to look into it when I get home from work.
Thanks :0

So I'm looking at your guide, and it looks like it's all for intel based boards? My board is an Asus ROG Crosshair V Formula Z...which has the ASUS ROG Flashback...I'm just a little confused by your post because I thought you could only go from a .cap to a .cap..not to a .rom file?

And when I try to run the bios through the UEFI Tool...I can't view the guid... it just shows a bunch of dots and dashes...

edit: So I ran into a new issue..I save the PE32 'as is'...and try to use the extractor..and it sits at 'unknown' for the protocol...?

@tzolak

Please note that all the Bios on the first post are not updated anymore by the thread owner. The latest version is v5 and can be found in the post #110.

Oh. Didn’t know that. I’ll have to check that out then.
Can that be flashed through flashback or do I need to go modify the lock?
Thanks @Phoenix48

Ahh! Sorry about the guide stuff, I always forget and think Intel board as default in my brain!

As for the cap/rom, a capsule is a rom BIOS with a security capsule around it, that is all. If your board had been an Intel board and the guide applied, then you would remove the capsule and use the rom to update via FPT

So, ignore all I said about the guide, apologies again! You'll have to use AFU or USB Flashback
Or you may also have luck with this custom Asus AFU based flasher - ASUS Flash Utility v1.13 for WinPE (x86/x64)

I haven't had any kind of luck using conventional flashing or various programs from this forum....I'm not sure what I"m missing...other people have been able to.

I've got 2 different modded bios versions...
Been working on this a week and am no further than when I started....
Any other advice?

ASUS ROG Crosshair V Formula Z..currently running the last official BIOS update which is 2201 (aka C5FZ.cap)...Tried the 3 methods from here: [Guide] How to flash a modded AMI UEFI BIOS

Tried everything I"ve seen here...unless my flash drives are the issue...but I don't have anything smaller than the 8gb except my ancient 512mb which is what I've been working on.

Find other smaller USB Sticks, this is often the issue. Can you flash another version via USB Flashback with any of your USB? Try last older version, so you'll know it's changed once done.
Try to borrow some cheap small ones from neighbor or friend

Bios updated to v6

Changelog:

[Changed] - EFI LAN Intel PRO/1000 UNDI v8.3.10 -----> v8.4.09


>ASUS-Crosshair-V-Formula-Z-2201 MOD v6 (2018-10-22)<

I got my machine to recognize a 970 EVO in a pci slot. I installed windows and ran into major hard drive timeouts. I reinstalled the bios and the timeouts have stopped but total system stability is awful. My 9590 ran rock solid at 5ghz 2400mhz ram speed before I updated the bios. Now I have CPU freezes at 4700 and 1600 MHZ. Anyone have any idea whats going on? Is the speed of the drive crashing the PCI bus?

Since windows update 1809 I have had crashes on my formula Z with a evo 960 and also on another 990fx based system with port resets/errors on my sata controllers as shown in windows event viewer.
(I am using the last mod bios from the OP, and will not update again until windows update has fixed their stuff or AMD provides a fix)

However if I unplug my optical drives (both blu ray drives) the computers becomes stable.

So I think we need an updated driver from AMD to fix this 1809 issues as I can't update my sata driver since the 1809, the latest driver from AMD just wont update SATA for me.

I have tried plugging my blu ray back in several times and every time I do it becomes weirdly unstable( 2 different system and drives), unplugging gets it working again.

So if you have weird issues in windows 10, try unplugging your optical drives and see if things improve.

All the spectres/meltdown fixes forced into windows will probably need updated drives to fully sort out even old stable hardware.


PS: And Cheers to Stickmode and Phoenix48 for the nvme bios has given my old fx system a new lease on life as a htpc.

Fist of all Thank you Stickmode an phoenix48 for the modded bios...finaly booting from my evo :)

But the problem i am facing now is extreme slow ssd speed on my SATA ports (SATA III ssd'd 64 GB) it will not get past 220 MB/s even when i striped 2 ssd' it wouldnt go beyond 250 MB/s

I put all SATA channels in RAID mode so basicly dat should have AHCI compatibilaty

Does anybody have an idear what else i can try to resolve this problem

thanx in advance

Make sure your drives are connected to the correct controller (SB950 I assume), not the ASM1061. Sorry I can't specify which are which, your boards specs say all are red?
