Hi

Is it possible to nvme boot on an Intel DZ77BH-55K motherboard. Whats the best way ?

Thanks

rsfdpn

@rsfdpn - Yes, you need these two items first though, it's the only way to modify Intel BIOS (Around $6 total shipped)

You make a dump of the current BIOS with programmer, then edit that, then program back to the board

Thanks @Lost_N_BIOS

Ordered the parts on ebay. Where can I find the instructions? There are so many on this site, can you please help pick the right one for my mobo?


rsfdpn

You're welcome @rsfdpn - There is not a super complete and detailed guide that I know of for using these, but I can help you once they arrive if the links below don't fully help.

[Guide] Using CH341A-based programmer to flash SPI EEPROM << This one general "How to flash" it's brief, but pretty good I suppose

Here is package of many software versions and the main driver you need to install

And here, I wrote a brief summary of my general method when using for another member during a chip test

No matter what, before you write anything, make sure you get a verified backup (Chip/buffer and memory match/same)
Then make sure that is valid by dropping BIOS in UEFITool and make sure it looks OK (Similar/same layout/errors as stock BIOS), and open in hex editor and make sure it's not all FF's or 00's
Or have someone check the file for you, that way you know you get a proper backup before you write anything, that way you do not loose your board specific details (LAN MAC ID, serial, UUID etc)

You are awesome @Lost_N_BIOS

Thank you!

You're welcome, post back once it arrives and I'll help you get started if you need!

Hello @Lost_N_BIOS

Here is my motherboard specs. Can I upload the modded BIOS via USB while in recovery mode? If not, I just don't know which is the BIOS chip on the motherboard.

Thanks again.

rsfdpn

Hi @rsfdpn - no USB recovery mode will not work with MOD BIOS, or that would be the standard method used, only flash programmer will work

Show me actual picture of your motherboard and I will circle the BIOS for you. Did your programmer arrive now?

Looks like chip between SB and memory slots, a little to the right, butt I can only find a few not so great images.
Does that chip say SPI or BIOS near it? If not, what about one directly below last SATA Slot, does it say SPI or BIOS near that one?

Hello Lost_N_BIOS!

I used a Samsung 950 Pro 512GB Nvme on the DZ77BH-55K board and it boots. I'm booting Windows 10 on Nvme out of the box with no changes to the BIOS.

Thank you for your support. Much appreciated.

@rsfdpn - great you are booting your NVME now, and sorry I didn't realize this was your SSD or I would have remembered to mention this from seeing Fernando mention it often.
