DH77DF bios update warnings/lessons

$

I have solved my bios problem (see below) but if any Intel personnel see this I hope the next version of bios for this board will support HDMI/1080 video CPU-based graphics.

 

For anyone else who may be interested:

After much trouble/research/trial and error I'd like to warn everyone to NOT use the Windows bios update procedure. Rather use the F7 on boot procedure if you want to update your bios. Also BIOS version 0107 does not seem to support HDMI 1080 video (connected to my plasma TV). I use CPU based video output and I have to connect an old DVI, 1024x768 resolution monitor to access the bios. Otherwise, pressing F2 just reboots my system.

 

Further after the Windows procedure failed and my bios was corrupted here is how I was FINALLY able to restore my bios.

 

I got most of this info from here so thanks to the original poster:

Re: DH77KC BIOS update killed my machine

 

Download the EARLIEST bios version (I used 0069) .BIO file and copy it all by itself to a FAT32 formatted USB flash drive.

Shut down your computer and disconnect the power cable.

Completely remove the jumper from the bios jumper block (see your manual). This puts the bios into recovery mode.

Disconnect the battery on the motherboard. I don't know how long but I waited about 15 minutes.

Disconnect ALL SATA drives from motherboard.

Reconnect the battery, put the USB flash in a USB2 slot. (Don't know for sure if that matters but it worked for me).

Connect to power and boot.

If your flash drives had a light it should light up and may flash. While my unit was flashing the bio the front power LED flashed. It takes quite a while--maybe up to 60 minutes. If any LEDs on your computer/board are flashing leave it alone.

After my power LED stopped flashing, I shut down my computer (it actually my have shut down by itself, I can't remember).

I removed the flash drive, disconnected the power, replaced the bios jumper to position 1-2, reconnected my SATA drives, reconnected the power and booted up. F2 sent me back to the bios!

 

Pertaining to my info in the first paragraph, the 0069 bios worked with my HDMI/TV connection. After that I DID upgrade to the 0107 bios using the F7 boot method with just the 0107 .BIO file on a flash drive but I have to connect an old monitor via DVI in order to access the with F2. Hopefully the next version of the bios will support HDMI/1080 resolution.
