I have a 4770k that's happily chugging along. It's the only windows machine left in the house. I'm not the one using it but it's a fine machine (it used to run linux before I sadly had to downgrade it to pass it along to my SO).
It doesn't get to run any games though. I'll have to see if it's worth it to mess with it.
Somehow I doubt that manufacturers of 13 years old motherboards are going to update their UEFIs... I would love to be proven wrong, but it was hard enough to find a UEFI able to POST with a 2080 super already.
Edit: I apologize for having missed the point entirely. I would like to thank [email protected] for bringing this to my attention. This is actually a firmware hacking mod that works by flashing an already modified (using the tools documented in the linked page) firmware to the UEFI EEPROM of a motherboard.
However I will take the opportunity of hijacking my own comment to point out a couple (important) facts:
Ron Minnich, one of the coreboot developers, once gave me the following, (hardware) life saving advice:
Do not flash firmware on a UEFI EEPROM without having a mean to rescue your board. Meaning buy another chip, get a programmer and keep the original firmware onto the original EEPROM.
Some UEFI firmwares are signed. Obviously, modifying them will break the cryptographic signature. This might entirely prevent you from flashing them, but if it does not, it will in any way always prevent the motherboard from checking the integrity of the file. Therefore, only modify a verified firmware, in a way that you understand. And ideally, sign it afterwards with your own key (or at least keep a copy of its hash in a separate location). This will not help wrt the motherboard, but it will absolutely help you making sure the firmware has not been modified any further.
You might be able to drop the manufacturer's keys somehow[^1] but I would not recommend.
If you still really want to do this, I would advise you to:
Unsolder the eeprom
Solder a slot-in socket instead
Get a new blank chip
Get an eeprom programmer
Dump the eeprom to a bin file
Flash that bin file onto the new eeprom
Test that the motherboard POSTs
Search for cryptographic signatures (possibly compressed, possibly obfuscated - rolling XOR, reversed, etc) in the bin file
Hack around that bin file trying to blank the keys, or better yet, replace them with yours.
Go to step 7, repeat.
Of course, you could always flash the modified bin onto the new eeprom directly at step 6, but what's the fun in that? 😅
Also, if you really do this(!), please don't forget to document. 🙏
[^1]: I doubt they went as far as "fusing" them in the factory, it would be perceived as "overkill" for a general public product - which I assume it is - and would run the risk of bricking upgradibility of the board, should the manufacturer lose the keys. Plus, it doesn't help anything (quite the contrary) if the keys are somehow leaked by the manufacturer.
In order to use the resizable BAR/SAM feature, you need a compatible CPU and GPU. This would make it possible to use older CPUs but you'll still need a compatible GPU which I think it's series 2000 and newer for nVidia, so no.
edit: technically you also need a compatible motherboard, but seems like most of them are, never hurts to double check
I haven't completed read through the tutorial, but UEFITool does exist for Linux. (I had unsuccessfully added NVMe support to an old motherboard previously)
Managed to get MMtools working with wine. But now I am running up against issues with my motherboard and failing the security verification of the modified bios 😅
Whoa. I didn’t know this was a thing! Windows live CD! That’s awesome. Thank you for this! I managed to get MMtools working with wine. But definitely gonna try a few things with this since I’m getting some security verification failures with the modified bios 👀
