- 8-pinned PCB goes into the programmer at the 4/4 slot for 25xx BIOS, then cables go from that to motherboard SPI header or other cables used (SOIC8 test clip cable with cli[/clamp) for motherboards with soldered on BIOS
Your board BIOS is removable, so you have to very carefully pry out your motherboard BIOS chip, it's between the PCIE slots near bottom. Use something wooden or plastic, if you did not get a chip/IC puller with your kit.
Wiggle a little at a time from each side, going more carefully and slowly as you near getting it out, because it will bend super easily and the closer you are to getting it out the more prone it is to bend towards one side and trash the legs.
You can stop midway through and slide a thin ribbon or thin set of wires/cables though/between the chip and the socket, then pull snugly straight upwards. Anything you can think of that is thin enough to slide through there will work, thin plastic strip, piece of strong paper etc.
Order you one of these as soon as you can, this way you wont ruin BIOS chips, those legs can bend and break very easily
Once you have the chip out, notice the notch in the socket, the BIOS must always go back into the socket this same way, matching notch is found on the BIOS chip itself, like half-moon or half circle notch on one side of the chip. These always line up
On the programmer, your BIOS chip goes into the rear-most 4/4 slot (Nearest the lever), with the notch in BIOS in the middle of the slot. See the small white diagram on the programmer near rear of the slots w/ lever, there is a little diagram there showing how it goes into programmer (You have 25x)
Here is package of several versions of software, and driver. https://www.sendspace.com/file/gtcmvd
Install the driver first, then for Asus Z170 I found 1.30 software usually works OK. Put your BIOS in, connect the USB cable to programmer and your PC, then open the software.
choose identify chip and if it's W26Q64FV choose BV instead, or visa versa, sometimes you have to try a few if exact match does not work (In this case, I know exact match does not work for W26Q64FV)
Then click read, and then verify, if you get a message buffer/memory and chip match, then click save and upload the file for me to modify for you. Also save a copy somewhere safe so you'll always have a backup of your board details.
To write, I do the following:
1. On the "Auto" menu, uncheck erase and blank check, leaving write/verify checked
2. Erase Chip
3. Blank check
4. Open BIOS file to write
5. Hit auto and wait, once you get memory/buffer and chip match then it's verified and ready to be put back into board.
Upload your backup for me and I will modify for you. First I'll unlock the FD (Flash Descriptor) so you can flash with FPT easier next time around (Be sure you do this yourself on next BIOS too so it stays unlocked - here's how
, see image in second spoiler at section "B")
Then I will unlock "BIOS Lock and SMI Lock" if set, this way you don't get other FPT error when trying to flash modified BIOS, these would be reset next time you flash, Here is a guide on how you get around this next time (or you can always use programmer again!) https://www.win-raid.com/t3908f16-GU...-Mod-BIOS.html
Then I will modify any settings you need changed or enabled for viewing (ie made visible to you in BIOS, that's not currently visible)
You can see all hidden settings in AMIBCP 5.02.0023 in the setup config tab, then expandable sections on left side. Google this, you will find, if not send me PM and I will send you.
And yes, I can also update all CPU microcodes if you want, and Intel ME too if you want that updated, just let me know when you post your backup.
By the way, my guide linked right above, will get around FPT 368 error (BIOS region protected) and other similar errors, I wrote the replies in this thread long ago, before I figured out that method and recently created this guide.
So for anyone reading this in the future, this guide will help you flash modified BIOS without having to use programmer, usually. Error 26 will need programmer, can be unlocked in modified BIOS for next time around, but that needs programmed to the board first.
