Earlier this week I was given a file and was able to successfully update my motherboard from BLH6710H.86A.0146.2011.1222.1415 to BLH6710H.86A.0163.2018.1023.1559
I had a second PC here that I wanted to update as well. Today i flashed it from BLH6710H.86A.0105.2011.0301.1654 to BLH6710H.86A.0163.2018.1023.1559 and the last thing it showed was "Flash update has completed successfully."
Upon turning the unit back on it runs the fans but shows no video, no beeps.
I removed the ac power, pulled the CMOS battery for 20 minutes and tried to POST again; still nothing.
I attempted a recovery Flash by having a USB drive with the BIOS being the only file on it in a USB port, all SATA drives disconnected. Pulled the yellow jumper but upon turning on the unit it still shows no video and seems to not attempt to recover the BIOS...
Maybe recovering BIOS is the wrong thing anyways since it said the update was successful but typically a successful update leaves the PC in a usable state. Any ideas would be appreciated.
Thanks in advance
Actually, if you had done the original update via BIOS Recovery, you likely wouldn't be in this mess. It may have been too big a jump between BIOS releases. I am unsure there is anything that can be done about this (you've already tried the things I would have tried).
Well I appreciate you n.scott and Doc having the BIOS updates we need but with all the BIOS files gone from Intel's website and never knowing "how many steps is too many" when doing an upgrade it doesn't give me confidence to flash client machines and possibly put them in motherboard purgatory or worse... I'll jumper across the empty cmos battery socket overnight and try the recovery again tomorrow, but I'm running out of things to try. I never heard of flashing a BIOS via the recovery option but you guys clearly know way more on desktop boards and NUCs than I will ever attain.... Years ago I had a similar issue with a motherboard that had a socketed BIOS chip that seemed to flash OK and wouldn't POST afterwards (like this one). I had another identical board that worked and placed a zip tie between the chip socket and the BIOS, booted on the good chip, swapped in the bad /faulty BIOS and flashed and recovered the unit. I didn't get back to the bench to see if the BIOS is socketed on a DH67GD but I'm not holding my breath
For information on the BIOS Update process, consult Intel Desktop Boards BIOS Update Instructions and, for this case, Intel Desktop Boards Recovery BIOS Update Instructions.
To help you better, here are my step-by-step instructions for BIOS Recovery:
NOTE: Steps 2-5 only need to be done once for a particular USB flash drive. If you reuse it for another board or BIOS update, just delete any existing .BIO file(s) on it and start at Step 6.
Hope this helps,
