What CPU are you using with your DH77EB? I recently attempted to update the BIOS on a couple of DH77EB boards from 0053 to 0097, and both boards could not boot afterwards. I had a Core i7-3770K CPU installed, which I finally discovered was related to the boards failing after what appeared to be successful updates.
Flashing from 0053 directly to 0097 seems to bring about so many changes as to make it risky. It may be better if you can flash back to 0053, to see if the BIOS setup works again, then gradually flash forward with incremental BIOS revisions. Another tip: after completing a BIOS flash, disconnect the board from the power supply, pull the 3V coin battery from the board and wait several minutes before reversing the steps.
I am only guessing here, but I suspect the differences in Intel ME firmware revisions accompanying the different BIOS releases may have to do with board not behaving properly after a BIOS update.
My two DH77EB boards that won't boot after flashing to 0097 BIOS had to be restored by extraordinary means that I won't go into here.
I am using a vanilla, non-K 3770. I managed to go to 0071 and decided to stay there for the moment. Though it might be worth the trouble to go one step higher and trying the battery-trick.
So I guess I am lucky that my board boots at all after all the flashing I did! I did 12 flashes in total, ending up with going step by step from 0053 to 0071.
One issue I am looking to solve by updating the Bios is that I can only boot from the msata ssd by explicitly selecting it in the boot menu, not by setting the boot order in setup. Another is that I am getting SMBios not found when using UEFI boot.
I have 2 computers using this motherboard. I updated both to BIOS version 0099 a few weeks ago and haven't noticed any issues. Last night I replaced my OCZ Agility 3 SSD in my HTPC with an mSATA drive because the case is too small and I just had the previous drive stuck to the inside of the case with double-stick tape.
All went well with the imaging, but when I tried to enter bios to make sure my boot order is set up properly, my computer reboots every time I press F2. I can pull up the boot menu with F10 no problem. My computer boots to the correct drive, but I'm still concerned that I cannot enter BIOS setup to make any changes. I did not have this issue last week on my other computer when I entered the setup to change from AHCI to RAID.
It seems like most of the cases are for people jumping from very old BIOS to the latest versions and using the express method.
I recommend you to try using the recovery update or the F7 method and not to jump that many versions in a row. Some important changes are made in some of the updates that might cause a conflict with some configurations.
