Power disconnected by accident during BIOS Update

Sort by date Sort by votes
I understand, then I can't do it. I thought that SPI port indicated some other port on the motherboard without having to use Eeprom. Also because I think that the bios chip on my motherboard is so low, so low, that the Eeprom tweezers will never be able to hook onto the chip

Thanks for posting. But I'm reading that it's very dangerous to flash via SPI if you're not an expert. Guys, I want to find a solution to the USB Flash port without having to void the warranty.

I don't think the Eeprom method can be done on my board, the bios chip is not high enough to connect an Eeprom tweezers. It's very low compared to the other chips. So I don't think I could succeed with Eeprom.

The SPI method, from what I read, is very dangerous for non-experts.

Is there something simpler, like a bare board CD player? Or another method. But nothing complicated that only an expert programmer can do, and nothing that would void my warranty. After all, the bios was just damaged during the reading.

Not more dangerous than normal flashing directly on the BIOS chip. You first read the BIOS chip, if that works, that is already a good sign (check the content to make sure it's not just all zeroes). Then you just flash as you normally would with the usual method. At the end you can verify it and read it out again to see if it succeeded.

What i meant was the process via JSPI1 header. You'd do all the same steps as flashing directly to the BIOS chip with the clamp.

I don't understand what you mean. What does it mean to do the same steps on JSPI as the flash with the clamp? And above all, what is the clamp? Look, I don't know anything about chip programming and electronics in general. If you ask me to assemble a PC or use software, reprogram Windows, etc. I understand enough, but reprogramming electronic components for me is like speaking Arabic. Also on the board I don't find any PINs with SPI or JSPI written on them, there are some PINs without a label at the base of the motherboard, similar to those in the photo, they are probably those, but honestly I find it all too complicated. And even more absurd I find a port for flashing the bios mounted on an MSI motherboard that is useless if the bios fails.

I linked you the pinout of the JSPI1 header. That means, this header (a set of pins on the board) is connected to the pins on the BIOS chip, pretty much. Eight pins of the header directly correspond to the eight legs/pins on the BIOS chip. Therefore, if you hook it up correctly, the following procedure would be no different than clamping directly onto the BIOS chip and flashing that way. With clamp, i mean what you called "tweezers". What you put on the BIOS chip.

Here is another example,

The left is the JSPI1 header, the right is the BIOS chip, they're connected. So anything you'd do on JSPI1 gets to the BIOS chip. This is the same pinout as the one i linked before, so it seems it's always the same. Now, apparently, if you don't have a seperate JSPI1 header anywhere on the board, then the JTPM1 header will do this job. With the same pinout as you see here. That is the header to the left of the BIOS chip.

If you find all this way too complicated (and it is not easy, admittedly), then you need to find someone who has done this kind of thing before. Ask some repair shop or something.

Ah, now I understand. Yes, JTPM1 is there. But I'm not an expert in these things and so I won't get involved. I prefer to wait and return the card to where I bought it. Thanks for the explanation, in fact it's not very easy if you don't have practice. Especially if the card is not to be thrown away, it's better not to risk damaging it

Headers like that are very handy. I used to flash unsigned BIOS mods a lot (and still would if I had a reason to) and that beats the heck out of removing the chip and soldering it back again. Back in the day I soldered some surface mount SOP8 sockets onto my motherboards so I could swap BIOS chips by simply lifting it out and dropping another IC into the socket and latching the lid. Those alligator clips were never great. Sometimes they were difficult to attach and would come loose if you disturbed anything even slightly.
