BIOS for ASUS Sabertooth Z97 Mark 2 Rev 1.01 required

[Markie76]

Hello,

Am looking at a friend's desktop PC which after a BIOS update no longer boots and displays random behaviour.
I have tried doing a BIOS update with the quickflash USB method which runs for around 70 seconds which seems short for a 8mb file - but this hasn't helped.

The motherboard is;

ASUS TUF Sabertooth Z97 Mark 2 rev 1.01

I have a CH341a programmer and I have removed the Winbond 25Q64FVA DIP8 chip from the mobo and done a dump which is attached:

Please could someone have a look at the file if it is corrupt and tell me which version BIOS it is - much appreciated

Thanks,

Mark

Thank you very much for your quick response

I erased the chip.
Flashed it (took over 3.5 mins)
Verified ok.

The first time I powered it on, the CPU LED switched on then went out, then the RAM LED switched on - then the mobo powered off.
Then it powered on again, the CPU LED came on and stayed on

The mobo responds to reset or holding the power switch but it either stops on the CPU LED, then powers off and sometimes just power cycles without the CPU LED switching on.
The green power LED turns on & off correctly if PSU is on/off.

I have tried clearing CMOS and removing the backup battery but makes no difference.
No beeps on the speaker.

I have checked and reseated the CPU (i5-4460 SR1QK) and all pins look fine.


Anything else I should try?

Thanks,

Mark

Double check your procedure, the bioa file I posted has the MAC, serial and UUID added.

Hi,

Ok, procedure is;
Plug chip into Ch341a.
Plug programmer into laptop.
Start programmer software.
Detect chip - check it is correct (25Q64FV)
Read
Erase
Write
Verify
Shutdown laptop
Install chip back into socket
Press power on while keeping fingers crossed.

If the MAC, serial or UUID is incorrect - will that be the issue?

Thanks,

Mark

This is file non MAC,UUID and serial number, try it.

Thank you for your help.

Using ASprogrammer, I opened your file, then clicked on 'detect chip' and from the list of 3 selected 25Q64FV.

On the 'Programme IC' menu I clicked on: Erase, Blank Check, Write & Verify.
Then I clicked on Programm IC and it started.

It took 2min 43secs to write and 1min 10secs to verify.
Success was confirmed.

Then I put the chip back in the mobo socket, inserted the backup battery, connected the PSU 24 pin & 12v connectors and all front panel switches and a speaker.

The first power on;
turned PSU on and the green LED illuminated.
Pressed the power switch and the red CPU LED illuminated.
The RAM LED also flashed briefly.
Then after about 0.5 second the CPU LED turned off and RAM LED illuminated.
The RAM LED was illuminated for about 1 second then turned off.
Nothing more happened.
The CPU heat lid was warming up.

After this firm power on all it does is powers on and stays on the CPU LED.
When the CPU LED turns on the CPU fan speed increases slightly.
Responds to reset switch and when power switch is held for 4-5 seconds.

Try manual select chip, not auto detect.

Try manual select chip, not auto detect.

This time I selected the IC manually from the list: SPI -> WINBOND -> W25Q64FV

Flashed in same way.

Took battery out while it was flashing.
Then installed chip then battery.

Turned on PSU power and green LED illuminates.
CPU fans comes on.
After 5 seconds red CPU LED illuminates and fan speeds up little bit.
After 3 seconds the power turns off.
Then after 2 seconds it starts up again CPU fan spins and red CPU LED illuminated and fan speed increases a little bit.
Then it stays like this.
If I reset, it starts up and stays with CPU LED on and fan spinning.
If I hold power button it turns off after 4-5 seconds and if I press again it turns back on.
