#1 [OFFER] HP ProDesk 600 G1 DM UEFI v2.33 - NVMe Boot by kvanderlaag 28.05.2021 04:27

I've screwed around with this so you don't have to. HP ProDesk 600 G1 DM (Mini Desktop) BIOS v2.33 (current) modified to insert the full-sized NvmeBoot module for Aptio IV UEFIs as prominently linked everywhere here. You should be able to open this in MMTool and extract any of the modules you like to compare them against the ones in the stock UEFI on HP's website, to be safe. I couldn't be arsed to screw around with FD override to get at the flash, though there does seem to be an unpopulated set of pads for a header to enable FD override - that bit is up to you. The process by which I obtained and modified this BIOS was as follows:

1) Desolder 25-series SPI flash IC from mainboard
2) Insert into ZIF socket adapter in TL-866II+ programmer
3) Read contents of SPI flash to file
4) Open resulting UEFI in MMTool 4.5
5) Insert NvmeBoot module at end of volume containing CSMCORE
6) Save UEFI to new file
7) Burn resultant file back to SPI flash
8) Resolder 25-series SPI flash IC to mainboard

Was it a brutal approach? Yes. Could it probably have been done by unlocking the flash using the ME FPT and using AFUDOS or similar? Probably. I just happened to have a hot air gun, soldering iron, and flash programmer handier than I did any of the ME tools, so...well, this is what I did instead. Anyways, confirmed working; the ProDesk 600 G1 DM boots just fine from the m.2 NVMe slot with this image flashed.

Edit: Oh neat, it's > 6MB zipped and I'm not allowed to post links yet. I guess it's split into two ZIP files now, so enjoy that. You might have to remove the second .zip extension from these things to use it. I have no idea. I'm increasingly regretting bothering to try to share this here.

Second part of the zip file. Again, you might have to remove the last .zip extension.

This post unintentionally left blank.

Remove the trailing '.zip' extension from both files. (This was necessary to get the forum to let me upload the split archive.) You should now have 'ProDesk-600-G1-DM-NVMe.zip.001' and 'ProDesk-600-G1-DM-NVMe.zip.002'. You should be able to extract 'ProDesk-600-G1-DM-NVMe.zip.001' using 7Zip (I don't know if something like WinRAR will work, I haven't used it in years.) This should successfully extract 'ProDesk-600-G1-DM-NVMe.bin'.
