i'll reformulate my post, as my previous one was rude and pointless, apologies, it s kind of hot currently, doesnt help with patience.
so to the point :
The OP, creator of this thread, Ismail Hastanesi, said clearly he will NOT come back to the thread. Notifying or asking him directly is useless and rude.
In the last pages 18 to 22, someone explained step by step how to _try_ (i insist, TRY), with a certain pourcentage of RISK (like, broken motherboard) how to modify a Bios to add a specific Nvme mod. Reading ALL the other pages will point out that some Bios dont have enough room, that there may be checksum and bios corruption problems, and that it s never easy and "sure shot" procedure.
Even though, once the motherboard is flashed and detects the Nvme, it doesnt always mean you ll be able to boot on it, or to boot "at all". Sometimes the pre-integrated extra controllers (ex : SATA3 which didnt come in the bridge chipsets but as extra chip on the board) will conflict and freeze the boot. In those case, one MUST go to the bios and disable the extra controllers BEFORE plugging the Nvme on the board.
For any reason (loss of settings in the bios, or bios auto restore in case of wrong O/C, or power outage issue) if the bios goes back to default and freezes, you have to unplug the nvme, go back to the bios, set it up correctly again, plug back the Nvme. In case of dual bios systems, i advice, once everything is super tested and stable and fine with no more surprise, to sync the backup bios with the current one, and also, to make a backup on a usb key (that will keep the options in case you forget about the settings). another sure shot method : take pictures of all the bios sections.
In case of major breakthrough (honestly, i wonder what more can be done) or a clean HowToAddAnyNvme, it would be nice to have it at the last page after this post, and / or pinned on page 1 (i wonder if the moderator can do it, i guess it s technically possible)
But seriously, posting "help me i have a non X58 board" or "i have an unlisted hardware what can i do" is rude, too, because it clearly shows the topic wasnt read, and it disrespects all the contributors in this discussion.
There is NOTHING missing in the previous 22 pages. All is listed, source of the bios pre modification, files of original mods added, methods, tools, links, backups, methods, litterally, everything is here, there is no point in asking for "more" as i really dont see what could be missing concerning adding a Nvme on a X58 board.
If your motherboard bios is not listed on page 1, if the bios was not tested successfully, if the nvme drive reference you have does not show anywhere, it s going to be a tough process to try and make it right. If you manage to make it right and functionnal, be careful before posting "it works" and never forget to put a "at your own risks" disclaimer.
have a nice summer all, dont forget to cool down the nvme they hate high temperatures.
