| Need to reflash a bricked BIOS |

Did a BIOS update. Even had the thing plugged into a UPS but the thing still got bricked. So, I'm looking at getting this: https://www.ebay.com/itm/XGecu-TL866II-Programmer-PLUS-for-SPI-Flash-NAND-EPROM-MCU-AVR-13-adapter-clip/192725987183?hash=item2cdf5d2f6f:g:PysAAOSwJ3RatMVW:rk:9:pf:0 To reprogram a BIOS chip from a Lenovo M600. The chip is similar to this: http://www.bios-chip24.com/MXIC-MX-25U6435F-M2I-10G-64MBit-SPI-Flash-SOIC-8/en I can get the exact chip details in maybe a day. |

The question is, do you have actual firmware dump to flash? Firmware update which you can download on lenovo website is not suitable. EDIT: just checked that it's not a laptop as I thought, so probably downloaded firmware will be fine. But still not certain as it is not standard ATX motherboard. |

In any case I suggest saving corrupted bios backup before flashing new one. It might be useful for cooking working bios from incomplete update file. |

There's a discussion of that programmer elsewhere, and it's decent, should do the job for you. Make sure that the bios file is the raw image if you're writing it with a programmer, not some other format that needs to be interpreted by the firmware installer, then you're probably alright. While it's unlikely in this case, I know some motherboard vendors were able to supply preprogrammed BIOS chips for their boards in the past - I think this is only likely if they are also socketed, which basically no laptop ones are, but it could be worth a customer service ticket. |

I was planning on reading and saving a BIOS image from a working computer of the same model. I'm in IT so I have quite a few of the same machine. The exact chip in question is: MXIC MX 25U6473F M2I-10G 8C428400B2 L173695 |
