MSI Mainboards !

[Jon Westgate]

I've just been tryng to recover my P67A-GD65 main board with a bcusb, My bios chips are both unreadable, pealing off the stickers removed the print on the chips.
I did figure out that you need to remove the ram and psu connector from the main board else the 3.3v is pulled down.

Ok, I have got somewhere now, but still seeing 3.3v as 2.1v, I have a file flashing very slowly, I doubt it is going to work. I did get it to work once by using the 3.3v jumper to feed the board, but now that just shows not device detected if I do that. The one that so say worked didn't boot, hence the reflash, it would be interesting to know which of the 2 chips I'm flashing, unless its both at once

Have you tried connecting as per this pdf , you should only be programming one chip , once that is recovered , it should boot , then with the proper bios tools you should be able to recover the 2nd chip.

Yup, that is exactly what I'm doing, but I have no way to know whih chip I'm programming, plus the voltage on the chip is too low, its 2.1v it needs to be at least 2.9v according to the datasheet Its a W25L640 (8MB) (64Mb) chip. Oddly if I introduce 3.3v the chip is not recognised. (Though I did have it work once).

You should be programming the first chip closest to the jtag header , you can verify this with a multimeter on the pins .

Hi to you Jon and to my old friend D3m0n, i only wanted to know if you got it to work with the method with the small wire. I´m having another BIOS-sick mainboard....
