Have you good news for me!

how did you get the modded bios to flash on the z820? hp uses a checksumed bios and if the checksum is changed the bios update fails

Hi David
I used a USB and it said flashed successfully ! I did it like 4 times
Is there a way to check if the flash included the nvme DXE ?
Check sum : is there any info you can provide that I can use to get this to work please ?

Thanks

Hi Fernando
Can’t see PATA_SS
The flash says successfull , could it say successfully flashed but not include the Nvme DXE ?

If so is there another way around this to put the nvme DXE in the bios ?

i decided to open the z840 ( which is NvmE compatible ) bios and extract the nvmeexpressDXE + NVMeSmm. I then inserted them into the z820 bios and still no joy.

Fernando i have noticed in the z820 DXE section that there is a sub directory for each DXE called "Compressed" and in this compressed sub drop down is where the " P32 image Section" files and "User interface Section" files seem to need to be for ALL DXE Files in UEFITool.
I am thinking maybe this is the problem because when i insert the provided NvMeDXE into the z820 bios using UEFITool it leaves the P32 +User section files UNcompressed with NO drop down sub directory........!

Any idea on how to create a compressed sub directory ?

If anyone has advice for HP systems and getting this to work is appreciated.

Thanks

Hi Fernando,
Just to clarify
Please see picture above.
The green blocks are all identical DXE Drivers for the z820 ( Notice the layout )
The orange blocks are the compressed P32 Image section + User Interface Section within each and every DXE for the z820.
The red block represents the inserted NvME DXE ( Notice its layout is different and i am assuming that this might be the problem ?)

I am offering anyone a $100 USD PayPal Gift GUARANTEED if you can successfully get my 960 Pro to load on its own through the BIOS as "Windows Boot Manager" on my z820.> ( Hope i haven't broken any rules ) I know this can be done the question is how.

Thanks

Hello all, any way to add nvme boot support into GA-P55-UD3L and 78LMT-USB 5.0 ? Both boards have SATA2 controllers, from my little research clover method will work right ? Thanks for the info

Hi, is there a recommended PCIe - M.2 adapter that is recommended? My chipest is Z68. Own Legacy Bios, heatsink are advantages.

Hello. I made an account here to say, 1) thank you for this process, and 2) when installing the driver to an asus P8Z68-V GEN3 BIOS it allows boot from a nvme drive, but other data controllers stop working and no other drives ate reported to windows. Any ideas on how to correct?
