How About On an Intel Desktop Board DQ87PG? Any risk of bricking beyond the normal risk?

[CABLE353]

I have a DQ87PG motherboard and because it's foundry source is intel, they've made all the bios/uefi firmware for it, as recent as 2018 being the last update. I'm wondering if there's any risk of bricking this motherboard beyond repair by doing this mod, beyond any normal risk that comes with firmware modding. If it had it in their foundry, and have been producing their own firmware for it, does that change the process for which I'm to go about this? Or would it be the same as any other Haswell system chipset, and I'm overly worried about the whole thing? I've done some firmware modding in the past(I'm a part of the Wii homebrewing scene as a user), but with the stuff I've modded, it's a little bit more widely known and the steps are a little bit simpler. I also am curious if I do end up seeing the worst(moboard is bricked), how would I reset or recover it?

Afaik there isn't anyone who has tried ReBarUEFI on an Intel motherboard (because of how rare they are) but you could try to be the first. You should keep a backup of the stock BIOS because iirc Intel doesn't have it available for download anymore.

Dont' think there's anything you can do about it sadly, a lot of Haswell (but not Broadwell) boards are missing 4G decoding and no one figured out how to mod it back in.

Probably best to leave the system as is you're only going to brick if something goes wrong when flashing.

Maybe it's my simple thinking but couldn't it be that a haswell with that full option in the bios could be uploaded and that option copied/pasted into other bios files for other haswells? It would be haswell on haswell right? Maybe it's universal?

I was able to get my board into Service mode using the realtek chip jump, and now I can use fpt. I've just dumped my bios. Now what?

No one has tried it even on other more common boards so I don't think it would be that simple.

Currently the only known way to get resizable BAR on your system is the Linux method that README mentions.

Really? So if I were to flash my bios with the patched rebar dxe driver, but without the 4G Decode on (like I totally skipped that step), would it brick my board or give me super terrible performance?
