For Asus i have in the past used FD44Editor by Coderush with good results, i think that would be the easiest way to restore the MAC address.

@Pacman
thanks for reply. I edit the bios with FD44Editor but I cant save bios. nothing happen when press Save to BIOS image file... cant save new image

Ok, strange, i will look at it when i get home later.

Hi,
I have bricked MSI B250m Mortart motherboard with winbond 25q128fvsq
According to https://www.pjrc.com/teensy/W25Q128FV.pdf I should be fine with a voltage.

I am searching a way of the cheapest possible flash of motherboard - I have found this topic with Raspberry JSP1 method. Is it possible to flash bios with cheaper raspberry PI zero or PI Zero W ?

Hi...i am a new user here. As per my knowledge to interface 1.8V SPI chip with Raspberry Pi you need a 4 channel bi-directional logic level shifter like this one and a reliable 1.8V power source, otherwise your SPI chip will be dead in 3 seconds after you connect it to 3.3V GPIO pins of RPi. Some SPI programmers can autodetect SPI chip's operation voltage.

Hi, long time no see u.u I've recently bought an ASUS B350-F gamign, sadly the bios chip is almost hidden near a PCIe slot... but luckily there are some header pins. I found this



but I cannot have more info about this connector. Does any of you have some insight?

Hi All,

I bricked a Gigabyte Z68 from attempting NVME modifications. Onboard bios is a MX25L3206E

I have ordered a CH341A and confirming with Non-Asus motherboard, there no need for FD44 editor and adding in MAC address etc. to the CAP file, (Since this is only used by ASUS)

Just download the original image from Gigabyte and program?

PACMAN:
If you wire it like this

pin 17 on the pi to pin 1 JSPI1
pin 21 on the pi to pin 3 JSPI1
pin 19 on the pi to pin 4 JSPI1
pin 23 on the pi to pin 6 JSPI1
pin 25 on the pi to pin 7 JSPI1
pin 24 on the pi to pin 5 JSPI1 nothing to 9, then if nothing, with pin 9 to ground.

otherwise, then try pin 24 on the pi to pin 9 JSPI1 and nothing to pin 5, then ground to pin 5

Leave JSPI 11 & 12 unconnected at this time, if none of this works try only pin 12 to 3.3v.



Hello from germany ! I just registered to this forum because I want to thank you so much !

I had a broken MSI Trident 3 Arctic Mini-PC with i7-7700 and a GTX1070, where BIOS flash within Windows 10 went horribly wrong. - After that the msi trident did not POST anymore, completely broken.
The special form factor H110M board of this trident had a JSPI1 header onboard and an Winbond 25Q128 chip. - Desoldering the bios chip was not an option for me, because everything is so tiny on this mainboard...

So i went for the JSPI1 header solution and detached everything from the mainboard (CPU, GPU, memory, SSDs, Wifi chip) and connected my raspberry pi 2 with flashrom like you described (Just 6 wires, nothing to JSPI1 Pin 9, 11 and 12) - No resistors, no capacitors.
And what should i say: Flashrom sucessfully detected and flashed the ROM-File to the winbond chip and my Trident is up and running again. Saved me hundreds of bucks...

Thank you Pacman !

So the 25q128fvsq is a 3.3 v or 1.8 v chip? Having trouble reading using the standard CH341A software and ASProgrammer software using Soic clip. So wondering what I got to do to get a dump of the chip using a programmer?

The chip is in an Asus Z270-WS and getting blank 'FF' containing files using programmer softwares. Maybe I should also try a raspberry pie?
Thanks

25q128fvsq is a 3.3 v or 1.8 v chip
Look datasheet page 97, 25Q128FVSG, 25Q128FVSQ, 25Q128FVSF are all covered. When reading all 'FF' I'd still assume a contact problem...

I tried 5 times over last night unclipping and reclipping it back on but I appreciate your feeling that its not on right because that puts my mind at ease wether I messed up the flash. Though tried without the battery because first time I used the standard ch341a software with battery and then read not to use it, but Lost-n-bios said try with battery so will try again tonight with ASProgrammer. Heres a photo of how I have set up: [Guide] Using CH341A-based programmer to flash SPI EEPROM (20). Sorry beyond of topic of this RP thread.

W25Q128FV / BV both are 2.7-3.3V chips.

Hi,
Newbie here. I'd like to attempt to reflash the BIOS on a Gigabyte GA-H61M-USB3-B3 Rev 1.1 motherboard. BIOS chips are surface mounted. I bought a SOIC adapter and a 8-bit Logic Level Convertor off ebay in order to lower the voltage from 3.3v to 1.8v (BIOS chip is a Winbond W25Q32FW I think). Problem is, I'm not sure how to wire up the logic level convertor. Ebay listing is here - https://www.ebay.com.au/itm/8-Channel-8-...AZ/113375842840

Any advice would be much appreciated. Thanks!

Hi,

Is my flash chip dead?

1
2
 
Calibrating delay loop... OK.
Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ft2232_spi.
 



I'm using TIAO USB Multi Protocol Adapter (TUMPA) SPI1: http://www.tiaowiki.com/w/TIAO_USB_Multi...SPI_Connector_1


The chip is a Winbond 25Q64FVAIQ : https://www.winbond.com/resource-files/w...%2006142016.pdf

Connection as follows:

1
2
3
4
5
6
7
 
TUMPA SPI             <=====>     Winbond
1 MISO 2 DO
2 Vcc (3.3V) 8 VCC, 3 WP, 7 HOLD
3 SCK 6 CLK
4 MOSI 5 DI
5 CS 1 CS
6 GND 4 GND
 



Checked 3.3V with Multimeter, when running flash rom GND, DI blips so it seems to be working. Tried OS X and linux with same result. Any ideas?

update: System spins fans with the chip in. Without chip, fans wont even spin up, so chip seems OK. I think my cables are poor quality and too long, ~19cm / 7-8"

update^2: shortened the cables and used the SPI2 interface and set the jumpers like here: https://ao2.it/it/blog/2012/09/23/tumpa and it worked.
most likely a loose connection somewhere..


backed up flash. erased and wrote the original bios. booted back into windows and then flashed to the latest bios! system is running again!

@jave - don't guess/think about BIOS ID, get magnifying glass and flashlight and check to be sure. Normally on such an old board 1.8v BIOS chip would not be used, so no converter needed
If it is W25Q32FW then yes you will need 1.8V adapter such as this - https://www.ebay.com/itm/202046860676
Whatever you have may work, if you've seen someone use it in some way, but the above is the only thing I've ever seen used for this purpose.
But, since this is raspberry pI thread, I'm sure there is some way you guys with these can use what you mentioned Hopefully someone will help you with that soon

@e97 - with general CH341A programmer and it's software, for W25Q64FV I have to choose W25Q64BV - so if you can do something similar in your setup it may help
Choosing exact proper ID on CH341A software for me, no matter software version = "sometimes" read OK, but write always fails
Or, sounds like you got it finally, great! I'll leave this info here in case if helps someone in the future
